VB.NET Core Classes in a Nutshell

Name

ThreadPool

Synopsis

Creating or destroying a thread takes a fair amount of work. Therefore, if you pool threads, your program executes more efficiently since you get rid of the overhead associated with creating and destroying threads. There is one thread pool per process. To queue work to execute by this pool of worker threads, call any of the ThreadPool shared methods. QueueUserWorkItem() queues a delegate to execute when one of the pool’s threads becomes free. RegisterWaitForSingleObject() takes a WaitHandle and executes the specified method either when the WaitHandle is in the signaled state or when a time-out occurs. BindHandle() and UnsafeQueueUserWorkItem() are provided for compatibility with the Win32 API.
