Semaphore object in .NET?

[tsao]

I can't find semaphore equivalent object in .NET framework
library. How can semaphore be implemented?
Thanks

.NET is not Win32 and it currently doesn't directly support the semaphore
object. You may need to implement this functionality in your own way using
System.Threading.Monitor.

Some sample code may be helpful:
class Semaphore {

public Semaphore(int maxCount, int initialCount) {

_maxCount = maxCount;

_currentCount = currentCount;

}

public void Acquire() {

lock(this) {

while (_currentCount >= _maxCount) {

Monitor.Wait(this);

}

++_currentCount;

}

}

public void Release(int count) {

lock(this) {

_currentCount -= count;

Monitor.PulseAll(this);

}

}

private int _maxCount;

private int _currentCount;

}
