Re: ref?

What i don't understand is, in c#, it always uses reference by i thought,
or is it only refs on classes?

Memory is allocated on the stack and the heap; this translates to
primitive "value types" and "reference types." An integer or boolean
is stored by value, whereas instances of classes are created with the
new keyword and then managed by reference, where in your code you have
to variables that are both references to the same object in memory, and
when one makes a change, the other will see it.

Counter-intuitively, though, structs are value types. So if you use "x
= y;" in your code you're cloning the values, not using two pointers to
the same location.
