Timed task-c# thread class Windows service

Principle

The most common is that the timer class in C # writes a timing method, and then hosts it to the Windows service.

Timer classification in C #

About the C # timer class in C # There are 3 of timer classes

C # Timer used by Method 1. Defined in System.Windows.Forms

C # Timer uses the Method 2. defined in the System.Threading.Timer class "

C # Timer used by Method 3. Defined in the System.Timers.Timer class

System.Windows.Forms.Timer

Applied to WinForm, it is implemented through the Windows Messaging mechanism, similar to the Timer control in VB or Delphi, implemented internally using API SetTimer. The main drawback is that the timing is imprecise and there must be a message loop that the console application (console application) cannot use.

System.Timers.Timer

Very similar to System.Threading.Timer, they are implemented through the. NET Thread pool, are lightweight, time-accurate, and have no special requirements for applications or messages.

System.Timers.Timer can also be applied to WinForm, completely replacing the timer control above. Their disadvantage is that they do not support direct drag-and-drop and require manual coding.

System.Threading.Timer

 Public classbizcommon{/// <summary>    ///Lock/// </summary>     Public Static ObjectLockObject =New Object();  Public Static voidStartTime () {//The second parameter is the parameter of the callback methodTimer T =NewTimer (Startbiz,NULL,0, the); //t.change (0, ();    }    Private Static voidStartbiz (Objecto) {if(Monitor.TryEnter (lockobject)) {FileStream fs=NewFileStream ("C:\\log.txt", FileMode.OpenOrCreate); StreamWriter SW=NewStreamWriter (FS); Sw. WriteLine ("Time :"+ DateTime.Now.ToString ("yyyy-mm-dd HH:mm:ss FFF")); Sw.        Close (); }    }}

WriteLine ("Time :"+ DateTime.Now.ToString ("yyyy-mm-dd HH:mm:ss FFF")); Sw.        Close (); }    }}

The exception that causes the task to be handled is called Missfire.//This is going to take a lot of processing, and other time periods to see if the database has been processed today. There is no processing on the re-processing and so on compensation operations.     if(Inthour = =xx&& Intminute = =xx&& Intsecond = =xx)    {        //Do something    }}
