将内容过程中常用的内容段备份一次，如下资料是关于C#通过Socket在网络间发送和接收图片的演示的内容，希望能对码农们有帮助。

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)
{
Socket sListen = new Socket (AddressFamily.InterNetwork, SocketType.Stream, ProtocolType.Tcp);

        IPAddress IP = IPAddress.Parse ("127.0.0.1");IPEndPoint IPE = new IPEndPoint (IP, 4321);sListen.Bind (IPE);Console.WriteLine ("Service is listening ...");sListen.Listen (2);while (true){Socket clientSocket;try{clientSocket = sListen.Accept ();}catch{throw;}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 ();GC.ReRegisterForFinalize (fileinfo);GC.ReRegisterForFinalize (fs);return buf;}}

}

客户端接收和保存图片的代码

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)
{
Socket S = new Socket (AddressFamily.InterNetwork, SocketType.Stream, ProtocolType.Tcp);

        IPAddress IP = IPAddress.Parse ("127.0.0.1");IPEndPoint IPE = new IPEndPoint (IP, 4321);Console.WriteLine ("started connection service ....");s.Connect (IPE);byte[] buffer = new byte[1000000];s.Receive (buffer, buffer.Length, SocketFlags.None);Console.WriteLine ("Receive success");FileStream fs =  File.Create ("1.jpg");fs.Write (buffer, 0, buffer.Length);fs.Close ();Console.ReadKey ();}
}

}
