Equivalent of Math.Min & Math.Max for Dates?

Question

What's the quickest and easiest way to get the Min (or Max) value between two dates? Is there an equivalent to Math.Min (& Math.Max) for dates?

I want to do something like:

 if (Math.Min(Date1, Date2) < MINIMUM_ALLOWED_DATE) {
      //not allowed to do this
 }

Obviously the above Math.Min doesn't work because they're dates.

Answer 1

There's no built in method to do that. You can use the expression:

(date1 > date2 ? date1 : date2)

to find the maximum of the two.

You can write a generic method to calculate Min or Max for any type (provided that Comparer<T>.Default is set appropriately):

public static T Max<T>(T first, T second) {
    if (Comparer<T>.Default.Compare(first, second) > 0)
        return first;
    return second;
}

You can use LINQ too:

new[]{date1, date2, date3}.Max()
