Serilization Explanation is Required

serialization is the process of translating an object that is represented in memory, into a "flat" format that can be stored, usually in a text format, or a byte array.

the serialization needs to be two way- to allow a reader to recreate the object from the flat format.

for example:

int number = 5;

string serializedText = SomeSerializationUtility.SerializeToString(number);
int number2 = SomeSerializationUtility.DeserializeFromString(serializedText );

Asset.AreEqual(number, number2);

of course things get a lot more complicated when serializing objects that have multiple properties, and internal states, and perhaps inner properties that are themselves complex types.

so for example:

public class MyData
{
   public string Text;
   public int Number;
   public List<double> data;
}
</double>

could be represented in the following XML format:

<mydata>
   <text type="string">blabla</text>
   <number type="int">5</number>
   <data type="List<double>"><item>0.0</item></data>
</mydata>

and you should be able to easily see how this data is mapped between XML elements and class properties.
