Write and publish simple Windows Services on the. NET platform

Create a (VB. NET/C #) project, select Windows service application... then you can add code in the onstart class.
If you want to implement the scheduled operation and live real-time listening function, you can use the Timer class provided by. net.
The following is a code snippet.
Private void thetimer_elapsed (Object sender, system. Timers. elapsedeventargs E)
{

If (! Excondition ())

{Return;

}

Try

{

Thetimer. Enabled = false;

Mytransaction ();

}

Catch (exception es)

{

Writelog (ES. Message );

}

Thetimer. Enabled = true;

}

// Check execution Conditions

Private bool excondition ()

{

Datetime dtnow = datetime. now;

If (this. currentmode. Equals ("Auto "))

{

String [] frev = This. freqvalue. Split ('-');

Switch (this. freq)

{

Case "2": // 2-hourly

If (dtnow. Minute = 59) & (dtnow. Second <30 ))

{

Return true;

}

Break;

Case "4": // 4-daily,

If (dtnow. hour = int. parse (frev [1]) & (dtnow. minute = int. parse (frev [2]) & (dtnow. second <30 ))

{

Return true;

}

Break;

Case "8": // 8-weekly,

Int we = int. parse (frev [0]. substring (1, 1 ));

If (dtnow. dayofweek. tostring (). equals (week [we]) & (dtnow. hour = int. parse (frev [1]) & (dtnow. minute = int. parse (frev [2]) & (dtnow. second <30 ))

{

Return true;

}

Break;

Case "16": // 16-monthly,

Int Mm = int. parse (frev [0]. substring (1, frev [0]. Length-1 ));

If (dtnow. day = mm) & (dtnow. hour = int. parse (frev [1]) & (dtnow. minute = int. parse (frev [2]) & (dtnow. second <30 ))

{

Return true;

}

Break;

Default: // No trigger

Return true;

Break;
}

}

Else

{

Switch (this. startpoint)

{

Case "0 ":

Return true;

Break;

Default:

String [] ST = startpoint. Split ('-');

If (dtnow. hour = int. parse (ST [0]) & (dtnow. minute = int. parse (ST [1]) & (dtnow. second <30 ))

{

Return true;

}

Break;

}

}

Return false;

}

Register your Windows service program.

Use installutil iasserver.exe (this file is under C:/winnt/Microsoft. NET/framework/v1.1.4322 by default)

Installutil iasserver.exe

Installutil iasserver.exe/U (unmount)
