远程开发分布式C#编程实例

从客户端到服务端的远程网络通讯，发送消息并返回远程消息。
远程对象(RemoteTest)C# 类库代码部分:

using System;

namespace RemoteTest
{
   public class TestLoader : MarshalByRefObject
   {
        public TestLoader()
        {
            string stringWrite = "stor load.";
           Console.WriteLine(stringWrite);
        }
       public string sayHello(string msg)
       {
           Console.WriteLine("Message: { 0 } ", msg);
           Console.WriteLine("Welcome to Message send Systems");

           string stc = "Hello from remote";
           return stc;
        }
    }
}

RemoteTest组件中的 TestLoader 类继承了 System.MarshalByRefObject 类，便让客户端能访问该远程对象了。

服务端(Server)命令行应用程序代码部分:

using System;
using System.Runtime;
using System.Runtime.Remoting;
using System.Runtime.Remoting.Channels;
using System.Runtime.Remoting.Channels.Tcp;
using RemoteTest;

namespace Server
{
   public class Program
   {
       public static void Main(string[] args)
       {
           TcpServerChannel channel = new TcpServerChannel(9932);
           ChannelServ ices.RegisterChannel(channel, false);
           RemotingConfiguration.RegisterWellKnownServiceType(typeof(TestLoader),"TestLoader",WellKnownObjectMode.SingleCall);
           Console.WriteLine("Hello From Server");
           Console.ReadLine();
        }
    }
}

注：引用添加组件：System.Runtime.Remoting(下同)。

客户端(Client)命令行应用程序代码部分:

using System;
using System.Runtime.Remoting;
using System.Runtime.Remoting.Channels;
using System.Runtime.Remoting.Channels.Tcp;
using RemoteTest;

namespace Client
{
   public class ClassClient
   {
       public static void Main(string[] args)
       {
           string stringTcp = "tcp://localhost:9932/TestLoader";
           TestLoader loader = (TestLoader)Activator.GetObject(typeof(RemoteTest.TestLoader),stringTcp);
           string msg;
           Console.Write("Enter Message: ");
           msg = Console.ReadLine();
           Console.WriteLine("Message: {0}" + msg);
           string res = loader.sayHello(msg);
           Console.WriteLine(res);
        }
    }
}

这里对new 管道声明的那两行已略写。

 

程序调试：启动Server后，再启动Client。输入值后关闭Client，值便在Server中显示。
