How to convert a String to a Hex Byte Array? [duplicate]

Answer 1

Do you need this?

static class HexStringConverter
{
    public static byte[] ToByteArray(String HexString)
    {
        int NumberChars = HexString.Length;
        byte[] bytes = new byte[NumberChars / 2];
        for (int i = 0; i < NumberChars; i += 2)
        {
            bytes[i / 2] = Convert.ToByte(HexString.Substring(i, 2), 16);
        }
        return bytes;
    }
}

Hope it helps.
