Generated codes do not match Google Authenticator results

I am using this code:

string secret = "KREQPD7NXSGO3T3B";
while (true)
{
    byte[] secretBytes = new Base32Encoder().Decode(secret);
    OtpNet.Totp totp = new OtpNet.Totp(secretBytes);
    string twoFactorCode = totp.ComputeTotp();

    Console.WriteLine("Two factor code: " + twoFactorCode);

    System.Threading.Thread.Sleep(2000);
}

Now if you take that same string (for secret) and put it in to Google Authenticator manually, you will notice that this code generates different keys. On the otherhand, if I use a different value for secret (eg “uhj34qsyuwftzji4qq6k3c3wnstdb57m”) then both the values generated by OtpNet and Google Authenticator will match.

What am I doing wrong?

I just got it. The way to get bytes[] is wrong. I need to use var secretKey = Base32Encoding.ToBytes(OtpSecretKey); Then OtpNet and Google Authenticator will match.
