Gets the total number of threads that are waiting to enter the lock in write mode.
public:
property int WaitingWriteCount { int get(); };public int WaitingWriteCount { get; }member this.WaitingWriteCount : intPublic ReadOnly Property WaitingWriteCount As IntegerThe total number of threads that are waiting to enter write mode.
The following example shows how to use the WaitingWriteCount property to generate an event log entry if the number of threads that are blocked, waiting to enter write mode, exceeds a threshold.
using (ReaderWriterLockSlim rwLock = new ReaderWriterLockSlim()) {
Using rwLock As New ReaderWriterLockSlim()
int waitingWriteCt = rwLock.WaitingWriteCount;
if (waitingWriteCt > WRITE_THRESHOLD)
{
performanceLog.WriteEntry(String.Format(
"{0} blocked writer threads; exceeds recommended maximum.",
waitingWriteCt));
}
Dim waitingWriteCt As Integer = rwLock.WaitingWriteCount
If waitingWriteCt > WRITE_THRESHOLD Then
performanceLog.WriteEntry(String.Format( _
"{0} blocked writer threads; exceeds recommended maximum.", _
waitingWriteCt))
End If
