控制台应用程序中的简单菜单

我正在尝试重复我的菜单,所以在选择并执行选项1后,它将返回菜单并要求选择其他选项

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();
    }
}

以下是取出内容的方法:

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() + " ");
    }

我知道我的措辞很差,所以我希望有人理解我的要求:P

您可以使用do while循环 对你的DispalyMenu()方法做一点修改,然后像这样返回结果

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);
}

并将其写入Main()方法

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

因此,暂时用户不输入'5',代码将在循环中执行。 希望有所帮助。

请参阅:http://msdn.microsoft.com/en-us/library/471w8d85(v=vs.110).aspx

将主要功能替换为:

static void Main(string[] args) {
    FootballTeams MyCode = new FootballTeams();

    MyCode.ListInit();

    ConsoleKeyInfo cki;

    do {
        MyCode.DisplayMenu();
        cki = Console.ReadKey(false); // show the key as you read it
        switch (cki.KeyChar.ToString()) {
            case "1":
                MyCode.AddTeams();
                break;
            case "2":
                MyCode.DisplayTeams();
                break;
            // etc..
        }
    } while (cki.Key != ConsoleKey.Escape);

}

基本上,你需要循环直到他们按Esc键。每次阅读密钥时,您都可以执行所选的操作。

现在有一个nuget包

https://github.com/splttingatms/EasyConsole

实施例

添加nuget包之后,菜单可以通过以下方式实现,这是一个非常基本的选项

static void Main(string[] args)
{
    var menu = new EasyConsole.Menu()
      .Add("foo", () => Console.WriteLine("foo selected"))
      .Add("bar", () => Console.WriteLine("bar selected"));
    menu.Display();
}

在操作中,您可以放置​​任何方法以在选中时运行

这将输出类似这样的内容

  1. FOO
  2. 选择一个选项:
