creates three instances of the same type. A local and two remote proxies to object instances are constructed:

   
 

using System;
using System.Reflection;
using System.Runtime.Remoting;


class MyClass {
    public void MethodA(DateTime dt) {
        Console.WriteLine("MethodA invoked at " + dt.ToLongTimeString());
    }
}

class Starter {

    static void Main() {
        CreateLocal();
        CreateRemote1();
        CreateRemote2();
    }

    static void CreateLocal() {
        object obj = Activator.CreateInstance(typeof(MyClass));
        ((MyClass)obj).MethodA(DateTime.Now);
    }

    static void CreateRemote1() {
        ObjectHandle hObj = Activator.CreateInstance("library","MyClass");
        object obj = hObj.Unwrap();

        MethodInfo method = obj.GetType().GetMethod("MethodA");
        method.Invoke(obj, new object[1] { DateTime.Now });
    }

    static void CreateRemote2() {
        AppDomain domain = AppDomain.CurrentDomain;
        object obj = domain.CreateInstanceFromAndUnwrap("library.dll","MyClass");
        MethodInfo method = obj.GetType().GetMethod("MethodA");
        method.Invoke(obj, new object[1] { DateTime.Now });
    }
}
