Examples

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

Type.GetTypeFromHandle(myRTHFromObject): MyClass1

myRTHFromObject.Equals(myRTHFromType): True
