Introduction

Extended XML Serializer for .NET 4 and .NET CORE.

Support platforms:

• .NET 4.5
• .NET Platform Standard 1.6

Support features:

• Deserialization xml from standard XMLSerializer
• Serialization class, struct, generic class, primitive type, generic list and dictionary, array, enum
• Serialization class with property interface
• Serialization circular reference and reference Id
• Deserialization of old version of xml
• Property encryption
• Custom serializer
• Support XmlElementAttribute and XmlRootAttribute
• POCO - all configurations (migrations, custom serializer...) are outside the clas

Standard XML Serializer in .NET is very limited:

• Does not support serialization of class with circular reference or class with interface property.
• There is no mechanism for reading the old version of XML.
• Does not support properties that are defined with interface types.
• Does not support read-only collection properties (like Xaml does).
• Does not support parameterized constructors.
• Does not support private constructors.
• If you want create custom serializer, your class must inherit from IXmlSerializable. This means that your class will not be a POCO class.
• Does not support IoC

The Basics

Everything in ExtendedXmlSerializer begins with a configuration container, from which you can use to configure the serializer and ultimately create it:

var serializer = new ConfigurationContainer()
                                            // Configure...
                                            .Create();

Using this simple subject class:

public sealed class Subject
{
    public string Message { get; set; }

    public int Count { get; set; }
}

The results of the default serializer will look like this:

<?xml version="1.0" encoding="utf-8"?>
<Subject xmlns="clr-namespace:ExtendedXmlSerializer.Samples.Introduction;assembly=ExtendedXmlSerializer.Samples">
  <Message>Hello World!</Message>
  <Count>6776</Count>
</Subject>

We can take this a step further by configuring the Subject's Type and Member properties, which will effect how its Xml is emitted. Here is an example of configuring the Subject's name to emit as ModifiedSubject:

var serializer = new ConfigurationContainer().ConfigureType<Subject>()
                                             .Name("ModifiedSubject")
                                             .Create();

<?xml version="1.0" encoding="utf-8"?>
<ModifiedSubject xmlns="clr-namespace:ExtendedXmlSerializer.Samples.Introduction;assembly=ExtendedXmlSerializer.Samples">
  <Message>Hello World!</Message>
  <Count>6776</Count>
</ModifiedSubject>

Diving a bit further, we can also configure the type's member information. For example, configuring Subject.Message to emit as Text instead:

var serializer = new ConfigurationContainer().ConfigureType<Subject>()
                                             .Member(x => x.Message)
                                             .Name("Text")
                                             .Create();

<?xml version="1.0" encoding="utf-8"?>
<Subject xmlns="clr-namespace:ExtendedXmlSerializer.Samples.Introduction;assembly=ExtendedXmlSerializer.Samples">
  <Text>Hello World!</Text>
  <Count>6776</Count>
</Subject>

Xml Settings

In case you want to configure the XML write and read settings via XmlWriterSettings and XmlReaderSettings respectively, you can do that via extension methods created for you to do so:

var subject = new Subject{ Count = 6776, Message = "Hello World!" };
var serializer = new ConfigurationContainer().Create();
var contents = serializer.Serialize(new XmlWriterSettings {Indent = true}, subject);
// ...

And for reading:

var instance = serializer.Deserialize<Subject>(new XmlReaderSettings{IgnoreWhitespace = false}, contents);
// ...

Serialization

Now that your configuration container has been configured and your serializer has been created, it's time to get to the serialization.

var serializer = new ConfigurationContainer().Create();
var obj = new TestClass();
var xml = serializer.Serialize(obj);

Deserialization

var obj2 = serializer.Deserialize<TestClass>(xml);

Fluent API

ExtendedXmlSerializer use fluent API to configuration. Example:

var serializer = new ConfigurationContainer()
    .UseEncryptionAlgorithm(new CustomEncryption())
    .Type<Person>() // Configuration of Person class
        .Member(p => p.Password) // First member
            .Name("P")
            .Encrypt()
        .Member(p => p.Name) // Second member
            .Name("T")
    .Type<TestClass>() // Configuration of another class
        .CustomSerializer(new TestClassSerializer())
    .Create();

