Is there a library or a class/function that I can use to convert an integer to it\'s verbal representation?
Example input:
4,567,788`
Example output:
Four million, Five hundred sixty-seven thousand, seven hundred eighty-eight

回答1:
if you use the code found in: converting numbers in to words C# and you need it for decimal numbers, here is how to do it:
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;
}

Currently the best, most robust, library for this is definitely Humanizer. It\'s open sourced and available as a nuget:
Console.WriteLine(4567788.ToWords()); // => four million five hundred and sixty-seven thousand seven hundred and eighty-eight
It also has a wide range of tools solving the small problems every application has with strings, enums, DateTimes, TimeSpans and so forth, and supports many different languages.
Console.WriteLine(4567788.ToOrdinalWords().Underscore().Hyphenate().ApplyCase(LetterCasing.AllCaps)); // => FOUR-MILLION-FIVE-HUNDRED-AND-SIXTY-SEVEN-THOUSAND-SEVEN-HUNDRED-AND-EIGHTY-EIGHTH

Fully recursive version:
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\" };
public static string ToWords(decimal number)
{
if (number < 0)
return \"negative \" + ToWords(Math.Abs(number));
int intPortion = (int)number;
int decPortion = (int)((number - intPortion) * (decimal) 100);
return string.Format(\"{0} dollars and {1} cents\", ToWords(intPortion), ToWords(decPortion));
}
private static string ToWords(int number, string appendScale = \"\")
{
string numString = \"\";
if (number < 100)
{
if (number < 20)
numString = ones[number];
else
{
numString = tens[number / 10];
if ((number % 10) > 0)
numString += \"-\" + ones[number % 10];
}
}
else
{
int pow = 0;
string powStr = \"\";
if (number < 1000) // number is between 100 and 1000
{
pow = 100;
powStr = thous[0];
}
else // find the scale of the number
{
int log = (int)Math.Log(number, 1000);
pow = (int)Math.Pow(1000, log);
powStr = thous[log];
}
numString = string.Format(\"{0} {1}\", ToWords(number / pow, powStr), ToWords(number % pow)).Trim();
}
return string.Format(\"{0} {1}\", numString, appendScale).Trim();
}
Current works up to the (short scale) quadrillions. Additional support (for larger numbers, or for the long scale) can be added simply by changing the thous variable.
Perhaps, needlessly complex (the special case for hundreds bugs me a little), given that modifying the non-recursive version is also fairly simple.

Solution that takes up less code.
The most important part is only couple lines:
static Func<long, string> remainder = t => t > 0 ? \" \" + ToEN(t) : \"\";
public static string ToEN(this long val, double d = 20, long th = 20)
{
switch ((long)d)
{
case 20: return val >= d ? ToEN(val, 1e2) : en[val];
case 100: return val >= d ? ToEN(val, 1e3, 100) : en[val / 10 * 10] + remainder(val % 10);
default: return val >= d ? ToEN(val, d * 1e3,(long)d) : ToEN(val / th) + \" \" + en[th] + remainder(val % th);
}
}
