Question

我在VS2010中使用C＃的服务器客户端程序，其中客户端正在向服务器发送文件，服务器用另一个文件响应客户端。我想要的是让我的服务器继续使用我正在使用的功能

IPAddress[] ipAddress = Dns.GetHostAddresses("MRD044");
for (int i = 0; i < ipAddress.Length; i++)
{
    if (ipAddress[i].AddressFamily == AddressFamily.InterNetwork)
    {
        ipEnd = new IPEndPoint(ipAddress[i], 5656);
        sock = new Socket(AddressFamily.InterNetwork, SocketType.Stream, ProtocolType.IP);
        sock.Bind(ipEnd);
     }
 }
 curMsg = "Starting...";
 Console.WriteLine(curMsg);
 sock.Listen(10);
 curMsg = "Running and waiting to receive file.";

现在我想运行执行服务器端接收功能的getFile（）函数，仅在客户端将文件发送到服务器时运行。喜欢：

if(clientSendingFile())
{
    getFile();
}
else
{}

致电sock.Listen(10)后，请致电Accept方法等待传入连接：

Socket clientsocket = sock.Accept();

然后您对clientsocket的实现可能如下所示：

// pseudo-code - I might have a missed a C# thing or two...
void getFile()
{

  byte [] buffer = new byte[1000];


  while (true)
  {
      int count = -1;
      try
      {
          count = clientsock.Receive(buffer);
          // write count bytes into the file - however you are doing that
      }
      catch(Exception e)
      {
           // error
           count = -1;
           break;
      }
  }

如何识别客户端是否在VS2010中使用C＃向服务器发送文件？
