本文实例讲述了asp.net使用Socket.Send发送信息及Socket.SendFile传输文件的方法。分享给大家供大家参考，具体如下：

// Displays sending with a connected socket// using the overload that takes a buffer.public static int SendReceiveTest1(Socket server){ byte[] msg = Encoding.UTF8.GetBytes("This is a test"); byte[] bytes = new byte[256]; try { // Blocks until send returns. int i = server.Send(msg); Console.WriteLine("Sent {0} bytes.", i); // Get reply from the server. i = server.Receive(bytes); Console.WriteLine(Encoding.UTF8.GetString(bytes)); } catch (SocketException e) { Console.WriteLine("{0} Error code: {1}.", e.Message, e.ErrorCode); return (e.ErrorCode); } return 0;}// Establish the local endpoint for the socket.IPHostEntry ipHost = Dns.GetHostEntry(Dns.GetHostName());IPAddress ipAddr = ipHost.AddressList[0];IPEndPoint ipEndPoint = new IPEndPoint(ipAddr, 11000);// Create a TCP socket.Socket client = new Socket(AddressFamily.InterNetwork, SocketType.Stream, ProtocolType.Tcp);// Connect the socket to the remote endpoint.client.Connect(ipEndPoint);// There is a text file test.txt located in the root directory.string fileName = "C:\\test.txt";// Send file fileName to remote deviceConsole.WriteLine("Sending {0} to the host.", fileName);client.SendFile(fileName);// Release the socket.client.Shutdown(SocketShutdown.Both);client.Close();
