How to get the name of each day in next month?

Question

DateTime dt = new DateTime();
dt = DateTime.Now.AddMonths(1);
int x = DateTime.DaysInMonth(dt.Year, dt.Month);
MessageBox.Show(x.ToString());  // works ok - 31

You can also leverage Enumerable.Range and LINQ (and the DaysOfWeek enum)

DateTime dt = DateTime.Now.AddMonths(1);

Enumerable.Range(1, DateTime.DaysInMonth(dt.Year, dt.Month))
    .Select(dayNumber => new DateTime(dt.Year, dt.Month, dayNumber))
    .Select(dayName => dayName.DayOfWeek.ToString()).ToList()
    .ForEach(day => MessageBox.Show(day));

The two .Select()s can be merged but I kept them separated for readability.
