Setting Timer Interval to Infinite

Question

I have a method that links a BO Connection.AliveInterval to a System.Timers.Timer (.NET 2).

Some connections are managed to be always connected.

Is it OK to set in such a case

if (myConnection.AliveInterval == Connection.TimeInfinite)
{
    myTimer.Interval = double.PositiveInfinity;
}

?

Should I expect that the Timer will throw exceptions or rises ever the Elapsed event ?

Answer 1

Why not myTimer.Stop()?

Answer 2

MSDN:

The value must be greater than zero, and less than or equal to Int32.MaxValue

An ArgumentException will be thrown, when the interval is greater than Int32.MaxValue, and the timer is currently enabled. If the timer is not currently enabled, no exception is thrown until it becomes enabled.

So, the PositiveInfinity will throw an exception, if the simer will be enabled.

Now, a solution would be to disable the timer and set the value to PositiveInfinity. When Enabling the Timer, catch ArgumentException and ceck the Interval to PositiveInfinity.
