XML into Object

Question

I'm trying to deserialize my xml this way: 

public static T MyMethod<T>(this string Myxml)

{

XmlDocument Mydocument = new XmlDocument();

using (XmlTextReader XmlTr = new XmlTextReader(new StringReader(Myxml)))

{

Mydocument.Load(XmlTr);

}

// How do I return the result ?

return ???

}

How do I return my result into MyObject which I created to represent the XML ?

Thanks
