客戶端：實現向服務器發送文件

using System.Net;

?

namespace tcpclient

{

??? class tcpclient

??? {

??????? private static int portNum = 11000;

??????? static void Main(string[] args)

??????? {

????????? ??//第一步：讀取文件

??????????? Console.WriteLine("本程序實現向服務器發送文件...");

??????????? FileStream fs = File.Open("http://www.cnblogs.com/img.gif", FileMode.Open);

??????????? byte[] buffer = new byte[fs.Length];

??????????? fs.Read(buffer, 0, (int)fs.Length);

??????????? fs.Close();

??????????? //第二步：發送文件

??????????? try

??????????????? NetworkStream ns = client.GetStream();

??????????????? ns.Write(buffer, 0, buffer.Length);

服務器端：不斷接收客戶端的輸入

using System;

using System.Collections.Generic;

using System.Text;

using System.IO;

using System.Net.Sockets;

using System.Net;

?

namespace tcpfile

{

??? class tcpserver

??? {

??????? private const int portNum = 11000;

??????? static void Main(string[] args)

??????? {

??????????? bool done = false;

??????????? //TcpListener listener = new TcpListener(portNum); //根據VS2005 MSDN 此方法已經過時，不再使用

??????????? // IPEndPoint類將網絡標識為IP地址和端口號

??????????? TcpListener listener = new TcpListener(new IPEndPoint(IPAddress.Any, portNum));

??????????? listener.Start();

???????????while (!done)

??????????? {

??????????????? Console.Write("Waiting for connection...");

??????????????? TcpClient client = listener.AcceptTcpClient();

??????????????? Console.WriteLine("Connection accepted.");

??????????????? NetworkStream ns = client.GetStream();

??????????????

??????????????? byte[] tempBuffer = new byte[4096];

??????????????? FileStream fs = File.Open(new Random().Next().ToString() + ".gif", FileMode.CreateNew);

??????????????? int bytesRead = 0;

??????????????? do

?????????? ?????{

??????????????????? bytesRead = ns.Read(tempBuffer, 0, 4096);

??????????????????? fs.Write(tempBuffer, 0, bytesRead);

??????????????? }while (bytesRead > 0);

???????????????

??????????????? fs.Close();

??????????????? client.Close();

????????????? ??Console.WriteLine("file accepted.");

??????????????

??????????? }

??????????? listener.Stop();

??????? }

?

??? }

}

/* 如果不是文件的話，可以在內存中存儲一個臨時內存流，以便后續處理，如：賦給Image控件，壓縮流等。

?*?一種典型的從客戶端讀取流的方法

?? NetworkStream clientStreams = client.GetStream();

?? int bufferSize = 4096;

?? byte[] responseBuffer = new byte[bufferSize];

?? MemoryStream memStream = new MemoryStream();

?? int bytesRead = 0;

?? do

?? {

?????? bytesRead = clientStream.Read(responseBuffer, 0, bufferSize);

?????? memStream.Write(responseBuffer, 0, bytesRead);

??? } while (bytesRead > 0);

*/

?

/*

?* 這種模式，是不被 NetworkStream clientStreams = client.GetStream(); 所支持的

byte[] buffer = new byte[clientStreams.Length];

clientStream.Read(buffer, 0, (int)fs.Length);

*/
