I have a singleton object and have a dictionary defined in it.

public class MyClass 
{
    public static readonly MyClass Instance = new MyClass();

    private MyClass
    {}

    public Dictionary<int, int> MyDictionary = new Dictionary<int, int>();
}

Now, I have two System.Timers.Timer objects updating MyDictionary.

System.Timers.Timer timer1 = new System.Timers.Timer(5);
timer1.AutoReset = false;
timer1.Elapsed += new System.Timers.ElapsedEventHandler(MyTimer1Handler);
timer1.Enabled = true;
timer1.Start();

System.Timers.Timer timer2 = new System.Timers.Timer(5);
timer2.AutoReset = false;
timer2.Elapsed += new System.Timers.ElapsedEventHandler(MyTimer2Handler);
timer2.Enabled = true;
timer2.Start();

private void MyTimer1Handler(object sender, ElapsedEventArgs e)
{
     MyClass.Instance.MyDictonary[1] = 100;
}

private void MyTimer1Handler(object sender, ElapsedEventArgs e)
{
     MyClass.Instance.MyDictonary[2] = 100;
}

My question is now, considering the elapsed event handler of timers operate uniquely on index 1 and index 2 of MyDictionary, do I need any lock on MyDictionary ?
