Remarks
Causes the current thread to wait until the latch has counted down to zero, an exception is thrown, or the specified waiting time elapses.

If the current count is zero then this method returns immediately with the value

Copy
true
.

If the current count is greater than zero then the current thread becomes disabled for thread scheduling purposes and lies dormant until one of five things happen:

  • The count reaches zero due to invocations of the CountDown() method;
  • This ICountDownLatch instance is destroyed;
  • The countdown owner becomes disconnected;
  • Some other thread the current thread; or
  • The specified waiting time elapses.

If the count reaches zero then the method returns with the value

Copy
true
.

If the current thread:

  • has its interrupted status set on entry to this method; or
  • is while waiting,
then System.Exception is thrown and the current thread's interrupted status is cleared.

If the specified waiting time elapses then the value

Copy
false
is returned. If the time is less than or equal to zero, the method will not wait at all.
