Note by digestible, I mean, the ability to put it into a project and
run with it. The reasons being:
a) line numbers (making the code not able to be compiled)
b) windows forms project
c) assumption of certain paths existing
It's extra effort to get people to reproduce and reduces the
likelihood of people pitching in on the answer as a result.
Note, none of these are huge barriers, but it makes it difficult to
just copy the code, dump it in a file and run with it.

Why not digestible? This type of question with clear short source code is
most likely to be answered.

Why are you adding the bytes as the field value? You should add the
fields as strings and you should be fine.
Also, note that most people won't respond to this kind of code
because it is not easily digestable.
