Generating Bitcoin addresses from a xpubkey

0 votes

I want to generate bitcoin address from a known xpubkey. The key I am using is here: https://blockchain.info/xpub/xpub6CUGRUonZSQ4TWtTMmzXdrXDtypWKiKrhko4egpiMZbpiaQL2jkwSB1icqYh2cfDfVxdx4df189oLKnC5fSwqPfgyP3hooxujYzAu3fDVmz

I am using the following code but when I execute it, get a 'Invalid point encoding 103' when I try to instantiate the ExtPubKey.

The code:

var pubkey = new ExtPubKey(Encoding.ASCII.GetBytes("6CUGRUonZSQ4TWtTMmzXdrXDtypWKiKrhko4egpiMZbpiaQL2jkwSB1icqYh2cfDfVxdx4df189oLKnC5fSwqPfgyP3hooxujYzAu3fDVmz"));

        Console.Writeline(pubkey.Derive(0).Derive(0).Derive(0).PubKey.GetAddress(Network.Main));

var pubkey = ExtPubKey.Parse("xpub6CUGRUonZSQ4TWtTMmzXdrXDtypWKiKrhko4egpiMZbpiaQL2jkwSB1icqYh2cfDfVxdx4df189oLKnC5fSwqPfgyP3hooxujYzAu3fDVmz");
var newAddress = pubkey.Derive(0).Derive(0).PubKey.GetAddress(Network.Main);
Console.WriteLine(newAddress);

It works and gives expected results.
