      Ah, I wondered what happened to the generics bit on my OP How is it sloppy and lazy?

        You know what the variable type is, so declare it!

          Why? What is the point of repeating information?

            I agree, I've seen code here with var used everywhere (C#), complained to the SW Architect, he sent out an email saying it sould only be used where required. It's the newest, youngest guy in the place using it most. It's F***in sloppy, lazy sh*t!

              Coming from a C++ background, I feel it doesn't improve the readability of the code, particularly when used to accept a return value from a method. In my experience, those that like it overuse and abuse it. It was a mistake to add it to the C# language.

                I come from a C++ background too and I like var - I agree using it to accept a return value from a method is a poor use of it.

                  And why? I can understand some cases in which you want to make code more compact, as

                  List myName = new List();

                  to use a

                  var myName = new List();

                  or as mentioned before in cases that you do not know the return type. But using always var only because of laziness, just pisses me of!

                  The 'why' is because the type is already there in the line, so using var doesn't remove any information. Personally I only use it very rarely but that's a matter of style, I think it is fine when the type is in the line anyway (either as a new expression or an explicit cast: var something = (TypeName)expression).

                    I'm so pissed of by var abusers. They do not understand that are making code unreadable, for what, writing var instead of string? Having the same problems in your company? ex.

                    var metadataValues = new List<object>();
                    foreach (var metadataDefName in metadataDefNames)
                    {
                    var name = metadataDefName;
                    // Search definition with the same name.
                    var metadata = metadataCollection.FirstOrDefault(
                    metadataDef => String.Equals(metadataDef.MetaData.Name, name, StringComparison.OrdinalIgnoreCase));
                    ...

                    Cheers!

                    Reason for my 1 vote: There is nothing wrong with that. If you need to get the type, just hover over the 'var' in the IDE.

                    ((λ (x) `(,x ',x)) '(λ (x) `(,x ',x)))

                      Meanwhile I'm reading the code I can't constantly hover the vars! Com'on, how can you say that??? :) And this is the lounge, I'm not discussing about what should be a good practice, I lament about things that makes me piss off.

                        Or you are using ReSharper and tell it to autofix the "problems" in your code.

                        Well put. Exactly why I do NOT use handholding tools like Reshaper. Clearly their definition of 'problems' is very subjective, and personally does not suite me. I write the code exactly how I want it!

                          Use Reflector then :) If the code is well written, you should be able to infer the type while reading. What does get me is the person using 'var' instead of 'object', now that is silly. :)

                            C++ has it too now, it's called auto.

                            auto x = SomeFunc();

                              Many people don't know what C#'s var means. They incorrectly think it's not type-safe! :-)

                                  I haven't looked at it enough to concern myself with whether or not it's type safe. I don't think it aids code readability, and I've never found a situation where I needed to use it.

                                    It's nice to be able to read the code without hovering the mouse over things. And one might not be in an IDE at the time.

                                      I can't hover over it when it's printed on a page, posted in a message here, displayed by someone else on a big screen in a meeting, etc.

                                        GAH! I don't need to see that when I first wake up in the morning! What were you thinking, man? Post it later in the day. :~ But I certainly agree with you.
