Ejemplos

El ejemplo de código siguiente muestra cómo activar un objeto en otro AppDomain, recuperar el proxy con el Unwrap método y utilizar el proxy para tener acceso al objeto remoto.The following code example demonstrates how to activate an object in another AppDomain, retrieve a proxy to it with the Unwrap method, and use the proxy to access the remote object.

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

Notas a los autores de las llamadas

Un ObjectHandle tiene un acceso remoto MarshalByRefObject cuyo seguimiento se realiza mediante el servicio de duración de comunicación remota.A ObjectHandle is a remoted MarshalByRefObject that is tracked by the remoting lifetime service. Una llamada al método actual puede fallar si la duración de la concesión en el ObjectHandle expira.A call to the current method can fail if the lifetime lease on the ObjectHandle expires.
