See how to use this function in C# to discover how many more days are left in a given countdown.
DateTime startDate = DateTime.Now; DateTime endDate = DateTime.Now.AddDays(-1); TimeSpan t = startDate - endDate; double days = t.TotalDays; string result = "This is the result"; if (days < 0) { result = "phew, the date is in the past"; } else if (date = 0) { result = "We are right on the dot"; } else { result = string.format("{0} days to go!", days}; }
