Technically the use of "var" in the first example makes it an anonymous type, albeit a simplistic one. Cr@p example though.

Nope. It makes the varible implicity typed i.e. the variable knows nothing about what it will be until the code compiles. A var need not always be neccesarily attached with annonymous types. E.g.
string[] words = { "apple", "strawberry", "grape", "peach", "banana" };
var wordQuery = from word in words
where word[0] == 'g'
select word;Here we already know wordQuery is going to be of type IEnumerable and var need not be used.
IEnumerablewordQuery will work just as well. 1. Apologies for posting code here but I could'nt help it. 2. Thanks for making me do some reading on this. 3. As Nish said, I see what you mean here. But I had to post this, I had to. :) -

That's not fully correct. The variable type is known at compile time. It just saves you some typing :-)

Well actually, the type is resolved at compile time. At runtime, there is no difference between explicit and implicit typing.

The funniest thing about this particular signature is that by the time you realise it doesn't say anything it's too late to stop reading it. My latest tip/trick

I decided it was time I read up on LINQ: never really used it, time I learnt. So, I have a quick look for a book. Amazon: Sams LINQ Unleashed for C#. Lets have a quick look "Surprise me" "check out Wikipedia; Wikipedia is wicked cool at providing detailed facts" Hmmm. Wicked cool? And a code fragment to illustrate how wonderfull anonymous types are:
var request = HttpWebRequest.Create(string.Format(url, stock)); using (var response = request.GetResponse()) { using (var reader = new StreamReader(response.GetResponseStream(), Encoding.ASCII)) { return (reader.ReadToEnd()); } }I hate that. Why use an example where it is actually clearer if you don't use anonymous types?
WebRequest request = HttpWebRequest.Create(string.Format(url, stock)); using (WebResponse response = request.GetResponse()) { using (StreamReader reader = new StreamReader(response.GetResponseStream(), Encoding.ASCII)) { return (reader.ReadToEnd()); } }Don't think I'll buy that one...

It's not the 'wicked cool' that throws me in that statement it the 'detailed facts' Wikipedia is convenient, but not to be relied upon too heavily.

sorry, but type inference makes code clearer, I like the first version better. Why should I have to redeclare the variable's type when
newing it? It's easily inferred from the right-side.var reader = new StreamReader(response.GetResponseStream(), Encoding.ASCII)
is better than
StreamReader reader = new StreamReader(response.GetResponseStream(), Encoding.ASCII)

I agree with you, but it's like arguing about how your favorite color is better than someone else's.
