When you use C # To write Windows Services, many examples on the Internet say that you can use the timer in the Toolkit, but in fact this timer does not work, for specific reasons, microsoft claimed to be a framework bug.

Both timer in Windows form and timer in components are inherited from system. windows. form. timer, not the system we need. timers, inherited from system. timers can only be created manually.

Public windowsservicedemo ()

Initializecomponent ();

System. Timers. Timer T = new system. Timers. Timer (1000); // instantiate the Timer class and set the interval to 10000 milliseconds;

T. elapsed + = new system. Timers. elapsedeventhandler (timeelapse); // execute the event at the time of arrival;

T. autoreset = true; // set whether to execute once (false) or always execute (true );

T. Enabled = true; // whether to execute the system. Timers. Timer. elapsed event;

}

Public void timeelapse (Object source, system. Timers. elapsedeventargs E)

{

// EventLog log = new EventLog ();

// Log. Source = "My applications ";

// Log. writeentry ("one second call", eventlogentrytype. information );

Filestream FS = new filestream (@ "D: \ timetick.txt", filemode. openorcreate, fileaccess. Write );

Streamwriter m_streamwriter = new streamwriter (FS );

M_streamwriter.basestream.seek (0, seekorigin. End );

M_streamwriter.writeline ("after one second" + datetime. Now. tostring () + "\ n ");

M_streamwriter.flush ();

M_streamwriter.close ();

FS. Close ();
