Answer 1

I generally try to avoid the Convert class (meaning: I don't use it) because I find it very confusing: the code gives too few hints on what exactly happens here since Convert allows a lot of semantically very different conversions to occur with the same code. This makes it hard to control for the programmer what exactly is happening.

My advice, therefore, is never to use this class. It's not really necessary either (except for binary formatting of a number, because the normal ToString method of number classes doesn't offer an appropriate method to do this).
