    :thumbsup: 5! I'm always open to correction. Especially when its stuff I'm trying to learn. Think I'll keep looking for a rather more accurate book. :sigh:

      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

        Thanks again for fixing it :-) You don't want newbies who may encounter it in future to go away with wrong info. Good work! :thumbsup:

              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());
                              }
                          }

              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.

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

                            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 disagree. It is lazy, and it shows you don't care about what is being returned. If you explicitly type it then you know exactly what it is and what you can do with it. It's the difference between and ArrayList and a List<T> and I thought that was sorted a long time ago :laugh:

                                Uhm I am confused, there are no anonymous types used in either code snippet! :confused:

                                It's the var keyword, and it's in the first snippet...

                                    Quite a few of them. ;)

                                    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.

                                      Yeah, the number of C# developers who don't understand the var keyword is shocking!

                                        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...

                                        var is used in LINQ extensively so you do not have to create a new class for each LINQ statement that returns a subset of properties from the object being queried(or a new combination from several objects) , e.g.

                                        var result = from employee in employees
                                        select new { employee.Id, employee.Name}

                                        This way you don't have to create a new class containing only Id and Name, but you still get the benefit of strongly-typed LINQ result, i.e. you can do

                                        result.Id

                                        and

                                        result.Name

                                        We can all discuss about benefit of var vs. declaring a variable type explicitly (i.e. var dataReader against SqlDataReader dataReader) till the cows come home and won't go anywhere. I think the benefit of var in this case is very small (if any), and if people don't want to use var for this I'm fine about it.
