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：
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：
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 ();
}
}
}
希望本文所述对大家的C#程序设计有所帮助。
