遠端開發分散式C#程式設計例項

分散式C#程式設計

從客戶端到服務端的遠端網路通訊，傳送訊息並返回遠端訊息。
遠端物件(RemoteTest)C# 類庫程式碼部分:

--&gtusing 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元件中的 TestLoader 類繼承了 System.MarshalByRefObject 類，便讓客戶端能訪問該遠端物件了。


服務端(Server)命令列應用程式程式碼部分:

--&gtusing 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：引用新增元件：System.Runtime.Remoting(下同)。

客戶端(Client)命令列應用程式程式碼部分:

--&gtusing 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);
        }
    }
}

這裡對new 管道宣告的那兩行已略寫。

 

程式除錯：啟動Server後，再啟動Client。輸入值後關閉Client，值便在Server中顯示。
