In 1 line, not very efficient but works:

public string RomanNumeralFrom(int number)
{
    return
        new string('I', number)
            .Replace(new string('I', 1000), "M")
            .Replace(new string('I', 900), "CM")
            .Replace(new string('I', 500), "D")
            .Replace(new string('I', 400), "CD")
            .Replace(new string('I', 100), "C")
            .Replace(new string('I', 90), "XC")
            .Replace(new string('I', 50), "L")
            .Replace(new string('I', 40), "XL")
            .Replace(new string('I', 10), "X")
            .Replace(new string('I', 9), "IX")
            .Replace(new string('I', 5), "V")
            .Replace(new string('I', 4), "IV");
}
