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
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
 */

Properties

Value

Gets a handle to the type represented by this instance.

Methods

Equals(Object)

Indicates whether the specified object is equal to the current RuntimeTypeHandle structure.

Equals(RuntimeTypeHandle)

Indicates whether the specified RuntimeTypeHandle structure is equal to the current RuntimeTypeHandle structure.

FromIntPtr(IntPtr)

Returns a new RuntimeTypeHandle object created from a handle to a RuntimeType.

GetHashCode()

Returns the hash code for the current instance.

GetModuleHandle()

Gets a handle to the module that contains the type represented by the current instance.

GetObjectData(SerializationInfo, StreamingContext)
Obsolete.

Populates a SerializationInfo with the data necessary to deserialize the type represented by the current instance.

ToIntPtr(RuntimeTypeHandle)

Returns the internal pointer representation of a RuntimeTypeHandle object.

Operators

Equality(Object, RuntimeTypeHandle)

Indicates whether an object and a RuntimeTypeHandle structure are equal.

Equality(RuntimeTypeHandle, Object)

Indicates whether a RuntimeTypeHandle structure is equal to an object.

Inequality(Object, RuntimeTypeHandle)

Indicates whether an object and a RuntimeTypeHandle structure are not equal.

Inequality(RuntimeTypeHandle, Object)

Indicates whether a RuntimeTypeHandle structure is not equal to an object.
