How to: Build a Remotable Type
This topic is specific to a legacy technology that is retained for backward compatibility with existing applications and is not recommended for new development. Distributed applications should now be developed using the Windows Communication Foundation (WCF).
To enable objects in other application domains to use an instance of your class, your class must inherit from MarshalByRefObject. The following procedure describes how to create a basic object that can be created and invoked from objects executing in another application domain.
|See How to: Compile and Run a Basic Remoting Application for complete instructions on how to build and run this sample.|
To build a remotable type
Define a class that derives from the MarshalByRefObject class.
Implement the methods and properties for that class as you would for a non-remotable type. A call is made to
Console.WriteLineto have the listener display a string. This is used later to demonstrate that the remote object was called.
Public Function SayHello() As String Console.WriteLine("RemotableType.SayHello() was called!") Return "Hello, world" End Function 'StringMethod
Create a directory named
remoting\typeand save the class as
RemotingType.vb, in the new directory. Open a command-prompt and navigate to the
remoting\typedirectory and type the following command:
