Question

我正在尝试创建一个程序，其中CommonCharacters Student和HonorsStudent（子类到CommonCharacter）＆＃34;战斗＆＃34;通过试图让对方获得较低的测试分数。在我的主班（见下文）中，我试图模拟这个＆＃34;战斗＆＃34;在角色之间，但我无法让角色继续＆＃34;战斗＆＃34;直到除了一个以外的所有人我在while语句的条件中使用了Count属性，以便循环直到计数达到1.因为循环在3次运行后结束，所以我从来没有机会从中移除对象。（当他们的afterScore <= 50时，荣誉学生将被删除，当他们的afterScore <= 25时，学生将被删除）。

我的while循环有问题吗？

class Program
{
    static void Main(string[] args)
    {
        List<CommonCharacter> characters = new List<CommonCharacter>();
        characters.Add(new Student("Sarah", "female", 1));
        characters.Add(new Student("Kevin", "male", 2));
        characters.Add(new HonorsStudent("Matthew", "male", 3));
        characters.Add(new HonorsStudent("Gwen", "female", 4));

        // This will be used to choose a character to "battle" at random from the List of characters
        Random random = new Random();

        while(characters.Count > 1)
        {
            foreach(CommonCharacter CommonCharacter in characters)
            {
                int randomStudent = random.Next(characters.Count);

                // This makes sure there is no instance where a student "attacks" themself
                if (CommonCharacter.Name == characters[randomStudent].Name)
                {
                    random.Next(characters.Count);
                }
                else
                {
                    int points = CommonCharacter.TakeTest();

                    if (points > 0)
                    {
                        int afterScore = 100 - points;
                        Console.WriteLine(CommonCharacter.Name + " reports " + characters[randomStudent].Name + " for cheating and loses them " + points + " points.");
                        Console.WriteLine(characters[randomStudent].Name + " now has a test score of " + afterScore);
                        Console.WriteLine();
                    }
                    else if (points == 0)
                    {
                        Console.WriteLine(CommonCharacter.Name + " reports " + characters[randomStudent].Name + " for cheating but the claim is dismissed.");
                        Console.WriteLine();
                    }
                }
            }

            // This loop checks if any Students have fled
            for (int i = 0; i < 2; i++)
            {
                if (characters[i].HasLeftClassroom() == true && characters[i].Position == "student")
                {
                    characters.RemoveAt(i);
                    Console.WriteLine(characters[i].Name + " has received below a 25 and has left the classroom.");
                }
            }

            // This loop checks if any HonorsStudents have fled
            for (int i = 2; i < 4; i++)
            {
                if (characters[i].HasLeftClassroom() == true && characters[i].Position == "honors student")
                {
                    characters.RemoveAt(i);
                    Console.WriteLine(characters[i].Name + " has received below a 50 and has left the classroom.");
                }
            }

            break;
        }

您的while循环以break语句结尾。中断立即终止循环。如果你不希望你的循环终止，不要写一个break语句。

养成使用调试器逐行执行逐行代码的习惯，仔细检查每一行。养成这种习惯可以让你自己找到这样的缺陷。

我还注意到，有一个声明仅包含对Next的调用，但会丢弃结果。这几乎肯定是错的;该方法仅对其结果有用！

这里可能存在很多错误。再次，进入调试器，逐行，，并验证每行都完全符合您的意图。由于至少有一条线没有按照你的意思去做，这就是错误。

虽然循环过早结束
