RuntimeTypeHandle Structure

Represents a type using an internal metadata token.

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

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

/** @attribute SerializableAttribute() */ 
/** @attribute ComVisibleAttribute(true) */ 
public final class RuntimeTypeHandle extends ValueType implements ISerializable
Not applicable.

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 '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

import System.*;
import System.Reflection.*;

public class MyClass1
{
    private int x = 0;

    public int MyMethod()
    {
        return x;
    } //MyMethod
} //MyClass1

public class MyClass2
{
    public static void main(String[] args)
    {
        MyClass1 myClass1 = new MyClass1();
        // Get the RuntimeTypeHandle from an object.
        RuntimeTypeHandle myRTHFromObject = Type.GetTypeHandle(myClass1);
        // Get the RuntimeTypeHandle from a type.
        RuntimeTypeHandle myRTHFromType = (MyClass1.class.ToType()).
            get_TypeHandle();

        Console.WriteLine("myRTHFromObject.Value: {0}", myRTHFromObject.
            get_Value());
        Console.WriteLine("myRTHFromObject.Type: {0}", myRTHFromObject.
            GetType());
        Console.WriteLine("myRTHFromType.Value: {0}", myRTHFromType.
            get_Value());
        Console.WriteLine("myRTHFromType.Type: {0}", myRTHFromType.
            GetType());
    }//main 
} //MyClass2

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