        static void Main(string[] args)
        {
            //Get the amount of letters
            Console.WriteLine("How many letters would you like?");
            string tempAmount = Console.ReadLine();
            int letterAmount = Convert.ToInt32(tempAmount);


            //Setup
            int score = 0;
            int counter = 0;

            string tempLetter = "";

                chosenLetters.Add(tempLetter);

            while (score < letterAmount)

                {

                    currentLetter = chosenLetters[counter];
                    Console.WriteLine(currentLetter + tempLetter);
                    counter++;

                    {
                        score++;
                    }
                }

                Console.WriteLine(score);

            else
            {
                Console.WriteLine("I got all of them correct");
            }
            

            Console.ReadKey();
        }
    }
}

此外，我的代码可能非常草率和无效但我只是想让这个错误消息消失。

Answer 1

这是有问题的代码：

else
{
    Console.WriteLine("I got all of them correct");
}

如果没有前面的if语句，则不能有else子句：

if(someCondition)
{
}
else
{
}

希望这有帮助

Answer 2

问题在于else循环后错误放置的while子句。在查看您的代码后，我相信您可能在此之前无意中删除了if，或者您可以将else更改为其他内容或将其全部删除。

// Could something be missing here...
if(score != letterAmount)
{
    // Do whatever here
}
else
{
    Console.WriteLine("I got all of them correct");
}

Answer 3

我听说过if...else表达，但从来没有while...else表达。

else必须与if声明匹配。
