Notas para los llamadores
Un ObjectHandle es un MarshalByRefObject remoto cuyo seguimiento se realiza mediante el servicio de duración remoto. Una llamada al método actual puede fallar si vence el período de duración de ObjectHandle.
En el siguiente ejemplo de código se muestra cómo activar un objeto en otro AppDomain, recuperar el proxy con el método Unwrap y utilizar el proxy para tener acceso al objeto remoto.
' 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("")
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.
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() );
