Examples

The following example shows how to use the WaitingReadCount property to generate an event log entry if the number of threads that are blocked, waiting to enter read mode, exceeds a threshold.

using (ReaderWriterLockSlim rwLock = new ReaderWriterLockSlim()) {
int waitingReadCt = rwLock.WaitingReadCount;
if (waitingReadCt > READ_THRESHOLD)
{
    performanceLog.WriteEntry(String.Format(
        "{0} blocked reader threads; exceeds recommended maximum.", 
        waitingReadCt));
}

Remarks

Use this property only for debugging, profiling, and logging purposes, and not to control the behavior of an algorithm. The results can change as soon as they have been calculated. Therefore, it is not safe to make decisions based on this property.
