Timer Array in c#, VS2005

[Gina_Marano]

I have created an array of timers (1-n). At first I just created
windows form timers but I read that system timers are better for
background work. The timers will just be monitoring different
directories and updating a database. No interaction with the GUI.

Problem is that the system timers do not have a tag property so I can
tie in an object.

example (old way):

public class TimerInfo
{
public string sPath;
public int iInterval;
}

private ArrayList arrTimers = new ArrayList();

private void CreateTimers(in t NUMBER_TIMERS)
{
TimerInfo Info;
System.Timers.T imer newTimer;

for (int i = 1; i <= NUMBER_TIMERS; i++)
{
Info = new TimerInfo();
Info.sPath = "c:\\";
Info.iInterval = 60000;

newTimer = new System.Timers.T imer();
newTimer.Elapse d += timerWatch_Tick ;
newTimer.Interv al = 20000;
newTimer.Tag = TimerInfo;
newTimer.Enable d = true;

arrTimers.Add(n ewTimer);
}
}

private void timerWatch_Tick (object sender, EventArgs e)
{
string sPath = ((TimerInfo)((T imer)sender).Ta g).sPath;
CheckForFile(sP ath);
}
Do I need to call Dispose if I want to reset the timer array?

foreach (System.Timers. Timer atimer in arrTimers)
{
atimer.Dispose( );
}
arrTimers.Clear ();

Thanks for your help. I am struggling as a newbie through C# even
though it is a really neat language.

Hi William:

Can you give me a short example. I am a C# and thread newbie.

But you can pass a state object to the constructor that gets passed to the
callback to get the same effect - no?

private void button24_Click( object sender, EventArgs e)
{
Console.WriteLi ne("Running a job every 5 seconds.");
string s = "MyObject";
System.Threadin g.Timer timer = null;
timer = new System.Threadin g.Timer(
delegate(object state)
{
string s1 = (string)state;
timer.Change(50 00, -1);
Console.WriteLi ne("Job ran at: {0} State:{1}",
DateTime.Now, s1);
}, s, 5000, -1);
}

As others have said, you can derive from Timer also to add your state
member(s).
