Answer 1

You can use this if you want the first Saturday in your range.

var saturday = range.FirstOrDefault(dt => dt.DayOfWeek == DayOfWeek.Saturday);

Or this if you want all saturdays in your range:

var saturday = range.Where(dt => dt.DayOfWeek == DayOfWeek.Saturday);

Answer 2

Use the DayOfWeek property on the DateTime Object.

        var dayList = new List<DateTime>();

        foreach(var day in dayList)
        {
            if (day.DayOfWeek == DayOfWeek.Sunday) //Sunday
            if (day.DayOfWeek == DayOfWeek.Monday) //Monday
            etc...
        }

Or Linq

        dayList.Where(x => x.DayOfWeek == DayOfWeek.Sunday).ToList();

how to get "Saturday" from List range

Based on your comment;

DateTime saturday = range.Where(d => d.DayOfWeek == DayOfWeek.Saturday).FirstOrDefault();

I assumed your range has only one Saturday, this will return it.
