Various note formats provided by. NET

. NET provides three note types:
1, System. Timers. Timer:
This Timer uses threads in the thread pool to execute tasks. Since it uses threads in the thread pool, it must synchronize threads when accessing resources used by tasks !, You can specify a thread to execute a task,

2, System. Threading. Timer:
Similar to Timer in thread 1, a thread in the thread pool is used to execute tasks, but a specified Thread cannot be used to execute tasks.


3, System. Windows. Forms. Timer:
This Timer is characteristic that the thread used to execute the task is dedicated to the job-related window. You must never use this Timer to execute tasks that take too long (for example, a few minutes). Otherwise, the interface will not respond.
