How can you implement the transfer of an array from one function to another? I’ve tried several methods already, but unfortunately they don’t want to work. I need the array elements from the Add () function to be passed to the Dump () function and display a list of these elements there. Or is this implemented with a List?

using System;
namespace organizer
{
internal class Program
{
  public static int Day {get; set; }
  public static int Quantity {get; set; }
  public static int Month {get; set; }
  private static void Add (string [] months)
  {
    Console.WriteLine ("Enter the number of the month in which you want to add the case");
    int counter = 1;
    foreach (string mont in months)
    {
      Console.WriteLine (months [counter ++] + $ "- {counter - 1}");
      if (counter & gt; 12)
      {
        break;
      }
    }
    Console.WriteLine (new string ('-', 25));
    Console.Write ("Month number:");
    Month = Convert.ToInt32 (Console.ReadLine ());
    Console.Write ("Enter the day of the month on which you want to add the case:");
    Day = Convert.ToInt32 (Console.ReadLine ());
    if (Month == 2)
    {
      while (Day & gt; 28)
      {
        Console.WriteLine ("There are 28 days in February.");
        Console.Write ("Please re-enter the value:");
        Day = Convert.ToInt32 (Console.ReadLine ());
        if (Day & lt; 28 || Day & lt; = 0)
        {
          break;
        }
      }
    }
    Console.WriteLine (new string ('-', 25));
    Console.Write ("Enter the number of cases you want to add:");
    Quantity = Convert.ToInt32 (Console.ReadLine ());
    Console.WriteLine ($ "What activities do you want to add in {months [Month]} for the day {Day}?");
    Console.WriteLine (new string ('-', 25));
    Console.WriteLine ($ "The number of cases to add: {Quantity}");
    string [] affairs = new string [Quantity];
    for (int i = 0; i & lt; affairs.Length; i ++)
    {
      affairs [i] = Console.ReadLine ();
      Console.WriteLine ($ "Left to add cases: { --Quantity}");
    }
  }
  private static void Dump (string month, int day)
  {
    Console.WriteLine ($ "To-do list for {month [Month]} on day {day}");
    // foreach (var aff in affairs)
    // {
    // Console.Write (aff);
    //}
  }
  private static void Main (string [] args)
  {
    string [] months = new string [13];
    #region Months
    months [0] = "Months:";
    months [1] = "January";
    months [2] = "February";
    months [3] = "March";
    months [4] = "April";
    months [5] = "May";
    months [6] = "June";
    months [7] = "July";
    months [8] = "August";
    months [9] = "September";
    months [10] = "October";
    months [11] = "November";
    months [12] = "December";
    #endregion
    Console.WriteLine ("LKL");
    Console.WriteLine ("Select the number of the operation you want to perform:" +
      "\ n1 - Add to-do list" +
      "\ n2 - Display the to-do list" +
      "\ n3 - Move things over to the next month");
    int choice;
    while (true)
    {
      choice = Convert.ToInt32 (Console.ReadLine ());
      if (choice == 1)
      {
        Add (months);
      }
      else if (choice == 2)
      {
        Dump (months [Month], Day);
      }
      else if (choice == 3)
      {
      }
      else
      {
      }
    }
  }
}

}

Answer 1

This is how you have everything static, so they will refer to all elements of the class through
. Example: Program.

private static void Dump ()
      {
        foreach (var month in Program.Add)
        {
          Console.WriteLine ($ "To-do list for {month [month]} on day {Program.Day}"); 
}
       }

Answer 2

Get the dictionary inside the class in which you will store everything, and transmit it to DUMP. Only Static Remove.
