Örnekler

Aşağıdaki kod örneği, başka AppDomainbir içindeki bir nesneyi etkinleştirmeyi, yöntemiyle Unwrap ona bir proxy almayı ve uzak nesneye erişmek için proxy'yi kullanmayı gösterir.

// Creates an instance of MyType defined in the assembly called ObjectHandleAssembly.
ObjectHandle^ obj = domain->CreateInstance( "ObjectHandleAssembly", "MyType" );

// Unwraps the proxy to the MyType object created in the other AppDomain.
MyType^ testObj = dynamic_cast<MyType^>(obj->Unwrap());
if ( RemotingServices::IsTransparentProxy( testObj ) )
   Console::WriteLine( "The unwrapped object is a proxy." );
else
   Console::WriteLine( "The unwrapped object is not a proxy!" );

Console::WriteLine( "" );
Console::Write( "Calling a method on the object located in an AppDomain with the hash code " );
Console::WriteLine( testObj->GetAppDomainHashCode() );

// Creates an instance of MyType defined in the assembly called ObjectHandleAssembly.
ObjectHandle obj = domain.CreateInstance("ObjectHandleAssembly", "MyType");

// Unwrapps the proxy to the MyType object created in the other AppDomain.
MyType testObj = (MyType)obj.Unwrap();

if(RemotingServices.IsTransparentProxy(testObj))
   Console.WriteLine("The unwrapped object is a proxy.");
else
   Console.WriteLine("The unwrapped object is not a proxy!");

Console.WriteLine("");
Console.Write("Calling a method on the object located in an AppDomain with the hash code ");
Console.WriteLine(testObj.GetAppDomainHashCode());

' Creates an instance of MyType defined in the assembly called ObjectHandleAssembly.
Dim obj As ObjectHandle = domain.CreateInstance("ObjectHandleAssembly", "MyType")

' Unwrapps the proxy to the MyType object created in the other AppDomain.
Dim testObj As MyType = CType(obj.Unwrap(), MyType)

If RemotingServices.IsTransparentProxy(testObj) Then
   Console.WriteLine("The unwrapped object is a proxy.")
Else
   Console.WriteLine("The unwrapped object is not a proxy!")
End If 
Console.WriteLine("")
