Problem on the conversion between byte array and string

[Stephanie Yao via .NET 247]

Hi, now I've done some practice on the encryption and decryption.

1, I get a encryption result, and show it in the textbox as a string, like this:
string regID = Encoding.UTF8.GetString(regBytes);
this.tbRID.Text = regID;\
here the length of the regBytes is 32;

2, I want to decrypt the string in another function, so I did this:
string regID = this.tbRID.Text;
byte[] regBytes = Encoding.UTF8.GetBytes(regID);
But here the length of the regBytes is 20, so can anyone tell me how to get the missing data?
