Question

What is the best way to reset a semaphore that have threads waiting on it. Right now all I can think of is just doing a while loop and releasing the semaphore until a semaphore full exception occurs. I’m not sure what is the best practice.

semaphore.Close();
semaphore = new Semaphore(0,1);

Or

while(true)
{
   try
   {
      semaphore.Release();
   }
   catch
   {
      break;
   }
}
semaphore = new Semaphore(0,1);

Answer 1

If you want to do that, are you sure you want a Semaphore to start with? Perhaps a ManualResetEvent would be more appropriate?
