发帖数: 1072 | 3 Wow, you should get high score in those company promoting columns during the
year-end review! Hope next time I can tell people I just save some bucks by
switching to M$. :)
Right, I won't upgrade it unless the company will reimburse it. Also, for me
.net 2.0 is more like a transition version which is supposed to be replaced
by a more feature-attractive 3.0 version soon(hopefully).

operation is slow; multimedia support is poor; not cross-platforms.

This "why" is interesting. I'm curious.

then gradually get rid of it in v3.0.

发帖数: 1072 | 9 You must be misunderstood what 'var' really means in C# 3.0 as I was when I
first heard about it. It's not the one that we are familiar with in
javascript and there is a strong reason to introduce it into c# 3.0.
'var' is just a shortcut for variable declaration: we don't have to type all
the words for the variable type on the left hand side, the compiler will
INFER the type of the variable from the right hand side. If you look at the
IL, the variable is still strong typed, which means you can't

If so, why not simply declare it as 'Object' instead of 'var'?

发帖数: 1072 | 11 Don't forget 'var' is just a declaration shortcut. The same question would
be 'Why not just declare it as 'Object' instead of 'int/double,...''?
And you can read more about anonymous method in c# 3.0 if interested.

发帖数: 421 | 12 right, one more example, for query expression like
var q = from c in Custs
where c.age > 20
select new {c.name, c.city};
you don't know / want to know the type of q. let the compile do it for you.
