hi,

i have a problem concerning thread syncing with a manualresetevent. my code looks as below:

//this is a part of the callback of a receiving thread, qpt never gets null
//messageReceived is a manualresetevent
string qpt = myString.Substring(0, index);
Queue.Synchronized(this.Messages).Enqueue(qpt);
messageReceived.Set();

//and this is the code of my main thread, waiting for messages arriving in the queue
if (Queue.Synchronized(this.Messages).Count <= 0)
messageReceived.WaitOne(); //really waits (commented the .set)

Monitor.Enter(this.Messages);

string curLine = (string)(Queue.Synchronized(this.Messages).Dequeue());
messageReceived.Reset();

Monitor.Exit(this.Messages);

//...doing something with curline

when dequeuing, the element count is still 0. why? the queue isnt used anywhere else and it works with
while(true){
if (Queue.Synchronized(this.Messages).Count > 0)break;
}
instead of waitone (but takes 100%)
it seems that it takes a while until the queue recognises its new elements (does work with waitone if i place a debug point at waitone and always press play...). i also tried different combinations of monitor.enter, Queue.Synchronized with same results.

any ideas?
