threads, timers, passing arguments, time-slicing, C#

i'm trying to demonstrate timeslicing among equal high priority threads without putting threads to sleep. to do this i'm trying to run a timer while executing a very long loop sequence in order to get the processor to round-robin through the high priority threads. here's what i have:

static void Main(string[] args)
{
System.Timers.T imer aTimer = new System.Timers.T imer();

// Hook up the Elapsed event for the timer.
aTimer.Elapsed += new ElapsedEventHan dler(OnTimedEve nt)

// Set the Interval to 5 seconds (5000 milliseconds).
aTimer.Interval = 5000;
aTimer.Enabled = true;


Console.WriteLi ne( "\n \nThis demonstrates time-slicing among high priority threads.\nThe processor alternates between the two high priority threads first before letting the low priority thread run.\n \n");
//class time slice object
imeSlice sliceTS = new TimeSlice();
//high priority thread #1
Thread threadHighSlice 1 = new Thread(new ThreadStart(sli ceTS.Print));
threadHighSlice 1.Priority = ThreadPriority. Highest;
threadHighSlice 1.Name = "1";
threadHighSlice 1.Start();
//high priority thread #2
Thread threadHighSlice 2 = new Thread(new ThreadStart(sli ceTS.Print));
threadHighSlice 2.Priority = ThreadPriority. Highest;
threadHighSlice 2.Name = "2";
threadHighSlice 2.Start();
//high priority thread #2
Thread threadHighSlice 3 = new Thread(new ThreadStart(sli ceTS.Print));
threadHighSlice 3.Priority = ThreadPriority. Highest;
threadHighSlice 3.Name = "3";
threadHighSlice 3.Start();
//low priority thread
Thread threadLowSlice = new Thread(new ThreadStart(sli ceTS.Print));
threadLowSlice. Priority = ThreadPriority. Lowest;
threadLowSlice. Name = "Low";
threadLowSlice. Start();

// Keep the timer alive until the end of Main.
GC.KeepAlive(aT imer);

}


// Specify what you want to happen when the Elapsed event is
// raised.
private static void OnTimedEvent(ob ject aTimer, ElapsedEventArg s e)
{
Thread current = Thread.CurrentT hread;
MessageBox.Show (current.Name);
}


}

class TimeSlice : EventArgs
{

public void Print()
{
Thread current = Thread.CurrentT hread;
int number = 0;
int num = 0;
while(num < 100000)
{
Console.Write(c urrent.Name);
num = num + 1;

}
}

i'm trying to get the timer elapsed event to print the thread currently being executed in a message box. but i can't seem to figure out how to pass the value. is there an easier way to accomplish what i'm trying to do?
