Hi there,

I have three methods these need to execute at every interval time. I
would like to know which option is better?

Option A)
Three System.Timers.Timer objects these execute each method.

timer1.Elapsed += new
System.Timers.ElapsedEventHandler(Method1_Elapsed);
timer2.Elapsed += new
System.Timers.ElapsedEventHandler(Method2_Elapsed);
timer3.Elapsed += new
System.Timers.ElapsedEventHandler(Method3_Elapsed);

Option B)
One System.Timers.Timer object that execute all methods.
timer1.Elapsed += new
System.Timers.ElapsedEventHandler(Method1_Elapsed);
timer1.Elapsed += new
System.Timers.ElapsedEventHandler(Method2_Elapsed);
timer1.Elapsed += new
System.Timers.ElapsedEventHandler(Method3_Elapsed);

Do you want the methods to execute in parallel, or in series? If you
don't mind them executing in series, I'd use the second version.
