Wait(TimeSpan) is a synchronization method that causes the calling thread to wait for the current task instance to complete until one of the following occurs:

  • The task completes successfully.

  • The task itself is canceled or throws an exception. In this case, you handle an AggregateException exception. The AggregateException.InnerExceptions property contains details about the exception or exceptions.

  • The interval defined by timeout elapses. In this case, the current thread resumes execution and the method returns false.
