C # filesystemwatcher object monitors file change events, endless event triggering Solutions

Filesystemwatcher. Changed event

When the file is modified, an endless loop occurs.

The reason is:ProgramAfter receiving the notification that the file was changed, the file was modified immediately, and the file was notified of the change.

     Static   Void Watcher_changed ( Object  Sender, filesystemeventargs e ){  Lock  (OBJ) {file. appendalltext (  @"  D: \ test \ t.txt  " , "  Test  " );} Filesystemwatcher watcher = (Filesystemwatcher) sender; watcher. enableraisingevents = False  ; System. Threading. thread. Sleep (  100  ); Watcher. enableraisingevents = True  ;} 

This lineCodeIt seems that the problem has been solved: filesystemwatcher watcher = (filesystemwatcher) sender;
Watcher. enableraisingevents = false;
System. Threading. thread. Sleep (100 );
Watcher. enableraisingevents = true;
