C # Calculates the number of days difference between two dates

Note: For example, between 1900-01-01 and 1900-01-01, one day

private static int DateDiff (DateTime datestart, datetime dateend)        {            datetime start = Convert.todatetime ( Datestart.toshortdatestring ());            DateTime end = Convert.todatetime (datestart.toshortdatestring ());            TimeSpan SP = end. Subtract (start);            Return sp. Days;        }
