Answer 1

private static string GetStringFromAsciiHex(String input)
{
    if (input.Length % 2 != 0)
        throw new ArgumentException("input");

    byte[] bytes = new byte[input.Length / 2];

    for (int i = 0; i < input.Length; i += 2)
    {
        // Split the string into two-bytes strings which represent a hexadecimal value, and convert each value to a byte
        String hex = input.Substring(i, 2);
        bytes[i/2] = Convert.ToByte(hex, 16);                
    }

    return System.Text.ASCIIEncoding.ASCII.GetString(bytes);
}
