我的不同数字程序不起作用

Question

我正在制作一个程序，每次程序检查它不是一个不同的数字时，都会将 +1 添加到一年，直到它是一个。我不知道为什么它不起作用，我们将不胜感激。昨天回家的时候还在用，今天就不想用了。

        private void yearInput_TextChanged(object sender, EventArgs e) // Year Input Textbox \
        {

        }

        public bool exception;
        public static int yearInputInt;
        public static strng yearInputString;

        private void yearInputConfirm_Click(object sender, EventArgs e) // Year Input Confirm Button \
        {
            exception = false;
            yearInputString = yearInput.Text;
            yearInputInt = Int32.Parse(yearInputString);
            if (yearInputString.Length == 2)
            {
                while (yearInputString.Substring(0, 1) == yearInputString.Substring(1, 1))
                {
                    yearInputInt = yearInputInt + 1;
                    yearInputString = yearInputInt.ToString();
                    if (yearInputString.Length == 3)
                    {
                        while (yearInputString.Substring(0, 1) == yearInputString.Substring(1, 1) || yearInputString.Substring(0, 1) == yearInputString.Substring(2, 1) || yearInputString.Substring(1, 1) == yearInputString.Substring(2, 1))
                        {
                            yearInputInt = yearInputInt + 1;
                            yearInputString = yearInputInt.ToString();
                        }
                    }
                }
            }

            if (yearInputString.Length == 3)
            {
                while (yearInputString.Substring(0, 1) == yearInputString.Substring(1, 1) || yearInputString.Substring(0, 1) == yearInputString.Substring(2, 1) || yearInputString.Substring(1, 1) == yearInputString.Substring(2, 1))
                {
                    yearInputInt = yearInputInt + 1;
                    yearInputString = yearInputInt.ToString();
                    if (yearInputString.Length == 4)
                    {
                        while (yearInputString.Substring(0, 1) == yearInputString.Substring(1, 1) || yearInputString.Substring(0, 1) == yearInputString.Substring(2, 1) || yearInputString.Substring(0, 1) == yearInputString.Substring(3, 1) || yearInputString.Substring(1, 1) == yearInputString.Substring(2, 1) || yearInputString.Substring(1, 1) == yearInputString.Substring(3, 1) || yearInputString.Substring(2, 1) == yearInputString.Substring(3, 1))
                        {
                            yearInputInt = yearInputInt + 1;
                            yearInputString = yearInputInt.ToString();
                        }
                    }
                }
            }

            if (yearInputString.Length == 4)
            {
                while (yearInputString.Substring(0, 1) == yearInputString.Substring(1, 1) || yearInputString.Substring(0, 1) == yearInputString.Substring(2, 1) || yearInputString.Substring(0, 1) == yearInputString.Substring(3, 1) || yearInputString.Substring(1, 1) == yearInputString.Substring (2, 1) || yearInputString.Substring(1, 1) == yearInputString.Substring(3, 1) || yearInputString.Substring(2, 1) == yearInputString.Substring(3, 1))
                {
                    yearInputInt = yearInputInt + 1;
                    yearInputString = yearInputInt.ToString();
                    if (yearInputString.Length == 5)
                    {
                        while (yearInputString.Substring(0, 1) == yearInputString.Substring(1, 1) || yearInputString.Substring(0, 1) == yearInputString.Substring(2, 1) || yearInputString.Substring(0, 1) == yearInputString.Substring(3, 1) || yearInputString.Substring(0, 1) == yearInputString.Substring(4, 1) || yearInputString.Substring(1, 1) == yearInputString.Substring(2, 1) || yearInputString.Substring(1, 1) == yearInputString.Substring(3, 1) || yearInputString.Substring(3, 1) == yearInputString.Substring(4, 1) || yearInputString.Substring(2, 1) == yearInputString.Substring(3, 1) || yearInputString.Substring(2, 1) == yearInputString.Substring(4, 1) || yearInputString.Substring(3, 1) == yearInputString.Substring(4, 1))
                        {
                            yearInputInt = yearInputInt + 1;
                            yearInputString = yearInputInt.ToString();
                        }
                    }
                }
            }

            if (yearInputString.Length == 5)
            {
                while (yearInputString.Substring(0, 1) == yearInputString.Substring(1, 1) || yearInputString.Substring(0, 1) == yearInputString.Substring(2, 1) || yearInputString.Substring(0, 1) == yearInputString.Substring(3, 1) || yearInputString.Substring(0, 1) == yearInputString.Substring(4, 1) || yearInputString.Substring(1, 1) == yearInputString.Substring(2, 1) || yearInputString.Substring(1, 1) == yearInputString.Substring(3, 1) || yearInputString.Substring(3, 1) == yearInputString.Substring(4, 1) || yearInputString.Substring(2, 1) == yearInputString.Substring(3, 1) || yearInputString.Substring(2, 1) == yearInputString.Substring(4, 1) || yearInputString.Substring(3, 1) == yearInputString.Substring(4, 1))

                    yearInputInt = yearInputInt + 1;
                    yearInputString = yearInputInt.ToString();
                }
            }
            label2.Text = yearInputString;
        }

当我在 Visual Studio 中编译时，编译过程崩溃并得到错误：

1>H:\profile\desktop\C#\distinctDigitsRevamped\distinctDigitsRev\distinctDigitsR‌ev\Form1.cs(28,23,28,28): error CS0246: The type or namespace name 'strng' could not be found (are you missing a using directive or an assembly reference?)

Answer 1

变量声明yearInputString。请注意，您从 string.

中缺少 i

Answer 2

在第 8 行，字符串拼写错误。

 public static strng yearInputString;

该行应该是：

 public static string yearInputString;
