初学者的习题问题。。应该很简单。。


using System;
using System.Collections.Generic;
using System.Text;namespace ConsoleApplication7
{
    class Program
    {
        static void Main(string[] args)
        {
            const string myName = "DaQiang";
            const string daHua = "DaHua";
            const string douDou = "DouDou";
            string name;
            Console.WriteLine("please input your name!");
            name = Console.ReadLine();
            switch(name.ToLower())
            {
                case myName:
                    Console.WriteLine("it's myname!");
                break;
                case daHua:
                    Console.WriteLine("it's dahua!");
                break;
                case douDou:
                    Console.WriteLine("it's doudou!");
                break;
                default:
                Console.WriteLine("i don't know!!");
                break;
             }
             Console.ReadKey();
        }
    }
}
这段我运行调试为什么都只会显示 i don't know ! 呢！！？？ 究竟错在哪里了啊？我输入 DaQiang DaHua DouDou 都还是现实上边的提示。。
