TimeSpan Time Calculation, Minutes - ho to convert time span to int

I have the folowing code,

now the question is what is the best way to preform this:

also take in notice the "minAdd" can pass 60, meaning 90min add (an hour an half etc)

thanks,

        int minAdd = Convert.ToInt16(txtMinAdd.text);
        DateTime now = DateTime.Now;
        DateTime nextEvent = DateTime.Now.AddMinutes(minAdd);
        TimeSpan diff = now - nextEvent;
        if (diff > minAdd) -------------- PROBLEM HERE
        {
            //act here
        }

EDIT: As noted by Reed, the code you've shown is pretty pointless. I assume you actually want to get nextEvent from somewhere else.

I suspect you just want:

if (diff.TotalMinutes > minAdd)
{
}

Or you could use:

TimeSpan minTimeSpan = TimeSpan.FromMinutes(Convert.ToInt16(txtMinAdd.text));
...
if (diff > minTimeSpan)
{
}

Since diff is based on nextEvent, which is based exactly on minAdd, there is no reason for this check - it will never be true.

Also, in your code, diff will always be negative if minAdd is positive, as you're subtracting a future event (nextEvent) from DateTime.Now.

If you are trying to schedule an event to occur at a point in time, you may want to consider using a Timer, and scheduling the timer to occur at some point in time based on the event time:

DateTime nextEvent = DateTime.Now.AddMinutes(minAdd);
TimeSpan diff = nextEvent - DateTime.Now;

// Schedule a timer to occur here
someTimer.Interval = diff.TotalMilliseconds; // Timer intervals are typically in ms
