There's a black hole in my server (TcpClient, TcpListener)
- by Matías
Hi,
I'm trying to build a server that will receive files sent by clients over a network. If the client decides to send one file at a time, there's no problem, I get the file as I expected, but if it tries to send more than one I only get the first one.
Here's the server code:
I'm using one Thread per connected client
public void ProcessClients()
{
while (IsListening)
{
ClientHandler clientHandler = new ClientHandler(listener.AcceptTcpClient());
Thread thread = new Thread(new ThreadStart(clientHandler.Process));
thread.Start();
}
}
The following code is part of ClientHandler class
public void Process()
{
while (client.Connected)
{
using (MemoryStream memStream = new MemoryStream())
{
int read;
while ((read = client.GetStream().Read(buffer, 0, buffer.Length)) > 0)
{
memStream.Write(buffer, 0, read);
}
if (memStream.Length > 0)
{
Packet receivedPacket = (Packet)Tools.Deserialize(memStream.ToArray());
File.WriteAllBytes(Path.Combine(Environment.GetFolderPath(Environment.SpecialFolder.DesktopDirectory), Guid.NewGuid() + receivedPacket.Filename), receivedPacket.Content);
}
}
}
}
On the first iteration I get the first file sent, but after it I don't get anything. I've tried using a Thread.Sleep(1000) at the end of every iteration without any luck.
On the other side I have this code (for clients)
.
.
client.Connect();
foreach (var oneFilename in fileList)
client.Upload(oneFilename);
client.Disconnect();
.
.
The method Upload:
public void Upload(string filename)
{
FileInfo fileInfo = new FileInfo(filename);
Packet packet = new Packet()
{
Filename = fileInfo.Name,
Content = File.ReadAllBytes(filename)
};
byte[] serializedPacket = Tools.Serialize(packet);
netStream.Write(serializedPacket, 0, serializedPacket.Length);
netStream.Flush();
}
netStream (NetworkStream) is opened on Connect method, and closed on Disconnect.
Where's the black hole? Can I send multiple objects as I'm trying to do?
Thanks for your time.
