How to: Build a Remotable Type 

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.

NoteNote

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.

   Public Class RemotableType
      Inherits MarshalByRefObject
    …
End Class
public class RemotableType : MarshalByRefObject
{
    …
}

Example

' RemotableType.vb
Imports System

Public Class RemotableType
   Inherits MarshalByRefObject 
   Public Function SayHello() As String
      Console.WriteLine("RemotableType.SayHello() was called!")
      Return "Hello, world"
   End Function 
End Class 
// RemotableType.cs
using System;
public class RemotableType : MarshalByRefObject
{
    public string SayHello()
    {
        Console.WriteLine("RemotableType.SayHello() was called!");
        return "Hello, world";
    }
}
