Esempio

Nell'esempio di codice seguente viene illustrato come attivare un oggetto in un altro AppDomain , come recuperare un proxy con il Unwrap metodo e come utilizzare il proxy per accedere all'oggetto 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())

Note per i chiamanti

Un ObjectHandle è un oggetto remoto MarshalByRefObject rilevato dal servizio di durata remota.A ObjectHandle is a remoted MarshalByRefObject that is tracked by the remoting lifetime service. Una chiamata al metodo corrente può avere esito negativo se il lease di durata ObjectHandle scade.A call to the current method can fail if the lifetime lease on the ObjectHandle expires.
