How to compare date in ASP.net?

Hello @ fnaf, in ASP.NET/C#, the best way to compare dates is to use DateTime rather than comparing date strings.

Compare two dates

DateTime date1 = DateTime.Parse("2026-08-10");
DateTime date2 = DateTime.Parse("2026-08-11");

if (date1 < date2)
{
    // date1 is earlier
}
else if (date1 > date2)
{
    // date1 is later
}
else
{
    // dates are equal
}

Compare only the date, ignoring time

If the DateTime values contain different times:

if (date1.Date == date2.Date)
{
    // Same date
}

Or:

if (date1.Date < date2.Date)
{
    // date1 is before date2
}

Check if a date is between two dates

if (date >= startDate && date <= endDate)
{
    // Date is within the range
}

Tip: If the date comes from a textbox or user input, prefer DateTime.TryParse() instead of DateTime.Parse() to avoid exceptions from invalid input.
