Re: Passing arguements by reference

I understood everything upto the code above, You say its passed by

that is by value then? :-/

The subtle point to note is that the underlying object is passed by
reference, hence both p and q pointing to the same object, not to different
object BUT the actual variable which points to the object is copied when you
don't use the ref keyword.

Passing a reference by value *isn't* passing an object by reference.
It's similar, I admit - but there are very specific meanings for the
teams, and they're not the same thing.

(This is compounded by the fact that no expression is actually an
object in C#.)
