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.
Imports System Imports System.Reflection Imports Microsoft.VisualBasic Class [MyClass] Public myField As Integer = 10 End Class '[MyClass] Class Type_TypeHandle Public Shared Sub Main() Try Dim [myClass] As New [MyClass]() ' Get the type of MyClass. Dim myClassType As Type = [myClass].GetType() ' Get the runtime handle of MyClass. Dim myClassHandle As RuntimeTypeHandle = myClassType.TypeHandle DisplayTypeHandle(myClassHandle) Catch e As Exception Console.WriteLine("Exception: {0}", e.Message.ToString()) End Try End Sub 'Main Public Shared Sub DisplayTypeHandle(ByVal myTypeHandle As RuntimeTypeHandle) ' Get the type from the handle. Dim myType As Type = Type.GetTypeFromHandle(myTypeHandle) ' Display the type. Console.WriteLine(ControlChars.NewLine + "Displaying the type from the handle:" + ControlChars.NewLine) Console.WriteLine("The type is {0}.", myType.ToString()) End Sub 'DisplayTypeHandle End Class 'Type_TypeHandle
