Week Number of day like VB Function DATEPART

Question

Hi I need help. I need to get the week number of day like the VB Function: [code] DATEPART(ww Now()) [/code] I tried this but it does not calculate correctly as when the 1st is on Saterday (week1) & calculates on the 3rd Monday the below code sees it as still part of week1 & not week 2 [code] WeekOfYear = Convert.ToString(Math.Ceiling(Convert.ToDouble(ManufactureDateVar.DayOfYear) / 7)); [/code] I need to somehow replicate the VB Function in C# to the correct week number Please Assist!

Hi This is somethign written by me. DateTime c = DateTime.Now; int x = (int)Math.Ceiling(Convert.ToDouble(c.DayOfYear) / 7); if ((c.AddDays(-c.DayOfYear + 1)).DayOfWeek.GetHashCode() { return x; } else { return ( x + 1); } And this is something I found on the web. using System; using System.Globalization; public class SamplesCalendar { public static void Main() { // Gets the Calendar instance associated with a CultureInfo. CultureInfo myCI = new CultureInfo(en-US); Calendar myCal = myCI.Calendar; // Gets the DTFI properties required by GetWeekOfYear. CalendarWeekRule myCWR = myCI.DateTimeFormat.CalendarWeekRule; DayOfWeek myFirstDOW = myCI.DateTimeFormat.FirstDayOfWeek; // Displays the number of the current week relative to the beginning of the year. Console.WriteLine( The CalendarWeekRule used for the en-US culture is {0}. myCWR ); Console.WriteLine( The FirstDayOfWeek used for the en-US culture is {0}. myFirstDOW ); Console.WriteLine( Therefore the current week is Week {0} of the current year. myCal.GetWeekOfYear( DateTime.Now myCWR myFirstDOW )); // Displays the total number of weeks in the current year. DateTime LastDay = new System.DateTime( DateTime.Now.Year 12 31 ); Console.WriteLine( There are {0} weeks in the current year ({1}). myCal.GetWeekOfYear( LastDay myCWR myFirstDOW ) LastDay.Year ); } } http://msdn.microsoft.com/en-us/library/system.globalization.calendar.getweekofyear(VS.71).aspx If this answer is useful for u please mark this answer as accepted.
