This is something trivial, yet got me to think for a little. I had two checksums, one received from a client invoking a service, another one calculated once data sent into service is received. Checksums are plain arrays of bytes. I wanted to have comparison to be expressed as simple as possible. Quick google search brought me to a post that dealt with the same issue. But linq expression was too chatty and I think the solution was a bit muddy.

So I looked a bit more into linq options presented in the post, and this is what ended up using:

var matching = original_checksum.SequenceEqual(new_checksum);

Sometimes things are so simple, we tend to overcomplicate them.
