Question

我正在尝试编写一个程序来跟踪我在游戏中死亡的次数。该程序将运行，接受用户输入并跟踪信息。当我运行该程序时，它可以工作，但是您只能输入一个键。例如，如果您启动它，然后按“ D”，它将在“死亡”变量中添加一个，但是您将无法键入其他任何内容。这是代码：

Console.WriteLine(
      "To add one to Deaths stat, press D. To add one to Charms Stat, press C. " +
      "To see all stats, press S.");

int deaths = 0;
int charms = 23;

ConsoleKeyInfo datKey;
datKey = Console.ReadKey();


if (datKey.Key == ConsoleKey.D)
{
    deaths = deaths + 1;
    Console.WriteLine();
    Console.WriteLine("Death Added");
}
if (datKey.Key == ConsoleKey.C)
{
    charms = charms + 1;
    Console.WriteLine();
    Console.WriteLine("Charm Added");
}
if (datKey.Key == ConsoleKey.S)
{
    Console.WriteLine();
    Console.WriteLine($"You have {charms} charms \nYou have died {deaths} times");

尝试一下：

using System;

namespace TestApp
{
   class Program
   {
      static void Main()
      {

         Console.WriteLine("To add one to Deaths stat, press D. To add one to Charms Stat, press C (like you'll have to use that one). To see all stats, press S.");

         int deaths = 0;
         int charms = 23;

         ConsoleKeyInfo datKey;

         do
         {
            datKey = Console.ReadKey();
            switch(datKey.Key)
            {
               case ConsoleKey.D:
                  deaths++;
                  Console.WriteLine();
                  Console.WriteLine("Death Added");
                  break;
               case ConsoleKey.C:
                  charms++;
                  Console.WriteLine();
                  Console.WriteLine("Charm Added");
                  break;
               case ConsoleKey.S:
                  Console.WriteLine();
                  Console.WriteLine($"You have {charms} charms \nYou have died {deaths} times sence starting this program");
                  break;
               default:
                  Console.WriteLine();
                  Console.WriteLine("A useless key pressed");
                  break;
            }
         } while (datKey.Key != ConsoleKey.S);

         Console.ReadKey();

      }
   }
}

如您所见，我已经将您的用户输入请求（datKey = Console.ReadKey（）;）封装在一个循环中，因此程序将继续要求用户键入键。只有用户键入S，循环才会中断。此外，我已将您的许多if语句更改为切换结构，在这种情况下最好使用

为什么此C＃代码只接受一次输入？