Serialization of dictionary

You can serialize generic dictionary, that can store any type.

public class TestClass
{
    public Dictionary<int, string> Dictionary { get; set; }
}

var obj = new TestClass
{
    Dictionary = new Dictionary<int, string>
    {
        {1, "First"},
        {2, "Second"},
        {3, "Other"},
    }
};

Output XML will look like:

<?xml version="1.0" encoding="utf-8"?>
<TestClass xmlns="clr-namespace:ExtendedXmlSerializer.Samples.Dictianary;assembly=ExtendedXmlSerializer.Samples">
  <Dictionary>
    <Item xmlns="https://extendedxmlserializer.github.io/system">
      <Key>1</Key>
      <Value>First</Value>
    </Item>
    <Item xmlns="https://extendedxmlserializer.github.io/system">
      <Key>2</Key>
      <Value>Second</Value>
    </Item>
    <Item xmlns="https://extendedxmlserializer.github.io/system">
      <Key>3</Key>
      <Value>Other</Value>
    </Item>
  </Dictionary>
</TestClass>

If you use UseOptimizedNamespaces function xml will look like:

<?xml version="1.0" encoding="utf-8"?>
<TestClass xmlns:sys="https://extendedxmlserializer.github.io/system" xmlns:exs="https://extendedxmlserializer.github.io/v2" xmlns="clr-namespace:ExtendedXmlSerializer.Samples.Dictianary;assembly=ExtendedXmlSerializer.Samples">
  <Dictionary>
    <sys:Item>
      <Key>1</Key>
      <Value>First</Value>
    </sys:Item>
    <sys:Item>
      <Key>2</Key>
      <Value>Second</Value>
    </sys:Item>
    <sys:Item>
      <Key>3</Key>
      <Value>Other</Value>
    </sys:Item>
  </Dictionary>
</TestClass>

Custom serialization

If your class has to be serialized in a non-standard way:

public class TestClass
{
    public TestClass(string paramStr, int paramInt)
    {
        PropStr = paramStr;
        PropInt = paramInt;
    }

    public string PropStr { get; private set; }
    public int PropInt { get; private set; }
}

You must create custom serializer:

public class TestClassSerializer : IExtendedXmlCustomSerializer<TestClass>
{
    public TestClass Deserialize(XElement element)
    {
        var xElement = element.Member("String");
        var xElement1 = element.Member("Int");
        if (xElement != null && xElement1 != null)
        {
            var strValue = xElement.Value;

            var intValue = Convert.ToInt32(xElement1.Value);
            return new TestClass(strValue, intValue);
        }
        throw new InvalidOperationException("Invalid xml for class TestClassWithSerializer");
    }

    public void Serializer(XmlWriter writer, TestClass obj)
    {
        writer.WriteElementString("String", obj.PropStr);
        writer.WriteElementString("Int", obj.PropInt.ToString(CultureInfo.InvariantCulture));
    }
}

Then, you have to add custom serializer to configuration of TestClass:

var serializer = new ConfigurationContainer().Type<TestClass>()
                                             .CustomSerializer(new TestClassSerializer())
                                             .Create();

Deserialize old version of xml

In standard XMLSerializer you can't deserialize XML in case you change model. In ExtendedXMLSerializer you can create migrator for each class separately. E.g.: If you have big class, that uses small class and this small class will be changed you can create migrator only for this small class. You don't have to modify whole big XML. Now I will show you a simple example:

If you had a class:

public class TestClass
{
    public int Id { get; set; }
    public string Type { get; set; }
}

and generated XML look like:

<? xml version="1.0" encoding="utf-8"?>
<TestClass xmlns="clr-namespace:ExtendedXmlSerialization.Samples.MigrationMap;assembly=ExtendedXmlSerializer.Samples">
  <Id>1</Id>
  <Type>Type</Type>
</TestClass>

Then you renamed property:

public class TestClass
{
    public int Id { get; set; }
    public string Name { get; set; }
}

and generated XML look like:

