Log out of the thread pool at a time and log out of the thread pool at a time.

Log out of the thread pool at a time and log out of the thread pool at a time.

Question: I used timer all the time and suddenly used ThreadPool to register the thread. I found that the thread won't be logged out (% >_<%), So I simply recorded a few words:

Private AutoResetEvent autoReset = new AutoResetEvent (false );
Private RegisteredWaitHandle h;

Usage:

H = ThreadPool. RegisterWaitForSingleObject (autoReset, ParallelClearLog, null, 100, false );

Set when you want to terminate (equivalent to setting a message ):

AutoReset. Set ();

 

Finally, the following operations are performed to cancel a thread:

If (h! = Null ){
H. Unregister (null );

}

Of course, since it can be canceled, it can already be reset here (this can be used for resumable upload of files, timeout and reconnection .....)

H. Unregister (autoReset );

 

(End)
