This is Thread-Safe right?

Question

Just checking... _count is being accessed safely, right?

Both methods are accessed by multiple threads.

private int _count;

public void         


        

Answer 1

you can do the following if you don't want to lock or move to a semaphore:

if (_count >= MAXIMUM) return; // not necessary but handy as early return
if(Interlocked.Increment(ref _count)>=MAXIMUM+1)
{
    Interlocked.Decrement(ref _count);//restore old value
    return;
}
Task.Run(() => Work());

Increment returns the incremented value on which you can double check whether _count was less than maximum, if the test fails then I restore the old value
