i just need some guidance on how i can display which dates in the month fall on that day. For example, if user enters 0 for monday and 31 days in that month, it will display all the momdays and which date the mondays correspond to in that month? thanks i have this so far but it doesnt seem to work for user input.

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;

namespace Calendar
{
    class Program
    {
        static int startDay = new int();
        static int totalDays = new int();

        static void Main(string[] args)
        {
            Console.Write("Enter the day the first falls on (Mon = 0, etc):    ");
            startDay = Convert.ToInt32(Console.ReadLine());
            Console.Write("How many days in the month? ");
            totalDays = Convert.ToInt32(Console.ReadLine());
        }

    public static List<DateTime> getDates()
    {
        List<DateTime> lstSundays = new List<DateTime>();
        int intMonth = DateTime.Now.Month;
        int intYear = DateTime.Now.Year;
        int intDaysThisMonth = DateTime.DaysInMonth(intYear, intMonth);
        DateTime oBeginnngOfThisMonth = new DateTime(intYear, intMonth, 1);
        for (int i = 1; i < intDaysThisMonth + 1; i++)
        {
            if (oBeginnngOfThisMonth.AddDays(i).DayOfWeek == DayOfWeek.Sunday)
            {
                lstSundays.Add(new DateTime(intYear, intMonth, i));
            }
        }
        return lstSundays;
    }
}

}

  • Welcome to Stack Overflow. Please post code *as text* rather than as images, and your requirement is too vague for us to help you at the moment. Please read https://codeblog.jonskeet.uk/2010/08/29/writing-the-perfect-question/ and bear in mind that the goal of Stack Overflow is to create a repository of high quality questions and answers. – Jon Skeet Nov 29 '16 at 17:06

    Hmmm... I don't think that creating a new profile and asking the same question again, with the exact same lack of information that was pointed out to you in the first place, is going to help. http://stackoverflow.com/questions/40869698/c-sharp-2d-arrays-calendar-month – Frauke Nov 29 '16 at 17:09
  • I was about to post the same thing. Add this to your question 'The program should ask you for the day of the week that the first day of the month falls on (numbered between 0 and 6) and how many days there are in the month. It should also ask for the name of the month.' How do you expect help? People cant read your mind – Sam Marion Nov 29 '16 at 17:11

Take a look around the site. Get your bearings. It's hard for anyone to help you without seeing your code, and a picture doesn't help. You can put it right in your question, and it appears as code when you indent it. You can also put images in your questions - the don't have to be (and shouldn't be) links to images. Make it easier for yourself to get answers by making it easier for us to give you them.
