Hi

Use this expression to get your output

str_weeknumber = DatetimeFormatInfo.CurrentInfo.Calendar.GetweekOfYear(Datetime.Now.AddDays(-7), DatetimeFormatInfo.CurrentInfo.CalenderWeekRule, DatetimeFormatInfo.CurrentInfo.FirstDayOfWeek).ToString

DateTimeFormatinfo is not being declared.

Also I would like the date to come as 2022/14 - yyyy/WW

strPrevWeek=Now.Year.ToString()+"/"+DateTimeFormatInfo.CurrentInfo.Calendar.GetweekOfYear(Datetime.Now.AddDays(-7), DateTimeFormatInfo.CurrentInfo.CalendarWeekRule, DateTimeFormatInfo.CurrentInfo.FirstDayOfWeek).ToString()

or

strPrevWeek=Now.Year.ToString()+"/"+System.Globalization.DatetimeFormatInfo.CurrentInfo.Calendar.GetweekOfYear(Datetime.Now.AddDays(-7),System.Globalization.DatetimeFormatInfo.CurrentInfo.CalendarWeekRule,System.Globalization.DatetimeFormatInfo.CurrentInfo.FirstDayOfWeek).ToString()

agreed @Palaniyappan due
DateTimeFormatInfo.CurrentInfo.Calendar vs. new DateTimeFormatInfo().Calendar
