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
