c# - A simple menu in a Console Application

Question

I am trying to get my menu to repeat, so after selecting and doing option 1, it will got back to the menu and ask for another option to be chosen

class Program
{
    static void Main(string[] args)
    {

        FootballTeams MyCode = new FootballTeams();

        MyCode.ListInit();
        MyCode.DisplayMenu();
        MyCode.AddTeams();
        Console.ReadLine();

        MyCode.ListInit();
        MyCode.DisplayMenu();
        MyCode.DisplayTeams();
        Console.ReadLine();

        MyCode.ListInit();
        MyCode.DisplayMenu();
        MyCode.Delete();
        Console.ReadLine();

        MyCode.ListInit();
        MyCode.DisplayMenu();
        MyCode.TeamSearch();
        Console.ReadLine();
    }
}

Here are the methods with the contents taken out:

class FootballTeams
{


    public FootballTeams(){ }

    List<string> teams;
    public void ListInit()


    public void DisplayMenu()
   {   
    Console.WriteLine("Football Manager");
    Console.WriteLine();
    Console.WriteLine("1. Add a Football team");
    Console.WriteLine("2. List the Football teams");
    Console.WriteLine("3. Search for a Football team");
    Console.WriteLine("4. Delete a team");
    Console.ReadLine();
    }



    public void AddTeams()
    {
      Console.WriteLine("Enter a team to be added: ");
      string userinput = Console.ReadLine();
      if (teams.Count < 10)
      {
       if (userinput != "Colchester")
        {
          teams.Add(userinput);
          foreach (var item in teams)
          Console.Write(item.ToString() + " ");
         }
        else
          Console.Write("NOT ALLOWED");
         }
       else
         Console.Write("MAXIMUM LIMIT REACHED");
      }


    public void DisplayTeams()
    {
     foreach(var item in teams)
     Console.Write(item.ToString() + " ");
    }

    public void TeamSearch()
    {
     Console.WriteLine("Please enter the team you wish to search for: ");
     string userinput = Console.ReadLine();
     if (teams.Contains(userinput))
     Console.WriteLine("Success, team " + userinput);
    }

    public void Delete()
    {
      Console.WriteLine("Enter a team you wish to delete: ");
      string userinput = Console.ReadLine();
      teams.Remove(userinput);
      foreach (var item in teams)
      Console.Write(item.ToString() + " ");
    }

I know I have worded this poorly, so I hope that someone understands what I'm asking :P

Answer 1

You can use a do while loop for the purpose Make a little modification to your DispalyMenu() method and return the result like this

static public int DisplayMenu()
{   
  Console.WriteLine("Football Manager");
  Console.WriteLine();
  Console.WriteLine("1. Add a Football team");
  Console.WriteLine("2. List the Football teams");
  Console.WriteLine("3. Search for a Football team");
  Console.WriteLine("4. Delete a team");
  Console.WriteLine("5. Exit");
  var result = Console.ReadLine();
  return Convert.ToInt32(result);
}

and write this in your Main() method

int userInput = 0;
do
{
  userInput = DisplayMenu();
}while(userInput!=5);

So for the time being the user does not enter '5', the code will execute in the loop. Hope that helps.