<? xml version="1.0" encoding="utf-8"?>
<TestClass xmlns:exs="https://extendedxmlserializer.github.io/v2" exs:version="1" xmlns="clr-namespace:ExtendedXmlSerialization.Samples.MigrationMap;assembly=ExtendedXmlSerializer.Samples">
  <Id>1</Id>
  <Name>Type</Name>
</TestClass>

Then, you added new property and you wanted to calculate a new value during deserialization.

public class TestClass
{
    public int Id { get; set; }
    public string Name { get; set; }
    public string Value { get; set; }
}

and new XML should look like:

<?xml version="1.0" encoding="utf-8"?>
<TestClass xmlns:exs="https://extendedxmlserializer.github.io/v2" exs:version="2" xmlns="clr-namespace:ExtendedXmlSerializer.Samples.MigrationMap;assembly=ExtendedXmlSerializer.Samples">
  <Id>1</Id>
  <Name>Type</Name>
  <Value>Calculated</Value>
</TestClass>

You can migrate (read) old version of XML using migrations:

public class TestClassMigrations : IEnumerable<Action<XElement>>
{
    public static void MigrationV0(XElement node)
    {
        var typeElement = node.Member("Type");
        // Add new node
        node.Add(new XElement("Name", typeElement.Value));
        // Remove old node
        typeElement.Remove();
    }

    public static void MigrationV1(XElement node)
    {
        // Add new node
        node.Add(new XElement("Value", "Calculated"));
    }

    IEnumerator IEnumerable.GetEnumerator() => GetEnumerator();

    public IEnumerator<Action<XElement>> GetEnumerator()
    {
        yield return MigrationV0;
        yield return MigrationV1;
    }
}

Then, you must register your TestClassMigrations class in configuration

var serializer = new ConfigurationContainer().ConfigureType<TestClass>()
                                             .AddMigration(new TestClassMigrations())
                                             .Create();

Extensibility

With type and member configuration out of the way, we can turn our attention to what really makes ExtendedXmlSeralizer tick: extensibility. As its name suggests, ExtendedXmlSeralizer offers a very flexible (but albeit new) extension model from which you can build your own extensions. Pretty much all if not all features you encounter with ExtendedXmlSeralizer are through extensions. There are quite a few in our latest version here that showcase this extensibility. The remainder of this document will showcase the top features of ExtendedXmlSerializer that are accomplished through its extension system.

 

Object reference and circular reference

If you have a class:

public class Person
{
    public int Id { get; set; }
    public string Name { get; set; }

    public Person Boss { get; set; }
}

public class Company
{
    public List<Person> Employees { get; set; }
}

then you create object with circular reference, like this:

var boss = new Person {Id = 1, Name = "John"};
boss.Boss = boss; //himself boss
var worker = new Person {Id = 2, Name = "Oliver"};
worker.Boss = boss;
var obj = new Company
{
    Employees = new List<Person>
    {
        worker,
        boss
    }
};

You must configure Person class as reference object:

var serializer = new ConfigurationContainer().ConfigureType<Person>()
                                             .EnableReferences(p => p.Id)
                                             .Create();

Output XML will look like this:

<?xml version="1.0" encoding="utf-8"?>
<Company xmlns="clr-namespace:ExtendedXmlSerializer.Samples.ObjectReference;assembly=ExtendedXmlSerializer.Samples">
  <Employees>
    <Capacity>4</Capacity>
    <Person Id="2">
      <Name>Oliver</Name>
      <Boss Id="1">
        <Name>John</Name>
        <Boss xmlns:exs="https://extendedxmlserializer.github.io/v2" exs:entity="1" />
      </Boss>
    </Person>
    <Person xmlns:exs="https://extendedxmlserializer.github.io/v2" exs:entity="1" />
  </Employees>
</Company>

Property Encryption

If you have a class with a property that needs to be encrypted:

public class Person
{
    public string Name { get; set; }
    public string Password { get; set; }
}

You must implement interface IEncryption. For example, it will show the Base64 encoding, but in the real world better to use something safer, eg. RSA.:

public class CustomEncryption : IEncryption
{
    public string Parse(string data)
        => Encoding.UTF8.GetString(Convert.FromBase64String(data));

    public string Format(string instance)
        => Convert.ToBase64String(Encoding.UTF8.GetBytes(instance));
}

Then, you have to specify which properties are to be encrypted and register your IEncryption implementation.

var serializer = new ConfigurationContainer().UseEncryptionAlgorithm(new CustomEncryption())
                                             .ConfigureType<Person>()
                                             .Member(p => p.Password)
                                             .Encrypt()
                                             .Create();

Custom Conversion

ExtendedXmlSerializer does a pretty decent job (if we do say so ourselves) of composing and decomposing objects, but if you happen to have a type that you want serialized in a certain way, and this type can be destructured into a string, then you can register a custom converter for it.

