Wie kann ich eine Ganzzahl in ihre verbale Darstellung konvertieren?
Gibt es eine Bibliothek oder eine Klasse/Funktion, mit der ich eine Ganzzahl in ihre verbale Darstellung konvertieren kann?
Beispieleingabe:
4,567,788`
Beispielausgabe:
Vier Millionen, fünfhundertsiebenundsechzigtausend, siebenhundertachtundachtzig
wenn Sie den Code verwenden, der in: Zahlen in die Wörter C # umgewandelt wird, und Sie ihn für Dezimalzahlen benötigen, gehen Sie wie folgt vor:
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;
}
Derzeit ist die beste und robusteste Bibliothek definitiv Humanizer . Es ist Open Source und als Nuget erhältlich:
Console.WriteLine(4567788.ToWords()); // => four million five hundred and sixty-seven thousand seven hundred and eighty-eight
Es hat auch eine Vielzahl von Tools, die die kleinen Probleme lösen, die jede Anwendung mit strings, enums, DateTimes, TimeSpans usw. hat, und viele verschiedene Sprachen unterstützt.
Console.WriteLine(4567788.ToOrdinalWords().Underscore().Hyphenate().ApplyCase(LetterCasing.AllCaps)); // => FOUR-MILLION-FIVE-HUNDRED-AND-SIXTY-SEVEN-THOUSAND-SEVEN-HUNDRED-AND-EIGHTY-EIGHTH
Vollrekursive 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();
}
Aktuelle Arbeiten bis zu den (kurzen Skalen) Billiarden. Zusätzliche Unterstützung (für größere Zahlen oder für die lange Skala ) kann einfach durch Ändern der Variablen thous hinzugefügt werden.
Vielleicht unnötig komplex (der Spezialfall für Hunderte macht mich ein wenig), da die Änderung der nicht rekursiven Version auch recht einfach ist.
Hier ist die spanische Version:
public static string numeroALetras(int number)
{
if (number == 0)
return "cero";
if (number < 0)
return "menos " + numeroALetras(Math.Abs(number));
string words = "";
if ((number / 1000000) > 0)
{
words += numeroALetras(number / 1000000) + " millón ";
number %= 1000000;
}
if ((number / 1000) > 0)
{
words += (number / 1000) == 1? "mil ": numeroALetras(number / 1000) + " mil ";

else {

Ich wurde beauftragt, eine WEB-API zu erstellen, die mithilfe von C # Zahlen in Wörter konvertiert.
Kann in 48 Stunden ganzzahlig oder mit Dezimalstellen sein.
Der Aufruf wird von einer Front-End-Anwendung mit Ajax Post-Methode kommen und das konvertierte Ergebnis auf der Webseite zurückgeben.
Ich habe dieses Projekt im GitHub öffentlich zur Referenz freigegeben: https://github.com/marvinglennlacuna/NumbersToWordsConverter.Api
Mit der folgenden technischen Implementierung in platzieren:
- MVC strukturiert
- API-Controller
- Bedienung
- Modell
- Fehlerbehandlung
- Unit-Test mit MSTest
- Code-Abdeckung - 98%
- Jquery
Und mit technischer Dokumentation zu folgenden Themen:
- Zweck
- Voraussetzungen
- Funktionsanforderungen
- Prozessdiagramm und Ausgabe
** Ergebnis über Webseite (US-001) **
US-001 Konvertieren von Zahlen in Wörter über den Webseitenprozess
US-001 Konvertieren von Zahlen in Wörter über die Ausgabe von Webseiten
Ergebnis via Postman (US-002)
US-002 - Zahlen in Wörter über den Postman-Prozess konvertieren
US-002 - Zahlen in Wörter über Postman-Ausgabe konvertieren
Ich denke, es lohnt sich, eine funktionierende Lösung mitzuteilen, falls Sie sie als Referenz für Interview/Code-Test/Schule oder nur zum Spaß benötigen.
Prost, Marvin

Lösung, die weniger Code beansprucht.
Der wichtigste Teil sind nur paarweise:
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);
}
}
