Question

Well as the title says how can i detect a disconnect with ‘ReceiveAsync’ with all other .net network patterns you could just look if you recived 0 bytes or if any exception was throw however this does not seem to be true any more with this pattern…

My first recive return 0 bytes but the second works thats why im confused….

It’s just the same:

        void OnReceiveComplete(IAsyncResult iar)         {             try             {                 int count = sock.EndReceive(iar);                 if (count == 0)                 {                     Console.WriteLine('{0} closed by remote host', ID);                     sock.Close();                 }                 else                 {                     int total = Interlocked.Increment(ref totalBytes);                     Console.WriteLine('{0} received {1} (total: {2})',                         ID, buff[0], total);                     StartReceive();                 }             }             catch (Exception x)             {                 Console.WriteLine('{0} error from EndReceive: {1}', ID, x);             }         }
