学习技术知识一个好的方法是先动手，再深入，

给出一个最简单的Remoting程序示例（C#）如下：

Step1:创建类库（DLL）工程RemotingObjects，类Person代码如下：

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;

namespace RemotingObjects
{
    public interface IPerson
    {
        String getName(String name);

    }

    public class Person : MarshalByRefObject, IPerson
    {
        public Person()
        {
            Console.WriteLine("[Person]:Remoting Object 'Person' is activated.");
        }

        public String getName(String name)
        {
            return name;
        }
    }
}

Step2:创建控制台工程RemotingServer（添加项目引用RemotingObjects），类Server代码如下：

using System;
using System.Collections.Generic;
using System.Linq;
using System.Runtime.Remoting;
using System.Runtime.Remoting.Channels;
using System.Runtime.Remoting.Channels.Tcp;
using System.Text;
using System.Threading.Tasks;


namespace RemotingServer
{
    class Server
    {
        static void Main(string[] args)
        {
            TcpChannel channel = new TcpChannel(8080);
            ChannelServices.RegisterChannel(channel, false);
            RemotingConfiguration.RegisterWellKnownServiceType(typeof(RemotingObjects.Person), "RemotingPersonService", WellKnownObjectMode.SingleCall);

            System.Console.WriteLine("Server:Press Enter key to exit");
            System.Console.ReadLine();
        }
    }
}

Step3:创建控制台工程RemotingClient（添加项目引用RemotingObjects及必要类库），类Client代码如下：

（PS:正式应用开发，不需要也不应该直接引用RemotingObjects类库，而应该引用相关Remoting类的接口库。）

using RemotingObjects;
using System;
using System.Collections.Generic;
using System.Linq;
using System.Runtime.Remoting.Channels;
using System.Runtime.Remoting.Channels.Tcp;
using System.Text;
using System.Threading.Tasks;

namespace RemotingClient
{
    class Client
    {
        static void Main(string[] args)
        {
            TcpChannel channel = new TcpChannel();
            ChannelServices.RegisterChannel(channel, false);
            IPerson obj = (IPerson)Activator.GetObject(typeof(RemotingObjects.IPerson), "tcp://localhost:8080/RemotingPersonService");
            if (obj == null)
            {
                Console.WriteLine("Couldn't crate Remoting Object 'Person'.");
            }

            Console.WriteLine("Please enter your name：");
            String name = Console.ReadLine();
            try
            {
                Console.WriteLine(obj.getName(name));
            }
            catch (System.Net.Sockets.SocketException e) {
                Console.WriteLine(e.ToString());
            }
                Console.ReadLine();
        }
    }
}

Step4:运行编译出的EXE：RemotingServer.exe和RemotingClient.exe，查看运行结果。
