通常我会string.Format()用来获取格式化的字符串。
但我要求所有金额都应打印为文本而不是数字。
即类似的东西：
Format(3000, "us"); // => Resulting text: "three thousand dollars"

是否有可以处理的 .NET 库（俄语是强制性的）？
简短的回答：没有。
您必须自己编写，但我建议您看一下以下内容： 将数字转换为单词 C#， 如何将整数转换为其口头表示？正如其中之一所说，查看项目 Euler 问题编号 17并将其用于更广泛的谷歌搜索。
除此之外，您还有货币名称的问题，应该'us'表示货币或语言，甚至两者兼而有之？加元和美元有区别吗？
例如这是内置的：
// Gives USD
var ISOCode = System.Globalization.RegionInfo.RegionInfo("US").ISOCurrencySymbol
// Gives $
var symbol = System.Globalization.RegionInfo.RegionInfo("US").CurrencySymbol
// Gives USD Dollar (i believe :))
var nameUSDENG = System.Globalization.RegionInfo.RegionInfo("US").CurrencyEnglishName
// Gives Svensk Krona
var nameSEKSWE = System.Globalization.RegionInfo.RegionInfo("SE").CurrencyNativeName
// Gives Swedish Krona
var nameSEKENG = System.Globalization.RegionInfo.RegionInfo("SE").CurrencyEnglishName
我建议你从那里开始，看看这条路会把你带到哪里。

有一个成熟的库可以满足您的需要。这叫人性化。
你可以在这里看到它的内容：NuGet 本周包：Humanizer 使 .NET 数据类型更人性化
如您所见，它可以满足您的需要以及更多功能。它有很多本地化。
一些例子：
1.ToWords() => "one"
10.ToWords() => "ten"
11.ToWords() => "eleven"
122.ToWords() => "one hundred and twenty-two"
3501.ToWords() => "three thousand five hundred and one"
您还可以将第二个参数 GrammaticalGender 传递给 ToWords，以指定数字应以哪种性别输出。
1.ToWords(GrammaticalGender.Masculine) => "один"
1.ToWords(GrammaticalGender.Feminine) => "одна"
1.ToWords(GrammaticalGender.Neuter) => "одно"

我环顾四周，但找不到合适的版本来转换为英语货币，因此我将一些合并到此解决方案中：
public static class NumberExtensions
{
public static String toCurrency(this double number, String major, String minor, String endStr, int minorLength)
{
return ((decimal)number).toCurrency(major, minor, endStr, minorLength);
}
public static String toCurrency(this decimal number, String major, String minor, String endStr, int minorLength)
{
if (String.IsNullOrWhiteSpace(major)) throw new Exception("Must specify major currency");
if (String.IsNullOrWhiteSpace(minor)) throw new Exception("Must specify minor currency");
String numb = number.ToString();
String val = "", wholeNo = numb, points = "", andStr = major, pointStr = "";
int decimalPlace = numb.IndexOf(".");
if (decimalPlace > 0)
{
wholeNo = numb.Substring(0, decimalPlace);
points = numb.Substring(decimalPlace + 1);
if (points.Length > minorLength) throw new Exception("Incorrect format");
if (Convert.ToInt32(points) > 0)
{
andStr = major + " and";
endStr = minor + " " + endStr;
pointStr = Int32.Parse(points.Length == 1 ? points + "0" : points).toWords();
}
}
if (String.IsNullOrWhiteSpace(pointStr))
{
if (endStr == minor + " " || endStr == null)
{
val = String.Format("{0} {1}", Int32.Parse(wholeNo).toWords().Trim(), andStr.Trim());
}
else
{
val = String.Format("{0} {1} {2}", Int32.Parse(wholeNo).toWords().Trim(), andStr.Trim(), endStr.Trim());
}
}
else
{
val = String.Format("{0} {1} {2} {3}", Int32.Parse(wholeNo).toWords().Trim(), andStr.Trim(), pointStr.Trim(), endStr.Trim());
}
return val;
}
public static string toWords(this int number)
{
if (number == 0)
return "Zero";
if (number < 0)
return "minus " + Math.Abs(number).toWords();
string words = "";
if ((number / 1000000) > 0)
{
words += (number / 1000000).toWords().TrimEnd() + " Million ";
number %= 1000000;
}
if ((number / 1000) > 0)
{
words += (number / 1000).toWords().TrimEnd() + " Thousand ";
number %= 1000;
}
if ((number / 100) > 0)
{
words += (number / 100).toWords().TrimEnd() + " 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;
}
}
这是单元测试：

我还没有测试过，但也许这会解决你的问题？
它说它也支持俄语。
从包装描述：
数字到文本转换器。支持的语言 英语 俄语 西班牙语 土耳其语
用法：
var number = 123456.78
var moneyText = number.ToText("usd", "en");
var number = 123456.78;
var moneyText = number.ToText(Nut.Currency.USD, Nut.Language.English);
var number = 123456.78;
var options = new Nut.Options {
MainUnitNotConvertedToText = true,
SubUnitNotConvertedToText = true,
MainUnitFirstCharUpper = true,
SubUnitFirstCharUpper = true,
CurrencyFirstCharUpper = true,
SubUnitZeroNotDisplayed = true
}
var moneyText = number.ToText(Nut.Currency.USD, Nut.Language.English, options);

对于俄语，您可以使用我的库：https
://github.com/nick-buhro/NumToWords
它也可以在 nuget 上获得：https ://www.nuget.org/packages/NickBuhro.NumToWords
例子：
var unit = new UnitOfMeasure(Gender.Masculine, "доллар", "доллара", "долларов");
var text = RussianConverter.Format(3000, unit);
Console.WriteLine(text);
// Output: три тысячи долларов
