C# Get Week Number In Month

Problem : How do I get number of week per month for the particular date?

Solution :

// Get Num of Week Per Month
public static int GetWeekInMonth(DateTime date)
{
    DateTime tempdate = date.AddDays(-date.Day + 1);
    CultureInfo ciCurr = CultureInfo.CurrentCulture;
    int weekNumStart = ciCurr.Calendar.GetWeekOfYear(tempdate, CalendarWeekRule.FirstFourDayWeek, ciCurr.DateTimeFormat.FirstDayOfWeek);
    int weekNum = ciCurr.Calendar.GetWeekOfYear(date, CalendarWeekRule.FirstFourDayWeek, ciCurr.DateTimeFormat.FirstDayOfWeek);
    return weekNum - weekNumStart + 1;
}
