目前，最好，最强大的库绝对是Humanizer。它是开源的，可以作为nuget使用：
Console.WriteLine(4567788.ToWords()); // => four million five hundred and sixty-seven thousand seven hundred and eighty-eight
它还提供了广泛的工具，可以解决每个应用程序在string，enum，DateTime，TimeSpan等方面遇到的小问题，并支持许多不同的语言。
Console.WriteLine(4567788.ToOrdinalWords().Underscore().Hyphenate().ApplyCase(LetterCasing.AllCaps)); // => FOUR-MILLION-FIVE-HUNDRED-AND-SIXTY-SEVEN-THOUSAND-SEVEN-HUNDRED-AND-EIGHTY-EIGHTH
答案 1 :(得分：28)
如果您使用以下代码： converting numbers in to words C# 你需要十进制数字，这是如何做到的：
public string DecimalToWords(decimal number)
{
if (number == 0)
return "zero";
if (number < 0)
return "minus " + DecimalToWords(Math.Abs(number));
string words = "";
int intPortion = (int)number;
decimal fraction = (number - intPortion)*100;
int decPortion = (int)fraction;
words = NumericToWords(intPortion);
if (decPortion > 0)
{
words += " and ";
words += NumericToWords(decPortion);
}
return words;
}

完全递归版本：
private static string[] ones = {
"zero", "one", "two", "three", "four", "five", "six", "seven", "eight", "nine",
"ten", "eleven", "twelve", "thirteen", "fourteen", "fifteen", "sixteen", "seventeen", "eighteen", "nineteen",
};
private static string[] tens = { "zero", "ten", "twenty", "thirty", "forty", "fifty", "sixty", "seventy", "eighty", "ninety" };
private static string[] thous = { "hundred", "thousand", "million", "billion", "trillion", "quadrillion" };
private static string fmt_negative = "negative {0}";
private static string fmt_dollars_and_cents = "{0} dollars and {1} cents";
private static string fmt_tens_ones = "{0}-{1}"; // e.g. for twenty-one, thirty-two etc. You might want to use an en-dash or em-dash instead of a hyphen.
private static string fmt_large_small = "{0} {1}"; // stitches together the large and small part of a number, like "{three thousand} {five hundred forty two}"
private static string fmt_amount_scale = "{0} {1}"; // adds the scale to the number, e.g. "{three} {million}";
public static string ToWords(decimal number) {
if (number < 0)
return string.format(fmt_negative, ToWords(Math.Abs(number)));
int intPortion = (int)number;
int decPortion = (int)((number - intPortion) * (decimal) 100);
return string.Format(fmt_dollars_and_cents, ToWords(intPortion), ToWords(decPortion));
}
private static string ToWords(int number, string appendScale = "") {
string numString = "";
// if the number is less than one hundred, then we're mostly just pulling out constants from the ones and tens dictionaries
if (number < 100) {
if (number < 20)
numString = ones[number];
else {
numString = tens[number / 10];
if ((number % 10) > 0)
numString = string.Format(fmt_tens_ones, numString, ones[number % 10]);
}
} else {
int pow = 0; // we'll divide the number by pow to figure out the next chunk
string powStr = ""; // powStr will be the scale that we append to the string e.g. "hundred", "thousand", etc.
if (number < 1000) { // number is between 100 and 1000
pow = 100; // so we'll be dividing by one hundred
powStr = thous[0]; // and appending the string "hundred"
} else { // find the scale of the number
// log will be 1, 2, 3 for 1_000, 1_000_000, 1_000_000_000, etc.
int log = (int)Math.Log(number, 1000);
// pow will be 1_000, 1_000_000, 1_000_000_000 etc.
pow = (int)Math.Pow(1000, log);
// powStr will be thousand, million, billion etc.
powStr = thous[log];
}
// we take the quotient and the remainder after dividing by pow, and call ToWords on each to handle cases like "{five thousand} {thirty two}" (curly brackets added for emphasis)
numString = string.Format(fmt_large_small, ToWords(number / pow, powStr), ToWords(number % pow)).Trim();
}
// and after all of this, if we were passed in a scale from above, we append it to the current number "{five} {thousand}"
return string.Format(fmt_amount_scale, numString, appendScale).Trim();
}
电流达到（短程）四度。只需更改thous变量即可添加其他支持（对于较大的数字或long scale）。

我的任务是创建一个WEB API，使用C＃将数字转换为单词。
可以是48小时内的整数或小数点。
调用将来自使用Ajax Post方法的前端应用程序，并将转换后的结果返回到网页中。
我已在GitHub上公开分享该项目以供参考：https://github.com/marvinglennlacuna/NumbersToWordsConverter.Api
通过以下技术实现：
- MVC结构化
- API控制器
- 服务
- 模型
- 错误处理
- 使用MSTest进行单元测试
- 代码覆盖率 - 98％
- Jquery的
- 目的
- 先决条件
- 功能要求
- 流程图和输出
关于以下内容的技术文档：
**网页结果（US-001）**
US-001通过网页流程将数字转换为单词
US-001通过网页输出将数字转换为单词
通过Postman的结果（US-002）
US-002 - 通过邮递员流程将数字转换为单词
