The 'dd' format will print the day numbers. 

using System;

namespace forgetCode
{
    class Program
    {
        static void Main(string[] args)
        {
            DateTime now = DateTime.Today;
            for (int i = 0; i < 7; i++)
            {
                Console.WriteLine(now.ToString("dd"));
                now = now.AddDays(1);
            }          
        }

    }
}
