Question

I have a developer key

 byte[] key = new Byte[]
            {
                0x01, 0x42, 0xA0, 0xE1, 0x5E, 0xEE, 0xA7, 0x01, 0x71, 0x9A, 0xCB, 0xAB, 0x58, 0xEB, 0xED, 0x44...

that I want to store in my web.config, can I do something like as follows

<add key="spotify-devkey" value="0x01, 0x42, 0xA0, 0xE1, 0x5E, 0xEE, 0xA7, 0x01, 0x71, 0x9A, 0xCB, 0xAB, 0x58, 0xEB, 0xED, 0x44,...

and if I can do it this easily what code would I need to get the byte array from the stored string?

Answer 1

string value = ... // value from config file.
byte[] key = value.Split(new[] {','}).Select(s => Convert.ToByte(s, 16))
                                     .ToArray();
