即使此问题已经发布并在之前得到解答。我想要帮助我的代码。任务是将数字转换为0到1000万的单词。我试图用我的代码使用GUI来做到这一点，问题是它根本没有返回答案。任何人都可以帮助我确定代码可能存在的问题。
以下代码：
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 > 10)
{
if (number > 10 && number < 20)
{
for (int x = 11; x < 20; x++)
{
if (number == x)
{
ConvertedNumber = teens[x - 11];
}
}
}
else
{
number -= 10;
Count++;
}
ConvertedNumber += tens[Count - 1];
}
}
else if (number >= 100 && number < 1000)
{
while (number > 100)
{
number -= 100;
Count++;
}
ConvertedNumber += ones[Count - 1] + moreThenTens[0];
}
else if (number >= 1000 && number < 10000)
{
while (number > 1000)
{
number -= 1000;
Count++;
}
ConvertedNumber += ones[Count - 1] + moreThenTens[1];
}
else if (number >= 10000 && number < 100000)
{
while (number > 10000)
{
if (number < 20000)
{
number -= 10000;
Count++;
}
else if (number >= 20000)
{
number -= 10000;
Count++;
}
}
if (Count >= 1)
{
if (number < 1000)
{
ConvertedNumber += tens[0] + moreThenTens[1];
}
else if (number >= 1000)
{
ConvertedNumber += teens[Count - 1] + moreThenTens[1];
}
}
else if (Count > 1)
{
ConvertedNumber += tens[Count - 1] + moreThenTens[1];
}
}
else if (number >= 100000 && number < 1000000)
{
while (number > 100000)
{
number -= 100000;
Count++;
}
ConvertedNumber += ones[Count - 1] + moreThenTens[0] + moreThenTens[1];
}
else if (number >= 1000000 && number < 10000000)
{
while (number > 1000000)
{
number -= 1000000;
Count++;
}
ConvertedNumber += ones[Count - 1] + moreThenTens[2];
}
else if (number == 10000000)
{
while (number > 10000000)

}
ConvertedNumber += tens[0] + moreThenTens[2];
}
}
txtConvertedNumber.Text = ConvertedNumber;
}
}

while (number >= 0)
好像你的代码正在创建一个无限循环。举个例子：
if (number == 0)
{
ConvertedNumber = "Zero";
}
这不会退出你的循环，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;
}

这可能很有用
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;
}
答案 2 :(得分：1)
你应该在while循环之前检查数字是否为零
if ( number == 0 )
ConvertedNumber= "Zero" ;
然后按如下所示修改while
while(number > 0)
答案 3 :(得分：1)
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]));

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];
}
}
}

这也可以使您的代码更易于调试/跟踪。
while (NumberExists(ConvertedNumber, number))
{
...
}
将此方法放在与nameSpace相同的btnConvertToText_Click。
private static bool NumberExists(string convertedNumber, int number)
{
if (convertedNumber == " " && number != null)
{
return true;
}
else
return false;
}
一般情况下，我建议不要在代码中添加幻数，例如+ 1s或-1s。它可以使调试更多的苦差事。如果你必须这样做以获得一些工作，试着找出原因并尽快重写。绝对在开始其他方法之前。
