RuntimeTypeHandle Structure

Represents a type using an internal metadata token.

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

[SerializableAttribute]
[ComVisibleAttribute(true)]
public struct RuntimeTypeHandle : ISerializable

The RuntimeTypeHandle type exposes the following members.

  NameDescription
Public propertyValueGets a handle to the type represented by this instance.
Top

  NameDescription
Public methodSupported by the XNA FrameworkEquals(Object)Indicates whether the specified object is equal to the current RuntimeTypeHandle structure. (Overrides ValueType.Equals(Object).)

In XNA Framework, this member is overridden by Equals(Object).
Public methodSupported by Portable Class LibraryEquals(RuntimeTypeHandle)Indicates whether the specified RuntimeTypeHandle structure is equal to the current RuntimeTypeHandle structure.
Protected methodSupported by the XNA FrameworkSupported by Portable Class LibraryFinalizeAllows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection. (Inherited from Object.)
Public methodSupported by the XNA FrameworkGetHashCodeReturns the hash code for the current instance. (Overrides ValueType.GetHashCode().)

In XNA Framework, this member is overridden by GetHashCode().
Public methodGetModuleHandleGets a handle to the module that contains the type represented by the current instance.
Public methodGetObjectDataPopulates a SerializationInfo with the data necessary to deserialize the type represented by the current instance.
Public methodSupported by the XNA FrameworkSupported by Portable Class LibraryGetTypeGets the Type of the current instance. (Inherited from Object.)
Protected methodSupported by the XNA FrameworkSupported by Portable Class LibraryMemberwiseCloneCreates a shallow copy of the current Object. (Inherited from Object.)
Public methodSupported by the XNA FrameworkSupported by Portable Class LibraryToStringReturns the fully qualified type name of this instance. (Inherited from ValueType.)

In XNA Framework 3.0, this member is inherited from Object.ToString().


In Portable Class Library Portable Class Library, this member is inherited from Object.ToString().

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.


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("\nmyRTHFromObject.Value:  {0}", myRTHFromObject.Value);
        Console.WriteLine("myRTHFromObject.GetType():  {0}", myRTHFromObject.GetType());
        Console.WriteLine("Get the type back from the handle...");
        Console.WriteLine("Type.GetTypeFromHandle(myRTHFromObject):  {0}", 
            Type.GetTypeFromHandle(myRTHFromObject));

        Console.WriteLine("\nmyRTHFromObject.Equals(myRTHFromType):  {0}", 
            myRTHFromObject.Equals(myRTHFromType));

        Console.WriteLine("\nmyRTHFromType.Value:  {0}", myRTHFromType.Value);
        Console.WriteLine("myRTHFromType.GetType():  {0}", myRTHFromType.GetType());
        Console.WriteLine("Get the type back from the handle...");
        Console.WriteLine("Type.GetTypeFromHandle(myRTHFromType):  {0}", 
            Type.GetTypeFromHandle(myRTHFromType));
    }
}

/* This code example produces output similar to the following:

myRTHFromObject.Value:  799464
myRTHFromObject.GetType():  System.RuntimeTypeHandle
Get the type back from the handle...
Type.GetTypeFromHandle(myRTHFromObject):  MyClass1

myRTHFromObject.Equals(myRTHFromType):  True

myRTHFromType.Value:  799464
myRTHFromType.GetType():  System.RuntimeTypeHandle
Get the type back from the handle...
Type.GetTypeFromHandle(myRTHFromType):  MyClass1
