[C#] XmlSerializer example

// This is the test class we want to 
// serialize:
[Serializable()]
public class TestClass
{
    private string someString;
    public string SomeString
    {
        get { return someString; }
        set { someString = value; }

// Example code
 
// This example requires:
// using System.Xml.Serialization;
// using System.IO;
 
// Create a new instance of the test class
TestClass TestObj = new TestClass();
 
// Set some dummy values
TestObj.SomeString = "foo";

XmlSerializer SerializerObj = new XmlSerializer(typeof(TestClass));
 
// Create a new file stream to write the serialized object to a file
TextWriter WriteFileStream = new StreamWriter(@"C:\test.xml");
SerializerObj.Serialize(WriteFileStream, TestObj);
 
// Cleanup
WriteFileStream.Close();
 
#endregion

FileStream ReadFileStream = new FileStream(@"C:\test.xml", FileMode.Open, FileAccess.Read, FileShare.Read);
 
// Load the object saved above by using the Deserialize function
TestClass LoadedObj = (TestClass)SerializerObj.Deserialize(ReadFileStream);
 
// Cleanup
