所以正如标题所说，我的代码不会编译我现在和之前遇到多个问题，当它的格式不同时，它在某种程度上起作用。但现在代码完全拒绝运行，以我目前的理解水平，我无法找出问题，但我相信问题只是我格式化程序的方式，因此它遵循流程图。

两个问题：

  1. 在外部 do while 循环中的最后一个 while 之前，您缺少一个松散的括号。
  2. 您需要在声明“playAgain”字符时对其进行初始化。

您的程序中有两个错误。首先，在使用变量之前，必须始终对其进行初始化。如果您查看playAgain变量可以采用的不同路径，则该值仅在您的if (guessCount++ == maxGuesses)路径中设置。如果条件为假，您将获得while没有任何价值的零件。您可以将声明更改为

char playAgain = 'n';

第二个错误是缺少括号。如果你仔细做缩进，你会看到：

do
{
    //Bunch of code
    if (guessCount++ == maxGuesses)
    {
        //INCRIMENT GAME COUNT
        gameCount++;
        Console.WriteLine("You lost");
        //DISPLAY CORRECT NUMBER IF TOO MANY INCORRECT GUESSES
        Console.WriteLine("\nThe number was {0},better luck next time!", randomNumber);
        guessCount = 1;

        //PROMPT TO PLAY AGAIN

        Console.WriteLine("Would you like to play again? (Y/N)");
        playAgain = char.Parse(Console.ReadLine());

} while (playAgain == 'y' || playAgain == 'Y');

如您所见，您缺少if括号，应该是

   playAgain = char.Parse(Console.ReadLine());
   }

} while (playAgain == 'y' || playAgain == 'Y');

此外，还有很多可以改进的地方。例如，您应该将变量声明放置在使用它们的地方，而不是放在类的顶部。每个评论都应该是一个单独的方法；如果您的 Main 而不是一大堆代码，那么您遵循流程图会更容易：

private static void Main(string[] args)
{
    WelcomeTheUser();
    InitializeWinCountAndGameCount();
    Play();
    DisplayWinCount();
}

如果你保持你的函数很小，你也可以避免大量放错位置的括号。
