(30) C # Timer Class

There are three kinds of timer

1, System.Windows.Forms.Timer

The main disadvantage of this application in WinForm is that the timing is imprecise and must have a message loop that the console application (console application) cannot use

Drag the Timer control to the form

Right-click to set timer properties

There are two common properties

Enabled is set to True (False by default) and can be executed automatically after running

Interval set how often the time interval runs in milliseconds, 1000 milliseconds equals 1 seconds

Double-click the Timer1 control to start writing code

Private void Timer1_Tick (object  sender, EventArgs e)        {            MessageBox.Show ("  Hello");        }

Run the program so that it will pop up with a hello box every second and keep running .....

2, System.Timers.Timer
