C#:Socket通信

之前一直想自己搞把C#的Socket代码，一直没有下手，今晚终于实践了一把。现把流程编写出来，以备后用。

很简单的源码。

工具：Vs2010

建立项目：C# 控制台应用程序

Server代码

using System; 

using System.Collections.Generic; 

using System.Linq; 

using System.Text; 
//添加Socket类 

using System.Net; 

using System.Net.Sockets; 

namespace SockeConsoleServer 
{ 

    class Program 

    { 

        static void Main(string[] args) 

        { 

            int port = 2000; 

            string host = "127.0.0.1"; 

            //创建终结点 

            IPAddress ip = IPAddress.Parse(host); 

            IPEndPoint ipe = new IPEndPoint(ip,port);  

            //创建Socket并开始监听 

            Socket s = new Socket(AddressFamily.InterNetwork, SocketType.Stream, ProtocolType.Tcp); //创建一个Socket对象，如果用UDP协议，则要用SocketTyype.Dgram类型的套接字 

            s.Bind(ipe);    //绑定EndPoint对象(2000端口和ip地址) 

            s.Listen(0);    //开始监听 

            Console.WriteLine("等待客户端连接"); 

            //接受到Client连接，为此连接建立新的Socket，并接受消息 

            Socket temp = s.Accept();   //为新建立的连接创建新的Socket 

            Console.WriteLine("建立连接"); 

            string recvStr = ""; 

            byte[] recvBytes = new byte[1024]; 

            int bytes; 

            bytes = temp.Receive(recvBytes,recvBytes.Length,0); //从客户端接受消息 

            recvStr += Encoding.ASCII.GetString(recvBytes, 0, bytes); 

            //给Client端返回信息 

            Console.WriteLine("server get message:{0}",recvStr);    //把客户端传来的信息显示出来 

            string sendStr = "ok!Client send message successful!"; 

            byte[] bs = Encoding.ASCII.GetBytes(sendStr); 

            temp.Send(bs,bs.Length,0);  //返回信息给客户端 

            temp.Close(); 

            s.Close(); 

            Console.ReadLine(); 

        } 

    } 
}

Client代码：

using System; 

using System.Collections.Generic; 

using System.Linq; 

using System.Text; 
//添加用于Socket的类 

using System.Net; 

using System.Net.Sockets; 

namespace SocketConsoleClient 
{ 

    class Program 

    { 

        static void Main(string[] args) 

        { 

            try

            { 

                int port = 2000; 

                string host = "127.0.0.1"; 

                //创建终结点EndPoint 

                IPAddress ip = IPAddress.Parse(host); 

                IPEndPoint ipe = new IPEndPoint(ip, port);   //把ip和端口转化为IPEndPoint的实例 

                //创建Socket并连接到服务器 

                Socket c = new Socket(AddressFamily.InterNetwork, SocketType.Stream, ProtocolType.Tcp);   //  创建Socket 

                Console.WriteLine("Connecting..."); 

                c.Connect(ipe); //连接到服务器 

                //向服务器发送信息 

                string sendStr = "Hello,this is a socket test"; 

                byte[] bs = Encoding.ASCII.GetBytes(sendStr);   //把字符串编码为字节 

                Console.WriteLine("Send message"); 

                c.Send(bs, bs.Length, 0); //发送信息 

                //接受从服务器返回的信息 

                string recvStr = ""; 

                byte[] recvBytes = new byte[1024]; 

                int bytes; 

                bytes = c.Receive(recvBytes, recvBytes.Length, 0);    //从服务器端接受返回信息 

                recvStr += Encoding.ASCII.GetString(recvBytes, 0, bytes); 

                Console.WriteLine("client get message:{0}", recvStr);    //回显服务器的返回信息 

                Console.ReadLine(); 

                //一定记着用完Socket后要关闭 

                c.Close(); 

            } 

            catch (ArgumentException e) 

            { 

                Console.WriteLine("argumentNullException:{0}", e); 

            } 

            catch (SocketException e) 

            { 

                Console.WriteLine("SocketException:{0}",e); 

            } 

        } 

    } 
}
