I wrote this code for something similar I was doing, feel free to rip
it off or copy the regular expressions:
input = Regex.Replace(input, @"[\xC0-\xC5\xE0-\xE5]", "a"); //Replace with "a"
input = Regex.Replace(input, @"[\xC8-\xCB\xE8-\xEB]", "e"); //Replace with "e"
input = Regex.Replace(input, @"[\xCC-\xCF\xEC-\xEF]", "i"); //Replace with "i"
input = Regex.Replace(input, @"[\xD1\xF1]", "n"); //Replace with "n"
input = Regex.Replace(input, @"[\xD2-\xD6\xF2-\xF6]", "o"); //Replace with "o"
input = Regex.Replace(input, @"[\xD9-\xDC\xF9-\xFC]", "u"); //Replace with "u"
input = Regex.Replace(input, @"[\xDD\xDF\xFF]", "y"); //Replace with "y"