 

Using the following:

public sealed class CustomStructConverter : IConverter<CustomStruct>
{
    public static CustomStructConverter Default { get; } = new CustomStructConverter();
    CustomStructConverter() {}

    public bool IsSatisfiedBy(TypeInfo parameter) => typeof(CustomStruct).GetTypeInfo()
                                                                         .IsAssignableFrom(parameter);

    public CustomStruct Parse(string data) =>
        int.TryParse(data, out var number) ? new CustomStruct(number) : CustomStruct.Default;

    public string Format(CustomStruct instance) => instance.Number.ToString();
}

public struct CustomStruct
{
    public static CustomStruct Default { get; } = new CustomStruct(6776);

    public CustomStruct(int number)
    {
        Number = number;
    }
    public int Number { get; }
}

Register the converter:

var serializer = new ConfigurationContainer().Register(CustomStructConverter.Default).Create();
var subject = new CustomStruct(123);
var contents = serializer.Serialize(subject);
// ...

<?xml version="1.0" encoding="utf-8"?>
<CustomStruct xmlns="clr-namespace:ExtendedXmlSerializer.Samples.Extensibility;assembly=ExtendedXmlSerializer.Samples">123</CustomStruct>

Optimized Namespaces

By default Xml namespaces are emitted on an "as needed" basis:

<?xml version="1.0" encoding="utf-8"?>
<List xmlns:exs="https://extendedxmlserializer.github.io/v2" exs:arguments="Object" xmlns="https://extendedxmlserializer.github.io/system">
  <Capacity>4</Capacity>
  <Subject xmlns="clr-namespace:ExtendedXmlSerializer.Samples.Extensibility;assembly=ExtendedXmlSerializer.Samples">
    <Message>First</Message>
  </Subject>
  <Subject xmlns="clr-namespace:ExtendedXmlSerializer.Samples.Extensibility;assembly=ExtendedXmlSerializer.Samples">
    <Message>Second</Message>
  </Subject>
  <Subject xmlns="clr-namespace:ExtendedXmlSerializer.Samples.Extensibility;assembly=ExtendedXmlSerializer.Samples">
    <Message>Third</Message>
  </Subject>
</List>

But with one call to the UseOptimizedNamespaces call, namespaces get placed at the root of the document, thereby reducing document footprint:

var serializer = new ConfigurationContainer().UseOptimizedNamespaces()
                                             .Create();
var subject = new List<object>
                {
                    new Subject {Message = "First"},
                    new Subject {Message = "Second"},
                    new Subject {Message = "Third"}
                };
var contents = serializer.Serialize(subject);
// ...

<?xml version="1.0" encoding="utf-8"?>
<List xmlns:ns1="clr-namespace:ExtendedXmlSerializer.Samples.Extensibility;assembly=ExtendedXmlSerializer.Samples" xmlns:exs="https://extendedxmlserializer.github.io/v2" exs:arguments="Object" xmlns="https://extendedxmlserializer.github.io/system">
  <Capacity>4</Capacity>
  <ns1:Subject>
    <Message>First</Message>
  </ns1:Subject>
  <ns1:Subject>
    <Message>Second</Message>
  </ns1:Subject>
  <ns1:Subject>
    <Message>Third</Message>
  </ns1:Subject>
</List>

Implicit Namespaces/Typing

If you don't like namespaces at all, you can register types so that they do not emit namespaces when they are rendered into a document:

var serializer = new ConfigurationContainer().EnableImplicitTyping(typeof(Subject))
                                             .Create();
var subject = new Subject{ Message = "Hello World!  No namespaces, yay!" };
var contents = serializer.Serialize(subject);
// ...

