ExceptionCondition
NotSupportedException

The .NET Compact Framework does not currently support this property.

TypeHandle encapsulates a pointer to an internal data structure that represents the type. This handle is unique during the process lifetime. The handle is valid only in the application domain in which it was obtained.

The following example returns the handle of the corresponding type and passes the handle to a method that gets the type from the handle and displays it.

using System;
using System.Reflection;
class MyClass
{
    public int myField = 10;
}

class Type_TypeHandle
{
    public static void Main()
    {
        try
        {
            MyClass myClass = new MyClass();

            // Get the type of MyClass.
            Type myClassType = myClass.GetType();

            // Get the runtime handle of MyClass.
            RuntimeTypeHandle myClassHandle = myClassType.TypeHandle;

            DisplayTypeHandle(myClassHandle);
        }
        catch(Exception e)
        {
            Console.WriteLine("Exception: {0}", e.Message );
        }
    }

    public static void DisplayTypeHandle(RuntimeTypeHandle myTypeHandle)
    {
        // Get the type from the handle.
        Type myType = Type.GetTypeFromHandle(myTypeHandle);      
        // Display the type.
        Console.WriteLine("\nDisplaying the type from the handle:\n");
        Console.WriteLine("The type is {0}.", myType.ToString());
    }
}
