DateTime startdate = Convert.ToDateTime("01/13/2013");
DateTime enddate = Convert.ToDateTime("01/18/2013");
int count = 0;
while (startdate != enddate)
{
if (startdate.DayOfWeek.CompareTo(DayOfWeek.Sunday) != 0)
{
count++;
startdate = startdate.AddDays(1);
}
else
{
startdate = startdate.AddDays(1);
}
}
MessageBox.Show("no of days"+count);

There is a solution here: http://stackoverflow.com/questions/1617049/calculate-the-number-of-business-days-between-two-dates[^] which will need a small change to include Saturdays - it assumes a 5 day working week, where you have a six day.

But please, you don't need to convert like that!

C#

startdate =Convert.ToDateTime(DateMontYearToYearMonthDate(stdate.Text));

Don't play with text: look at using DateTime.TryParseExact[^] instead - it lets you specify exactly what the input string should look like, and convert it in a single operation (or report an error if the user entered a bad date).
