大佬教程收集整理的这篇文章主要介绍了C# Socket系列2 TcpListener & TcpClient，大佬教程大佬觉得挺不错的，现在分享给大家，也给大家做个参考。
这两个类是对socket的进一步封装
服务端
1 class Program 2 { 3 static void Main(String[] args) 4 { 5 TcpListener listener = null; 6 listener = new TcpListener(Ipaddress.Parse("127.0.0.1"),9999); 7 listener.Start(); 8 listener.beginAcceptTcpClient(new AsyncCallBACk(acceptCall),listener); 9 Console.ReadKey(); 10 } 11 12 private static void acceptCall(IAsyncResult ar) 13 { 14 TcpListener lstn = ar.AsyncState as TcpListener; 15 TcpClient client = lstn.EndAcceptTcpClient(ar); 16 Task.Run(() => { 17 String host = client.Client.RemoteEndPoint.ToString(); 18 NetworkStream stream = client.GetStream(); 19 try 20 { 21 while (true) 22 { 23 byte[] buffer = new byte[sizeof(int)]; 24 stream.Read(buffer,0,sizeof(int)); 25 int len = BitConverter.ToInt32(buffer,0); 26 buffer = new byte[len]; 27 stream.Read(buffer,0,len); 28 String resMsg = Encoding.UTF8.GetString(buffer); 29 if (resMsg == "Q") 30 { 31 String message = "客户端" + host + "发出退出请求"; 32 Console.WriteLine(messagE); 33 break; 34 } 35 else 36 { 37 String message = "收到" + host + "发的消息：" + resMsg; 38 Console.WriteLine(messagE); 39 } 40 } 41 } 42 catch (Exception E) 43 { 44 45 Console.WriteLine(e.messagE); 46 } 47 stream.Close(); 48 client.Close(); 49 }); 50 51 lstn.beginAcceptTcpClient(new AsyncCallBACk(acceptCall),lstn); 52 } 53 54 55 }
客户端
class Program
{
static TcpClient client;
static void Main(String[] args)
{
client = new TcpClient("127.0.0.1",9999);
while (true)//发送
{
String msg = Console.ReadLine();
if (msg == "Q")
{
Sendmessage(msg);
break;
}
else
Sendmessage(msg);
}
}
private static void Sendmessage(String msg)
{
if (client == null) return;
if (client.Connected == falsE) return;
byte[] data = Encoding.UTF8.GetBytes(msg);
int len = data.Length;
byte[] buffer = BitConverter.GetBytes(len);
client.GetStream().Write(buffer,sizeof(int));
client.GetStream().Write(data,data.Length);
}
}
以上是大佬教程为你收集整理的C# Socket系列2 TcpListener & TcpClient全部内容，希望文章能够帮你解决C# Socket系列2 TcpListener & TcpClient所遇到的程序开发问题。
