问题描述
我要写一个服务程序，需要用socket建立TCP的长连接来侦听客户端需要向客户端接收和发送数据，求教各位大大！~小弟刚接触通讯，菜鸟一个，能否请各位给我一个代码实例让我参考，谢谢了！~
解决方案
解决方案二：
与客户端进行心跳，自己去google
解决方案三：
看看c#socket通讯吧，很简单的东西了
解决方案四：
小弟刚接触通讯，很多东西都不明白请各位大大给个关键代码，指点一下，不胜感激！~诚心请教啦！~
解决方案五：
贴代码还不如自己先搜集资料学习google/baidu。再提出更具体的问题来。
解决方案六：
你去在资源里下个anysocket的例子，很简单的。
解决方案七：
#region接受连接voidAcceptCallBack(IAsyncResultar){Sockets=(Socket)ar.AsyncState;if(s==null){return;}SocketworkSocket=s.EndAccept(ar);if(workSocket==null||stoped){return;}allDone.Set();IPEndPointremoteHost=workSocket.RemoteEndPointasIPEndPoint;stringserverIP=remoteHost.Address.ToString();onAccecpt(serverIP);//首先取flag标志if(workSocket==null||stoped){return;}if(workSocket.Poll(-1,SelectMode.SelectRead)){StateObjecto=newStateObject();o.queue.Clear();o.workSocket=workSocket;intport=remoteHost.Port;serverIP=remoteHost.Address.ToString()+":"+port;workSocket.BeginReceive(buffer,0,buffer.Length,SocketFlags.None,newAsyncCallback(ReceiveCallBack),o);}}#endregionThreadmessageThread;#region接受消息voidReceiveCallBack(IAsyncResultar){receiveDone.Reset();StateObjecto=ar.AsyncStateasStateObject;SocketworkSocket=o.workSocket;this.workSocket=workSocket;IPEndPointremoteHost=workSocket.RemoteEndPointasIPEndPoint;intport=remoteHost.Port;stringserverIP=remoteHost.Address.ToString()+":"+port;if(workSocket==null||stoped){return;}intpos=workSocket.EndReceive(ar);if(pos>0){for(inti=0;i<pos;i++){o.queue.Enqueue(buffer[i]);}if(pos==bufferSize){workSocket.BeginReceive(buffer,0,buffer.Length,SocketFlags.None,newAsyncCallback(ReceiveCallBack),o);}else{//读取结束//得到接受到全部数据流if(o.queue.Count>0){ProcessDataprocessData=newProcessData();processData.MessageQueue=MessageHelper.GetMessages(o.queue);processData.ip=serverIP;processData.stateObject=o;MessageQueue.Enqueue(processData);if(messageThread==null){messageThread=newThread(newThreadStart(Process));messageThread.IsBackground=true;messageThread.Start();}}o.queue.Clear();if(workSocket.Poll(-1,SelectMode.SelectRead)){workSocket.BeginReceive(buffer,0,buffer.Length,SocketFlags.None,newAsyncCallback(ReceiveCallBack),o);}}}}#endregion
解决方案八：
如果要编写相对简单的应用程序，而且不需要最高的性能，则可以考虑使用TcpClient、TcpListener和UdpClient。这些类为Socket通信提供了更简单、对用户更友好的接口。
解决方案九：
usingSystem;usingSystem.Collections.Generic;usingSystem.Linq;usingSystem.Text;usingSystem.Net;usingSystem.Net.Sockets;namespace服务器{classProgram{staticvoidMain(string[]args){IPAddressip=IPAddress.Parse("127.0.0.1");TcpListenerlistener=newTcpListener(ip,8001);listener.Start();Console.WriteLine("服务器已启动，端口号为：8001");Console.WriteLine("服务器的网络地址为:{0}",listener.LocalEndpoint);Console.WriteLine("等待连接......");Sockets=listener.AcceptSocket();Console.WriteLine("连接来自:{0}",s.RemoteEndPoint);byte[]b=newbyte[1024];intcount=s.Receive(b);StringstrReceive=String.Empty;for(inti=0;i<count;i++){strReceive+=b[i];}Console.WriteLine("客户端发送过来的信息为:{0}",strReceive);ASCIIEncodingasen=newASCIIEncoding();s.Send(asen.GetBytes("ServerhaveReceive"));s.Close();listener.Stop();Console.ReadLine();}}}
