How to call items at specific time in timers

I have to start timer at 12AM daily. It has to execute 4 items i have with 15min interval

i.e, item1 should be executed @12, item2 @12 15 and so on

i have written below code:

To start timer @12Am :-

private void SetTimerValue()

{

//// trigger the event at 12 AM.

DateTime requiredTime = DateTime.Today.AddHours(0).AddMinutes(00);

if (DateTime.Now > requiredTime)

{

requiredTime = requiredTime.AddDays(1);

}

TimeSpan periodTS = requiredTime - DateTime.Now;

myTimer = new System.Threading.Timer(new TimerCallback(TimerAction), null, 0, (long)periodTS.TotalMilliseconds);

}

In TimerAction i have 4 items which has to be called @ 15min interval

public void TimerAction(object e)

{

var collection = new List { "item1", "item2", "item3", "item4" };

// When timer is 12am, execute item1

// When timer is 12 15am, execute item2

// When timer is 12 30am, execute item3

// When timer is 12 45am, execute item4

}

My question is :

1. Can i create seperate timer inside TimerAction method?

2. How should i loop and execute all these 4 items?

3. Is there any better approach?. Please guide me to do this.

i hope this code can help you ..

public class TimerApp

{

private int invokeCount;

private int maxCount;

public List collection = new List { "item1", "item2", "item3", "item4" };

public TimerApp(int count)

{

invokeCount = 0;

maxCount = count;

}

// This method is called by the timer delegate.

public void CheckStatus(Object stateInfo)

{

AutoResetEvent autoEvent = (AutoResetEvent)stateInfo;

Console.WriteLine("{0} Checking status {1,2}.", DateTime.Now.ToString("h:mm:ss.fff"), collection[invokeCount].ToString());

++invokeCount;

if (invokeCount == maxCount)

{

// Reset the counter and signal Main.

invokeCount = 0;

autoEvent.Set();

}

class Program

{

static void Main(string[] args)

{

// Create an event to signal the timeout count threshold in the

// timer callback.

AutoResetEvent autoevent = new AutoResetEvent(false);

TimerApp timerapp = new TimerApp(4);

// Create an inferred delegate that invokes methods for the timer.

TimerCallback timercallback = timerapp.CheckStatus;

// Create a timer that signals the delegate to invoke

// CheckStatus after two second, and every 1 second

// thereafter.

Console.WriteLine("{0} Creating timer.\n", DateTime.Now.ToString("h:mm:ss.fff"));

Timer stateTimer = new Timer(timercallback, autoevent, 2000, 1000);

// When autoEvent signals the second time, dispose of

// the timer.

autoevent.WaitOne(10000, false);

stateTimer.Dispose();

Console.WriteLine("\nDestroying timer.");

Console.ReadKey();

}
