本文实例讲述了C#使用Socket实现发送和接收图片的方法。分享给大家供大家参考。具体如下:
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50 51 52 53 54 55 56 | using System; using System.Collections.Generic; using System.Text; using System.Net.Sockets; using System.Net; using System.IO; namespace ConsoleApplication1 { Class Program { static void Main (String[] args) { // 1. to create a socket Socket sListen = new Socket (AddressFamily.InterNetwork, SocketType.Stream, ProtocolType.Tcp); // 2. Fill IP IPAddress IP = IPAddress.Parse ( "127.0.0.1" ); IPEndPoint IPE = new IPEndPoint (IP, 4321); // 3. binding sListen.Bind (IPE); // 4. Monitor Console.WriteLine ( "Service is listening ..." ); sListen.Listen (2); // 5. loop to accept client connection requests while ( true ) { Socket clientSocket; try { clientSocket = sListen.Accept (); } catch { throw ; } // send data to the client //clientSocket.Send (Encoding.Unicode.GetBytes ("I am a server, you there?? !!!!")); // send the file byte [] buffer = ReadImageFile ( "1.jpg" ); clientSocket.Send (buffer, buffer.Length, SocketFlags.None); Console.WriteLine ( "Send success!" ); } } private static byte [] ReadImageFile (String img) { FileInfo fileinfo = new FileInfo (img); byte [] buf = new byte [fileInfo.Length]; FileStream fs = new FileStream (img, FileMode.Open, FileAccess.Read); fs.Read (buf, 0, buf.Length); fs.Close (); //fileInfo.Delete (); GC.ReRegisterForFinalize (fileinfo); GC.ReRegisterForFinalize (fs); return buf; } } } |
客户端接收和保存图片的代码如下:
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 | using System; using System.Collections.Generic; using System.Text; using System.Net.Sockets; using System.Net; using System.IO; namespace ConsoleApplication2 { Class Program { static void Main (String[] args) { // 1. to create a socket Socket S = new Socket (AddressFamily.InterNetwork, SocketType.Stream, ProtocolType.Tcp); // 2. fill in the remote IP IPAddress IP = IPAddress.Parse ( "127.0.0.1" ); IPEndPoint IPE = new IPEndPoint (IP, 4321); Console.WriteLine ( "started connection service ...." ); // 3. connect to the server s.Connect (IPE); // 4. receive data byte [] buffer = new byte [1000000]; s.Receive (buffer, buffer.Length, SocketFlags.None); //var Msg = Encoding.Unicode.GetString (buffer); //Console.WriteLine ("received message: (0)", msg); Console.WriteLine ( "Receive success" ); FileStream fs = File.Create ( "1.jpg" ); fs.Write (buffer, 0, buffer.Length); fs.Close (); Console.ReadKey (); } } } |
