JScript

    handle : RuntimeTypeHandle
) : Type

Parameters

handle: Type: System..::.RuntimeTypeHandle
The RuntimeTypeHandle object that refers to the type.

Return Value

Type: System..::.Type

The type referenced by the specified RuntimeTypeHandle, or nullNothingnullptra null reference (Nothing in Visual Basic) if the Value property of handle is nullNothingnullptra null reference (Nothing in Visual Basic).

If the requested type is non-public and the caller does not have ReflectionPermission to reflect non-public objects outside the current assembly, this method returns nullNothingnullptra null reference (Nothing in Visual Basic).

Examples

The following example uses the GetTypeFromHandle method to get a Type object from a RuntimeTypeHandle provided by the GetTypeHandle method.

Visual Basic

   Dim myClass1 As New MyClass1()
   ' Get the type referenced by the specified type handle.
   Dim myClass1Type As Type = Type.GetTypeFromHandle(Type.GetTypeHandle(MyClass1))
   Console.WriteLine(("The Names of the Attributes :" + myClass1Type.Attributes.ToString()))
End Sub 'Main

        MyClass1 myClass1 = new MyClass1();
         // Get the type referenced by the specified type handle.
        Type myClass1Type = Type.GetTypeFromHandle(Type.GetTypeHandle(myClass1));
        Console.WriteLine("The Names of the Attributes :"+myClass1Type.Attributes);

Visual C++

MyClass1^ myClass1 = gcnew MyClass1;
// Get the type referenced by the specified type handle.
Type^ myClass1Type = Type::GetTypeFromHandle( Type::GetTypeHandle( myClass1 ) );
Console::WriteLine( "The Names of the Attributes : {0}", myClass1Type->Attributes );

MyClass1 myClass1 =  new MyClass1();
// Get the type referenced by the specified type handle.
Type myClass1Type = Type.GetTypeFromHandle(Type.GetTypeHandle(myClass1));
Console.WriteLine("The Names of the Attributes :" + myClass1Type.
    get_Attributes());
