See in a method which is working with thread if we have a loop we must use some code to stop the loop. for example i wrote the following code which passes to ThreadStart: for(;;) { bytesRcvd = client.Receive(rcvBuffer, 0, rcvBuffer.Length, SocketFlags.None); msg1 = Encoding.UTF8.GetString(rcvBuffer); msg3 = "\0"; msg1 = msg1.Trim(msg3.ToCharArray()); Array.Clear(rcvBuffer, 0, rcvBuffer.Length); } the thread is await until the data received if we wrote a code in loop that has no stopping, CPU will be busy by 100%.

I've designed a udp connection using socket and threading. I want to know how I can change sound to an array of byte and change an array of byte to sound. So how can I set received sound to speaker and give output sound from its device like microphone? What should I do? Thanks a lot for your answers. Bahman
