Some string utilities

// Removes special characters from a string
public string RemoveSpecialChars(string input, string specialChars)
{
    return Regex.Replace(input, specialChars, string.Empty);
}

// Reverses a string
public string Reverse(string input)
{
	if (string.IsNullOrWhiteSpace(input))
	{
		return input;
	}

	char[] array = input.ToCharArray();
	Array.Reverse(array);
	return new String(array);
}
