Hi all!

I have an XML and I read and store data from there.
like:

<root>
  <main>
    <1>sample</1>
    <2>sample</2>
    <context>sample</context>
    <context>sample</context>
    <context>sample</context>
    <context>sample</context>
  </main>
<main>
    <1>sample</1>
    <2>sample</2>
    <context>sample</context>
    <context>sample</context>
    <context>sample</context>
  </main>
<main>
    <1>sample</1>
    <2>sample</2>
  </main>
</root>

For some reason with the code below I can't store a list of context per class.

What I have tried:

I'm saving all the "main" to a new class like this:

ht.Add(new HandledTUs { SOURCE = 1, TARGET = 2, context = context,});

Class looks like this:

public class TUs
        {
            private List<string> _CONTEXT = new List<string>();
            

            public string 1{ get; set; }
            public string 2{ get; set; }
            public List<string> CONTEXT { get { return _CONTEXT; } set { _CONTEXT = value; } }

            

        }

None of that code makes sense. What is ht, handledTUs, TUs etc.? Where are those objects created, how is the list populated ... ?

To add to what Richard says, 1 and 2 are not value variable or property names, which cannot start with a numeric character.
So your C# code is bad - it won't compile - and the same applies to XML field names which must also start with a letter of underscore.

So your code is bad, yoru data is bad - I'm not surprised that whatever code you are using won't work!
If I correct your xml:

XML

<?xml version="1.0" encoding="utf-8" ?>
<root>
  <main>
    <A1>sample</A1>
    <A2>sample</A2>
    <context>sample</context>
    <context>sample</context>
    <context>sample</context>
    <context>sample</context>
  </main>
<main>
    <A1>sample</A1>
    <A2>sample</A2>
    <context>sample</context>
    <context>sample</context>
    <context>sample</context>
  </main>
<main>
    <A1>sample</A1>
    <A2>sample</A2>
  </main>
</root>

And use VS to generate the classes:

C#

/// <remarks/>
[System.Xml.Serialization.XmlTypeAttribute(AnonymousType = true)]
[System.Xml.Serialization.XmlRootAttribute(Namespace = "", IsNullable = false)]
public partial class root
    {

    private rootMain[] mainField;

    /// <remarks/>
    [System.Xml.Serialization.XmlElementAttribute("main")]
    public rootMain[] main
        {
        get
            {
            return this.mainField;
            }
        set
            {
            this.mainField = value;
            }
        }
    }

/// <remarks/>
[System.Xml.Serialization.XmlTypeAttribute(AnonymousType = true)]
public partial class rootMain
    {

    private string a1Field;

    private string a2Field;

    private string[] contextField;

    /// <remarks/>
    public string A1
        {
        get
            {
            return this.a1Field;
            }
        set
            {
            this.a1Field = value;
            }
        }

    /// <remarks/>
    public string A2
        {
        get
            {
            return this.a2Field;
            }
        set
            {
            this.a2Field = value;
            }
        }

    /// <remarks/>
    [System.Xml.Serialization.XmlElementAttribute("context")]
    public string[] context
        {
        get
            {
            return this.contextField;
            }
        set
            {
            this.contextField = value;
            }
        }
    }

Then the rootMain class looks like your TUs class.
(VS can generate XML classes for you from XML data - create a new empty class file, and select "Edit...Paste Special...Paste XML as classes" from the menu bar and it will generate classes based on the clipboard data.)
