You can use this method

C#

public List<datetime> GetDates(int year, int month)
{
   return Enumerable.Range(1, DateTime.DaysInMonth(year, month))
                      // Days: 1, 2 ... 31 etc.
                    .Select(day => new DateTime(year, month, day)) 
                     // Map each day to a date
                    .ToList(); // Load dates into a list
}

Solution 2

A simple loop it is just enough, e.g.

C#

const int MONTH = 5; // write out all the days of May 2015
DateTime dt = new DateTime(2015, MONTH, 1);
while (dt.Month == MONTH)
{
  Console.WriteLine(dt.ToString("ddd dd"));
  dt = dt.AddDays(1);
}
