c#: Umrechnung arabische Zahlen–> römische Zahlen

Die folgende Methode habe ich beim c# Seminar in Hamburg erstellt:

private string roman(int number)
        {
            StringBuilder result = new StringBuilder();
            int[] digitsValues = { 1, 4, 5, 9, 10, 40, 50, 90, 100, 400, 500, 900, 1000 };
            string[] romanDigits = { &quot;I&quot;, &quot;IV&quot;, &quot;V&quot;, &quot;IX&quot;, &quot;X&quot;, &quot;XL&quot;, &quot;L&quot;, &quot;XC&quot;, &quot;C&quot;, &quot;CD&quot;, &quot;D&quot;, &quot;CM&quot;, &quot;M&quot; };
            while (number &gt; 0)
            {
                for (int i = digitsValues.Count() – 1; i &gt;= 0; i–)
                    if (number / digitsValues[i] &gt;= 1)
                    {
                        number -= digitsValues[i];
                        result.Append(romanDigits[i]);
                        break;
                    }
            }
            return result.ToString();
        }

private string roman(int number)

{

StringBuilder result = new StringBuilder();

int[] digitsValues = { 1, 4, 5, 9, 10, 40, 50, 90, 100, 400, 500, 900, 1000 };

string[] romanDigits = { "I", "IV", "V", "IX", "X", "XL", "L", "XC", "C", "CD", "D", "CM", "M" };

while (number > 0)

{

for (int i = digitsValues.Count() – 1; i >= 0; i—)

if (number / digitsValues[i] >= 1)

{

number -= digitsValues[i];

result.Append(romanDigits[i]);

break;

}

return result.ToString();

}
