The vars declared outside are not. I was wondering if you were doing that deliberately, instead of making it a fixed size outside the loop and say clearing it inside rather than re-allocating every time.

Basically, when you convert from a byte array -> string, you have two copies of the same data (one for the byte array and one for the string) in memory. What exactly are you doing? You are typically better off chunking and reading smaller amounts of data at a time. Use something like a StreamWriter over a stream to automatically handles the byte -> text conversion.
