Answer 1

The issue is the line

MS = (MemoryStream);

You seem to be missing something here. Are you trying to cast something to memorystream, if so what?

If you want to construct an MemoryStream obj you need to use something like

MemoryStream memStream = new MemoryStream(100)

Note that MemoryStream implments IDisposable so you probably want to wrap it in a using clause.
