服務(wù)器端：不斷接收客戶端的輸入

??????????? //TcpListener listener = new TcpListener(portNum); //根據(jù)VS2005 MSDN 此方法已經(jīng)過(guò)時(shí)，不再使用

??????????? // IPEndPoint類(lèi)將網(wǎng)絡(luò)標(biāo)識(shí)為IP地址和端口號(hào)

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

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

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

/* 如果不是文件的話，可以在內(nèi)存中存儲(chǔ)一個(gè)臨時(shí)內(nèi)存流，以便后續(xù)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);

*/
