Check if a character is a vowel or consonant?

Question

Is there a code to check if a character is a vowel or consonant? Some thing like char = IsVowel? Or need to hard code?

case ‘a’:
case ‘e’:
case ‘i’:
case ‘o’

Here's a function that works:

public static class CharacterExtentions
{
    public static bool IsVowel(this char c)
    {
        long x = (long)(char.ToUpper(c)) - 64;
        if (x*x*x*x*x - 51*x*x*x*x + 914*x*x*x - 6894*x*x + 20205*x - 14175 == 0) return true;
        else return false;
    }
}

Use it like:

char c = 'a';
if (c.IsVowel()) { // it's a Vowel!!! }

(Yes, it really works, but obviously, this is a joke answer. Don't downvote me. or whatever.)
