An existing connection was forcibly closed by the remote host

[imoon]

Hello EveryOne!

I am working on TCP socket programmming Client/Server. I am using asynchronous methods.What it does - I have a server Application which can accept more then 5 client at the same time. After stablishing the connection to the server I start reveving data from client using Begin Recive, when i forcefully disconnect one of my client i get a error "An existing connection was forcibly closed by the remote host ". I want to know is their any method to solve this issue.

void ReceiveData(IAsyncResult iar)
{
   try
   {
      Socket client = (Socket)iar.AsyncState;
      int recv = client.EndReceive(iar);
      if (recv == 0)
      {
         conStatus.Text = "Client" + client.RemoteEndPoint.ToString() + " has disconnected.";
         server.BeginAccept(new AsyncCallback(AcceptConn), server);
         return;
   }
   string receivedData = Encoding.ASCII.GetString(data, 0, recv);
   results.Items.Add(receivedData + client.RemoteEndPoint);
}

You could finish your try/catch block by having a catch for it then ignoring it?
The error comes when you try to do a read/write operation on a socket that has been closed.

Well try/catch would be a pretty proper solution in this case....

But you could always Poll() for connectivity and see when it disconnects.
