即使这个问题之前已经发布并回答过。我需要有关我的代码的帮助。任务是将一个数字转换为从 0 到 1000 万的单词。我试图用我的代码使用 GUI 来做到这一点，问题是它根本不返回答案。任何人都可以帮助我确定代码上的问题可能是什么。

下面的代码：

private void btnConvertToText_Click(object sender, EventArgs e)
    {
        string ConvertedNumber = " ";
        int number = Convert.ToInt32(txtNumber.Text);
        int Count = 0;

           string [] ones =  {" One ", " Two ", " Three ", " Four ", " Five ", " Six ", " Seven ", " Eight ", " Nine "};
           string [] teens= {" Eleven ", " Twelve ", " Thirteen ", " Fourtte n ", " Fifteen ", " Sixteen ", " Seventeen ", " Eighteen ", " Nineteen "};
           string [] tens = {" Ten ", " Twenty ", " Thirty ", " Fourty ", " Fifty ", " Sixty ", " Seventy ", " Eighty ", " Ninenty "};
           string [] moreThenTens = {" hundred ", " thousand ", " million "};

           while (number >= 0)
           {
               if (number == 0)
               {
                   ConvertedNumber = "Zero";
               }

              else if (number < 10)
               {
                   for (int Counter = 1; Counter < 10; Counter++)
                   {
                       ConvertedNumber += ones[Counter-1];
                   }
               }

               else if (number >= 10 && number < 100)

while (number >= 0)

您的代码似乎正在创建一个无限循环。举个例子：

if (number == 0)
{
    ConvertedNumber = "Zero";
}

这不会退出您的循环，因此永远不会到达

txtConvertedNumber.Text = ConvertedNumber;

使用支票转换您的号码，例如：

if (number == 0)
{
    ConvertedNumber = "Zero";
    number = -1;
}

这可能有用 

public static string NumberToWords(int number)
    {
        if (number == 0)
            return "Zero";

        if (number < 0)
            return "Minus " + NumberToWords(Math.Abs(number));

        string words = "";

        if ((number / 1000000) > 0)
        {
            words += NumberToWords(number / 1000000) + " Million ";
            number %= 1000000;
        }

        if ((number / 1000) > 0)
        {
            words += NumberToWords(number / 1000) + " Thousand ";
            number %= 1000;
        }

        if ((number / 100) > 0)
        {
            words += NumberToWords(number / 100) + " Hundred ";
            number %= 100;
        }

        if (number > 0)
        {
            if (words != "")
                words += "and ";

            var unitsMap = new[] { "Zero", "One", "Two", "Three", "Four", "Five", "Six", "Seven", "Eight", "Nine", "Ten", "Eleven", "Twelve", "Thirteen", "Fourteen", "Fifteen", "Sixteen", "Seventeen", "Eighteen", "Nineteen" };
            var tensMap = new[] { "zero", "Ten", "Twenty", "Thirty", "Forty", "Fifty", "Sixty", "Seventy", "Eighty", "Ninety" };

            if (number < 20)
                words += unitsMap[number];
            else
            {
                words += tensMap[number / 10];
                if ((number % 10) > 0)
                    words += "-" + unitsMap[number % 10];
            }
        }

        return words;
    }

您应该在 while 循环之前检查数字是否为零

 if ( number == 0 )
      ConvertedNumber= "Zero" ;

然后修改while如下

while(number > 0)

这可能有助于十进制数

string[] number = Number1.ToString().Split('.');

String Word=NumberToWords(convert.toInt64(number[0])) + " AND " +     NumberToWords(convert.toInt64(number[1]));

这也可以使您的代码更易于调试/遵循。

while (NumberExists(ConvertedNumber, number))
{
   ...
}

将此方法nameSpace与btnConvertToText_Click.

    private static bool NumberExists(string convertedNumber, int number)
    {
        if (convertedNumber == " " && number != null)
        {
            return true;
        }
        else
            return false;
    }

一般来说，我建议不要在您的代码中添加幻数，例如 +1s 或 -1s。它可以使调试更加繁琐。如果您必须这样做才能使某些东西起作用，请尝试找出原因并尽快重写它。绝对是在使用其他方法之前。

似乎它陷入了循环..我在这里检查了青少年数字部分，好像你忘记将数字减少到小于零或零

                else if (number >= 10 && number < 100)
              {
              if(number > 10)
              {
                  if (number > 10 && number < 20)
                  {
                      for (int x = 11; x < 20; x++)
                      {
                          if (number == x)
                          {
                              ConvertedNumber += teens[x - 11];

                          }
                      }
                      ***number -= 100;***
                  }

                  else
                  {
                      number -= 10;
                      Count++;
                      ConvertedNumber += tens[Count - 1];
                  }
