This should be the simplest solution.

public string IntToRoman(int num)
{
    var result = string.Empty;
    var map = new Dictionary
    {
        {"M", 1000 },
        {"CM", 900},
        {"D", 500},
        {"CD", 400},
        {"C", 100},
        {"XC", 90},
        {"L", 50},
        {"XL", 40},
        {"X", 10},
        {"IX", 9},
        {"V", 5},
        {"IV", 4},
        {"I", 1}
    };
    foreach (var pair in map)
    {
        result += string.Join(string.Empty, Enumerable.Repeat(pair.Key, num / pair.Value));
        num %= pair.Value;
    }
    return result;
}
