This works for me:

            int monthIndex;
            string desiredMonth = "May";
            string[] MonthNames=CultureInfo.CurrentCulture.DateTimeFormat.MonthNames;
            monthIndex = Array.IndexOf(MonthNames, desiredMonth) + 1;

Hope this helps.www.insteptech.com

You got the example from Deborah, use AbbreviatedMonthNames instead.  Don't try .NET programming without the MSDN library at your fingertips.

Thank you, it work only if full month name is given, for example December but not Dec.

If you know the full date then,

DateTime dt = DateTime.Parse("02-Jan-2009");

int monthNo = dt.Month;

Thank you.

To all, the anwser is :

string[] MonthNames = CultureInfo.CurrentCulture.DateTimeFormat.AbbreviatedMonthNames;

Just one simple line of code...

int month = DateTime.ParseExact("Dec", "MMM", CultureInfo.CurrentCulture).Month;
