RuntimeTypeHandle Structure

Represents a type using an internal metadata token.

For a list of all members of this type, see RuntimeTypeHandle Members.


[Visual Basic]
Public Structure RuntimeTypeHandle
   Implements ISerializable
public struct RuntimeTypeHandle : ISerializable
public __value struct RuntimeTypeHandle : public ISerializable

[JScript] In JScript, you can use the structures in the .NET Framework, but you cannot define your own.

Thread Safety

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


[Visual Basic, C#, C++] The following example demonstrates how to obtain a RuntimeTypeHandle.

[Visual Basic] 
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 'MyClass1
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("myRTHFromObject.Value: {0}", myRTHFromObject.Value)
      Console.WriteLine("myRTHFromObject.Type: {0}", myRTHFromObject.GetType())
      Console.WriteLine("myRTHFromType.Value: {0}", myRTHFromType.Value)
      Console.WriteLine("myRTHFromType.Type: {0}", myRTHFromType.GetType())
   End Sub 'Main 
End Class 'MyClass2

using System;
using System.Reflection;
public class MyClass1
    private int x=0;
    public int MyMethod()
        return x;
public class MyClass2
    public static void Main()
        MyClass1 myClass1 = new MyClass1();

        // Get the RuntimeTypeHandle from an object.
        RuntimeTypeHandle myRTHFromObject = Type.GetTypeHandle(myClass1);
        // Get the RuntimeTypeHandle from a type.
        RuntimeTypeHandle myRTHFromType = typeof(MyClass1).TypeHandle;

        Console.WriteLine("myRTHFromObject.Value: {0}", myRTHFromObject.Value);
        Console.WriteLine("myRTHFromObject.Type: {0}", myRTHFromObject.GetType());
        Console.WriteLine("myRTHFromType.Value: {0}", myRTHFromType.Value);
        Console.WriteLine("myRTHFromType.Type: {0}", myRTHFromType.GetType());


#using <mscorlib.dll>

using namespace System;
using namespace System::Reflection;

public __gc class MyClass1 {
   int x;
   int MyMethod() {
      return x;

int main() {
   MyClass1* myClass1 = new MyClass1();

   // Get the RuntimeTypeHandle from an object.
   RuntimeTypeHandle myRTHFromObject = Type::GetTypeHandle(myClass1);
   // Get the RuntimeTypeHandle from a type.
   RuntimeTypeHandle myRTHFromType = __typeof(MyClass1)->TypeHandle;

   Console::WriteLine(S"myRTHFromObject.Value: {0}",__box( myRTHFromObject.Value));
   Console::WriteLine(S"myRTHFromObject.Type: {0}", __box(myRTHFromObject)->GetType());
   Console::WriteLine(S"myRTHFromType.Value: {0}",__box( myRTHFromType.Value));
   Console::WriteLine(S"myRTHFromType.Type: {0}", __box(myRTHFromType)->GetType());
