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（）;
