下面看一個完整的例子,client向server發送一段測試字符串,server接收並顯示出來,給予clIEnt成功響應。
//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);//把ip和端口轉化為IPEndPoint實例 Socket c = new Socket(AddressFamily.InterNetwork, SocketType.Stream, ProtocolType.Tcp);//創建一個Socket Console.WriteLine("Conneting..."); c.Connect(ipe);//連接到服務器 string sendStr = "hello!This is a socket test"; byte[] bs = Encoding.ASCII.GetBytes(sendStr); Console.WriteLine("Send Message"); c.Send(bs, bs.Length, 0);//發送測試信息 string recvStr = ""; byte[] recvBytes = new byte[1024]; int bytes; bytes = c.Receive(recvBytes, recvBytes.Length, 0);//從服務器端接受返回信息 recvStr += Encoding.ASCII.GetString(recvBytes, 0, bytes); Console.WriteLine("ClIEnt Get Message:{0}", recvStr);//顯示服務器返回信息 c.Close(); } catch (ArgumentNullException e) { Console.WriteLine("ArgumentNullException: {0}", e); } catch (SocketException e) { Console.WriteLine("SocketException: {0}", e); } Console.WriteLine("Press Enter to Exit"); Console.ReadLine(); } } }
