How to find weekends in "current week" in asp.net

Something like this should work for you -

DateTime GetDateFromDay(DayOfWeek dayOfWeek, int searchDirection)
{
    if (Math.Abs(searchDirection) != 1)
        throw new ArgumentException("Must be 1 or -1", "searchDirection");
    DateTime testDate = DateTime.Today;
    while (testDate.DayOfWeek != dayOfWeek)
        testDate = testDate.AddDays(searchDirection);
    return testDate;

}