<?xml version="1.0" encoding="utf-8"?>
<Subject>
  <Message>Hello World!  No namespaces, yay!</Message>
</Subject>

Auto-Formatting (Attributes)

The default behavior for emitting data in an Xml document is to use elements, which can be a little chatty and verbose:

var serializer = new ConfigurationContainer().UseOptimizedNamespaces()
                                             .Create();
var subject = new List<object>
                {
                    new Subject {Message = "First"},
                    new Subject {Message = "Second"},
                    new Subject {Message = "Third"}
                };
var contents = serializer.Serialize(subject);
// ...

<?xml version="1.0" encoding="utf-8"?>
<SubjectWithThreeProperties xmlns="clr-namespace:ExtendedXmlSerializer.Samples.Extensibility;assembly=ExtendedXmlSerializer.Samples">
  <Number>123</Number>
  <Message>Hello World!</Message>
  <Time>2017-11-21T10:55:38.0990077+01:00</Time>
</SubjectWithThreeProperties>

Making use of the UseAutoFormatting call will enable all types that have a registered IConverter (convert to string and back) to emit as attributes:

<?xml version="1.0" encoding="utf-8"?>
<SubjectWithThreeProperties Number="123" Message="Hello World!" Time="2017-11-21T10:55:38.0990077+01:00" xmlns="clr-namespace:ExtendedXmlSerializer.Samples.Extensibility;assembly=ExtendedXmlSerializer.Samples" />

Private Constructors

One of the limitations of the classic XmlSerializer is that it does not support private constructors, but ExtendedXmlSerializer does via its EnableAllConstructors call:

public sealed class SubjectByFactory
{
    public static SubjectByFactory Create(string message) => new SubjectByFactory(message);

    SubjectByFactory() : this(null) {} // Used by serializer.

    SubjectByFactory(string message) => Message = message;

    public string Message { get; set; }
}

var serializer = new ConfigurationContainer().EnableAllConstructors()
                                             .Create();
var subject = SubjectByFactory.Create("Hello World!");
var contents = serializer.Serialize(subject);
// ...

<?xml version="1.0" encoding="utf-8"?>
<SubjectByFactory xmlns="clr-namespace:ExtendedXmlSerializer.Samples.Extensibility;assembly=ExtendedXmlSerializer.Samples">
  <Message>Hello World!</Message>
</SubjectByFactory>

Parameterized Members and Content

Taking this concept bit further leads to a favorite feature of ours in ExtendedXmlSerlializer. The classic serializer only supports parameterless public constructors. With ExtendedXmlSerializer, you can use the EnableParameterizedContent call to enable parameterized parameters in the constructor that by convention have the same name as the property for which they are meant to assign:

public sealed class ParameterizedSubject
{
    public ParameterizedSubject(string message, int number, DateTime time)
    {
        Message = message;
        Number = number;
        Time = time;
    }

    public string Message { get; }
    public int Number { get; }
    public DateTime Time { get; }
}

var serializer = new ConfigurationContainer().EnableParameterizedContent()
                                             .Create();
var subject = new ParameterizedSubject("Hello World!", 123, DateTime.Now);
var contents = serializer.Serialize(subject);
// ...

<?xml version="1.0" encoding="utf-8"?>
<ParameterizedSubject xmlns="clr-namespace:ExtendedXmlSerializer.Samples.Extensibility;assembly=ExtendedXmlSerializer.Samples">
  <Message>Hello World!</Message>
  <Number>123</Number>
  <Time>2017-11-21T10:55:38.3180296+01:00</Time>
</ParameterizedSubject>

Tuples

By enabling parameterized content, it opens up a lot of possibilities, like being able to serialize Tuples. Of course, serializable Tuples were introduced recently with the latest version of C#. Here, however, you can couple this with our member-naming funtionality and provide better naming for your tuple properties:

var serializer = new ConfigurationContainer().EnableParameterizedContent()
                                             .Type<Tuple<string>>()
                                             .Member(x => x.Item1)
                                             .Name("Message")
                                             .Create();
var subject = Tuple.Create("Hello World!");
var contents = serializer.Serialize(subject);
// ...

