RuntimeTypeHandle Structure

Represents a type using an internal metadata token.

Namespace:  System
Assembly:  mscorlib (in mscorlib.dll)

<SerializableAttribute> _
<ComVisibleAttribute(True)> _
Public Structure RuntimeTypeHandle _
	Implements ISerializable
Dim instance As RuntimeTypeHandle

The following example demonstrates how to obtain a RuntimeTypeHandle from a type or from an object, and how to turn the handle back into a type.

Imports System
Imports System.Reflection

Public Class MyClass1
    Private x As Integer = 0

    Public Function MyMethod() As Integer 
        Return x
    End Function 'MyMethod
End Class  

Public Class MyClass2

    Public Shared Sub Main()
        Dim myClass1 As New MyClass1()

        ' Get the RuntimeTypeHandle from an object. 
        Dim myRTHFromObject As RuntimeTypeHandle = Type.GetTypeHandle(myClass1)
        ' Get the RuntimeTypeHandle from a type. 
        Dim myRTHFromType As RuntimeTypeHandle = GetType(MyClass1).TypeHandle

        Console.WriteLine(vbLf & "myRTHFromObject.Value:  {0}", _
        Console.WriteLine("myRTHFromObject.GetType():  {0}", _
        Console.WriteLine("Get the type back from the handle...")
        Console.WriteLine("Type.GetTypeFromHandle(myRTHFromObject):  {0}", _

        Console.WriteLine(vbLf & "myRTHFromObject.Equals(myRTHFromType):  {0}", _

        Console.WriteLine(vbLf & "myRTHFromType.Value:  {0}", _
        Console.WriteLine("myRTHFromType.GetType():  {0}", _
        Console.WriteLine("Get the type back from the handle...")
        Console.WriteLine("Type.GetTypeFromHandle(myRTHFromType):  {0}", _
    End Sub  
End Class  

' This code example produces output similar to the following: 

'myRTHFromObject.Value:  7549720 
'myRTHFromObject.GetType():  System.RuntimeTypeHandle 
'Get the type back from the handle... 
'Type.GetTypeFromHandle(myRTHFromObject):  MyClass1 

'myRTHFromObject.Equals(myRTHFromType):  True 

'myRTHFromType.Value:  7549720 
'myRTHFromType.GetType():  System.RuntimeTypeHandle 
'Get the type back from the handle... 
'Type.GetTypeFromHandle(myRTHFromType):  MyClass1

Any public static (Shared in Visual Basic) members of this type are thread safe. Any instance members are not guaranteed to be thread safe.
