Here's a more concise way of doing it:

int year = 2012; // or whatever
int daysInYear = DateTime.IsLeapYear(year) ? 366 : 365;
Console.WriteLine(daysInYear); // 366
int startIndex = (7 - (int)new DateTime(year, 1, 1).DayOfWeek) % 7;
int numSundays = (daysInYear - startIndex >= 365) ? 53 : 52;
int diyExceptSunday = daysInYear - numSundays;
Console.WriteLine(diyExceptSunday); // 313

hi,

try....
private static int GetDaysInAYearWithoutSunday(int year)
{
    int days = 0;
    for (int i = 1; i <= 12; i++)
    {
        int sundaycount = GetNumberOfSundays(i, year);
        days = days += sundaycount;
    }
    return days;
}
private static int GetNumberOfSundays(Int32 Month, Int32 Year)
{
    DateTime StartDate = new DateTime(Year, Month, 1);
    Int32 iDays = DateTime.DaysInMonth(Year, Month);
    DateTime EndDate = StartDate.AddDays(iDays - 1);
    Int32 SundayCount = 0;
    while (StartDate.DayOfWeek != DayOfWeek.Sunday)
    {
        StartDate = StartDate.AddDays(1);
    }
    SundayCount = 1;
    StartDate = StartDate.AddDays(7);
    while (StartDate <= EndDate)
    {
        SundayCount += 1; StartDate = StartDate.AddDays(7);
    }
    return iDays - SundayCount;
}
static void Main(string[] args)
{
    int vvv = GetDaysInAYearWithoutSunday(2012);
}

hope this will help you.
