ManualResetEvent

[solmazg]

Hello , i am trying to make an asyncourns communicaition chat , mostly it works fine untill i come across a deadlock wich i cant explain its cuase , here are some code snippets to argue my case ,
i am new to programming and might of not understood how to use the manuaulresetevent correctly

ManualResetEvent receiveDone ;

/*(1) this is part of the code after the "client" as already connected ,it then receives its own thread to run in the thread initaits a delegate method "HandleClient" in wich it will listen for incoming messages (1)*/


new Thread(new ParameterizedThreadStart(HandleClient)).Start(Clients.ElementAt(Clients.Count - 1));
.
.

(2) /* THE BIG QUESTION is receiveDone a new instance in every thread or is it the same instance wich gets overriden when a new thread is dispatched ? */
public void HandleClient(object obj)
{
receiveDone = new ManualResetEvent(false); // manual Recent event is declered at the beging of the code , this might be the problem that receiveDone would point to a new instance every time its declerd or is it as if it as its own instance wich stays its self in every thread i dispatch...?
i need it decleard on top so i could use it in the asyncallback method ReceiveCallBack

do {
receiveDone.Reset();

currentClient.netstream.BeginRead(currentClient.ReceiveBuffer, 0, currentClient.ReceiveBuffer.Length, new AsyncCallback(ReceiveCallBack), currentClient.netstream);

receiveDone.WaitOne();
/* SOME MORE CODE */

}while(netstream.canRead()) ;

private void ReceiveCallBack(IAsyncResult ar)
{
NetworkStream ns = (NetworkStream)ar.AsyncState;

ns.EndRead(ar);

receiveDone.Set();
}

If you only want a single receiveDone event, initialize it inline or in the constructor.
