Concept Switching Menus

To switch menus, do the following

1. Inject an IConsoleMenuController into the constructor of your class.
2. In the WorkAsync method, call one of the three overloads of the IConsoleMenuController.DisplayMenuAsync method.

Example:

using System.Threading.Tasks;
using ConsoleMenuHelper;

namespace Example1
{
    [ConsoleMenuItem("Hello1")]
    public class LaunchSubMenuItem : IConsoleMenuItem
    {
        private readonly IConsoleMenuController _menuController;

        public LaunchSubMenuItem(IConsoleMenuController menuController)
        {
            _menuController = menuController;
        }

        public async Task<ConsoleMenuItemResponse> WorkAsync()
        {
            await _menuController.DisplayMenuAsync("Hello2", "Hello Two", BreadCrumbType.Concatenate);
            return await Task.FromResult(new ConsoleMenuItemResponse(false, true));
        }

        public string ItemText => "Show Hello 2 menu!";

        
        /// <summary>Optional data from the attribute.</summary>
        public string AttributeData { get; set; }
    }
}

Notes

• Here I'm using the overload with the most parameters.
  • I specify the name of the menu, "Hello2", which should be the title of the menu in the ConsoleMenuItemAttribute that decorates all your menu item classes.
  • I specify a title, "Hello Two", for the menu. This will appear at the top of the menu above the options.
  • I specify a breadcrumb trail type, BreadCrumbType.Concatenate. There are three different values available:
    1. BreadCrumbType.None - Don't show a breadcrumb trail
    2. BreadCrumbType.ParentOnly - Show the parent and child only
    3. BreadCrumbType.Concatenate - Look at the parents breadcrumb trail and add to it. If the parent doesn't have a breadcrumb trail then just use the parent's title to build one.
