Visual C# 2005中编写Socket网络程序(2)

综合运用以上阐述的使用Visual C#进行Socket网络程序开发的知识,下面的程序是一个简单的Socket通讯实例,client向server发送一段测试字符串,server接收并显示出来,给予client成功相应。

//client端
using System;
using System.Text;
using System.IO;
using System.Net;
using System.Net.Sockets;
namespace socketsample
{
 class Class1
 {
  static void Main()
  {
   try
   {
    int port = 2000;
    string host = "127.0.0.1";
    IPAddress ip = IPAddress.Parse(host);
    IPEndPoint ipe = new IPEndPoint(ip, port);
    Socket c = new Socket(AddressFamily.InterNetwork, SocketType.Stream, ProtocolType.Tcp);
    c.Connect(ipe);
    string sendStr = "hello!This is a socket test";
    byte[] bs = Encoding.ASCII.GetBytes(sendStr);
    c.Send(bs, bs.Length, 0);
    string recvStr = "";
    byte[] recvBytes = new byte[1024];
    int bytes;
    bytes = c.Receive(recvBytes, recvBytes.Length, 0);
    recvStr += Encoding.ASCII.GetString(recvBytes, 0, bytes);
    Console.WriteLine(recvStr);
    c.Close();
   }
   catch (ArgumentNullException e)
   {
    Console.WriteLine("ArgumentNullException: {0}", e);
   }
   catch (SocketException e)
   {
    Console.WriteLine("SocketException: {0}", e);
   }
   Console.ReadLine();
  }
 }
}
//server端
using System;
using System.Text;
using System.IO;
using System.Net;
using System.Net.Sockets;
namespace Project1
{
 class Class2
 {
  static void Main()
  {
   try
   {
    int port = 2000;
    string host = "127.0.0.1";
    IPAddress ip = IPAddress.Parse(host);
    IPEndPoint ipe = new IPEndPoint(ip, port);
    Socket s = new Socket(AddressFamily.InterNetwork, SocketType.Stream, ProtocolType.Tcp);
    s.Bind(ipe);
    s.Listen(0);
    Socket temp = s.Accept();
    string recvStr = "";
    byte[] recvBytes = new byte[1024];
    int bytes;
    bytes = temp.Receive(recvBytes, recvBytes.Length, 0);
    recvStr += Encoding.ASCII.GetString(recvBytes, 0, bytes);
    Console.WriteLine(recvStr);
    string sendStr = "Ok!Sucess!";
    byte[] bs = Encoding.ASCII.GetBytes(sendStr);
    temp.Send(bs, bs.Length, 0);
    temp.Shutdown(SocketShutdown.Both);
    temp.Close();
    s.Shutdown(SocketShutdown.Both);
    s.Close();
   }
   catch (ArgumentNullException e)
   {
    Console.WriteLine("ArgumentNullException: {0}", e);
   }
   catch (SocketException e)
   {
    Console.WriteLine("SocketException: {0}", e);
   }
   Console.ReadLine();
  }
 }
}

  以上程序在VS Express 2005 .Net2.0环境下测试通过。
