This example shows how to compare dates using C#.

Usage 1:

            DateTime dateTime1 = DateTime.Parse("05/05/2009");
            DateTime dateTime2 = DateTime.Now;
            if (dateTime1.Date > dateTime2.Date)
            {
                //It's later date
            }
            else
            {
                //It's earlier or equal date
            }

Usage 2:

            int result = DateTime.Compare(dateTime1, dateTime2);
            if (result < 0)
            {
                //it is earlier
            }
            else if (result == 0)
            {
                //it is the same time as
            }
            else
            {
                //it is later
            }