<?xml version="1.0" encoding="utf-8"?>
<Tuple xmlns:exs="https://extendedxmlserializer.github.io/v2" exs:arguments="string" xmlns="https://extendedxmlserializer.github.io/system">
  <Message>Hello World!</Message>
</Tuple>

Experimental Xaml-ness: Attached Properties

We went ahead and got a little cute with v2 of ExtendedXmlSerializer, adding support for Attached Properties on objects in your serialized object graph. But instead of constraining it to objects that inherit from DependencyObject, *every* object can benefit from it. Check it out:

sealed class NameProperty : ReferenceProperty<Subject, string>
{
    public const string DefaultMessage = "The Name Has Not Been Set";

    public static NameProperty Default { get; } = new NameProperty();
    NameProperty() : base(() => Default, x => DefaultMessage) {}
}

sealed class NumberProperty : StructureProperty<Subject, int>
{
    public const int DefaultValue = 123;

    public static NumberProperty Default { get; } = new NumberProperty();
    NumberProperty() : base(() => Default, x => DefaultValue) {}
}

var serializer = new ConfigurationContainer().EnableAttachedProperties(NameProperty.Default,
                                                                       NumberProperty.Default)
                                             .Create();
var subject = new Subject {Message = "Hello World!"};
subject.Set(NameProperty.Default, "Hello World from Attached Properties!");
subject.Set(NumberProperty.Default, 123);

var contents = serializer.Serialize(subject);
// ...

<?xml version="1.0" encoding="utf-8"?>

Experimental Xaml-ness: Markup Extensions

Saving the best feaure for last, we have experimental support for one of Xaml's greatest features, Markup Extensions:

sealed class Extension : IMarkupExtension
{
    const string Message = "Hello World from Markup Extension! Your message is: ", None = "N/A";

    readonly string _message;

    public Extension() : this(None) {}

    public Extension(string message)
    {
        _message = message;
    }

    public object ProvideValue(IServiceProvider serviceProvider) => string.Concat(Message, _message);
}

var contents =
    @"<?xml version=""1.0"" encoding=""utf-8""?>
        <Subject xmlns=""clr-namespace:ExtendedXmlSerializer.Samples.Extensibility;assembly=ExtendedXmlSerializer.Samples""
        Message=""{Extension 'PRETTY COOL HUH!!!'}"" />";
var serializer = new ConfigurationContainer().EnableMarkupExtensions()
                                             .Create();
var subject = serializer.Deserialize<Subject>(contents);
Console.WriteLine(subject.Message); // "Hello World from Markup Extension! Your message is: PRETTY COOL HUH!!!"

(Please note that this feature is experimental, but please try it out and let us know what you think!)

 

How to Upgrade from v1.x to v2

Finally, if you have documents from v1, you will need to upgrade them to v2 to work. This involves reading the document in an instance of v1 serializer, and then writing it in an instance of v2 serializer. We have provided the ExtendedXmlSerializer.Legacy nuget package to assist in this goal.

<?xml version="1.0" encoding="utf-8"?><ArrayOfSubject><Subject type="ExtendedXmlSerializer.Samples.Introduction.Subject"><Message>First</Message><Count>0</Count></Subject><Subject type="ExtendedXmlSerializer.Samples.Introduction.Subject"><Message>Second</Message><Count>0</Count></Subject><Subject type="ExtendedXmlSerializer.Samples.Introduction.Subject"><Message>Third</Message><Count>0</Count></Subject></ArrayOfSubject>

var legacySerializer = new ExtendedXmlSerialization.ExtendedXmlSerializer();
var content = File.ReadAllText(@"bin\Upgrade.Example.v1.xml"); // Path to your legacy xml file.
var subject = legacySerializer.Deserialize<List<Subject>>(content);

// Upgrade:
var serializer = new ConfigurationContainer().Create();
var contents = serializer.Serialize(new XmlWriterSettings {Indent = true}, subject);
File.WriteAllText(@"bin\Upgrade.Example.v2.xml", contents);
// ...

<?xml version="1.0" encoding="utf-8"?>
