C # multithreading (4) -- Use of Timer

1. the role of the Timer class is to set a timer to regularly execute the user-specified function, and the transfer of this function depends on another Proxy object timercallback, which must be specified when the timer object is created, and cannot be changed. After the timer starts, the system automatically creates a new thread and executes the user-specified function in this thread.

2. timer timer = new timer (timerdelegate, S, 1000,100 0); the first parameter specifies the timercallback proxy object; the second parameter indicates the same as the waitcallback proxy object mentioned above, as a data transmission object, it is passed to the method to be called. The third parameter is the delay time-the time from the start of the timer, in milliseconds; the fourth parameter is the timer interval. After the timer starts, the method represented by timercallback will be called every so long time, in milliseconds. This statement sets the timer delay time and interval to one second.

3. the timer settings can be changed as long as timer is called. the change () method is a parameter type overload method. The general prototype is as follows: public bool change (Long, long );
