VB Guru having trouble with "C# boxing"

[Mike Labosh]

Can someone provide a link to something a bit more useful than the MSDN
topics?

Well, what exactly do you want to know? Boxing basically involves
taking a value type value, and creating an instance of a reference type
which effectively wraps that value. It's automatically performed
whenever you need a reference but only have a value - eg:

int i = 10;
object o = i; // Boxing!

Unboxing is the reverse, and requires a cast:

int j = (int) o; // Unboxing!

The type specified in the cast must be exactly right:

long l = (long) o; // Throws an exception at runtime

I don't know if you've tried the MSDN on-line tutorial on boxing. I found it
very helpful.

i thought I knew about boxing, but only got 5 out of 8 for the quiz. The
ones which I got wrong were illuminating.

I always like David Cumps' article on this:
http://weblogs.asp.net/cumpsd/archiv...15/373395.aspx

But it's really not much more complicated than Jon explained in his post :-)
