C# 打印拼写的数字（int）值

有没有现成的方法可以用C#来拼写int？例如，如果我有：

int a = 53;

我想打印：

"fifty three"

不是

如果没有，有没有人能举例说明如何做到这一点

---

谢谢

你必须自己编写代码。如果不得不猜测的话，我会说它不在框架中，因为它几乎不可能本地化（这不仅仅是数字的名称：词序、连字符规则等等）

---

这让我想起了往事，因为这是我大学第一门编程课程的作业，所以用英语写一篇应该不会太难。

如果其他方法都失败了，请询问比尔·盖茨和他的团队。这应该让你开始

提供了将整数转换为单词的解决方案

下面是将数字转换为数字的代码 语言

和

objnumber.changeNumericToWord（100）

使用该函数，您将获得数字
变成文字

他使用实例方法，但您可以使这些方法成为静态的，这里有一个额外的方法，只是为了好玩

是的，有一种方法可以做到这一点。该项目有一个带有“拼写”选项的基于规则的数字格式化程序。它甚至支持完全本地化

唯一的障碍是它只能在C、C++和java中使用。该项目中有一项计划（针对.NET Framework和.NET标准1.6），但此功能和许多其他功能尚未移植。然而，一项贡献可以很好地解决这个问题

还有一个应该能够围绕ICU4C库自动生成一个C#wrapper库，但我还没有尝试过

可用于其他编程语言。
本地化将是一件痛苦的事情——我只是在想法语“98”四行（字面意思是“4218”）的麻烦本地化通常是一件痛苦的事情，但对于一些小的定制，如连字符，这确实应该是开箱即用的。您能告诉我如何通过采用OOP概念、更干净的代码和TDD来实现这一点吗。
