How to check if one DateTime is greater than the other in C#

Question

I have two DateTime objects: StartDate and EndDate. I want to make sure StartDate is before EndDate. How is this

Answer 1

This is probably too late, but to benefit other people who might stumble upon this, I used an extension method do to this using IComparable like this:

public static class BetweenExtension
    {
        public static bool IsBetween<T>(this T value, T min, T max) where T : IComparable
        {
            return (min.CompareTo(value) <= 0) && (value.CompareTo(max) <= 0);
        }
    }

Using this extension method with IComparable makes this method more generic and makes it usable with a wide variety of data types and not just dates.

You would use it like this:

DateTime start = new DateTime(2015,1,1);
DateTime end = new DateTime(2015,12,31);
DateTime now = new DateTime(2015,8,20);

if(now.IsBetween(start, end))
{
     //Your code here
}

Answer 2

StartDate < EndDate

Answer 3

if (StartDate < EndDate)
   // code

if you just want the dates, and not the time

if (StartDate.Date < EndDate.Date)
    // code

Answer 4

if(StartDate < EndDate)
{}

DateTime supports normal comparision operators.

Answer 5

You can use the overloaded < or > operators.

For example:

DateTime d1 = new DateTime(2008, 1, 1);
DateTime d2 = new DateTime(2008, 1, 2);
if (d1 < d2) { ...

Check out DateTime.Compare method
