Hello,

I am writing a server/client application and I have encountered a weird problem. The server handles several TCP connections and sometimes sends messages to the clients. Now, if I send these messages too "fast" they are not sent at all. However, if a Thread.Sleep(1000); command is introduced before sending a message everything works fine (except it is very slow). Maybe it is relevant that the Send() method is called by different threads , triggered by events (locking the communication object does not help). Here is the code:

public void Send(int id, string message) 
		{
			//Thread.Sleep(1000);			
			
			StreamWriter writer = new StreamWriter(connections_[id].GetStream());
			// type of connections_ is Dictionary<int, TcpClient>

			writer.WriteLine(message);
			
			writer.Flush();			   
		}

In your situation I would recommend using the Close method for the StreamWriter instead of Flush, to ensure that the data will be correctly written.
