The total number of threads that are waiting to enter read mode.
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()) {
Using rwLock As New ReaderWriterLockSlim()
int waitingReadCt = rwLock.WaitingReadCount;
if (waitingReadCt > READ_THRESHOLD)
{
performanceLog.WriteEntry(String.Format(
"{0} blocked reader threads; exceeds recommended maximum.",
waitingReadCt));
}
Dim waitingReadCt As Integer = rwLock.WaitingReadCount
If waitingReadCt > READ_THRESHOLD Then
performanceLog.WriteEntry(String.Format( _
"{0} blocked reader threads; exceeds recommended maximum.", _
waitingReadCt))
End If
