Poor var (C#)
-
If you look at this week's poll forum, you can see some pretty nasty comments about the C# var keyword. People seem to have mistaken it to be equivalent to the VB6/COM VARIANT data type. A closer equivalent to the VB6/COM VARIANT would be C# 4.0's dynamic keyword. But to attack var based on some wrong assumptions is sad. Remember, all's fair in love and var ;P

I have a "why var sucks" article in mind. It'll be quite amusing. Marc

I'll want you to explain me what you would use for a linq query that returns an anonymous type, or what is not enough strongly typed for you in the code var records = new List(); For me, var is a blessing. It saves me of repeating redundant information (why the hell would I want to say in the left AND the right hand side that this is a damned List of Records?).

my sentiments exactly. i use var all the time now.

Yeah, this should have been thought of way long ago. Makes one wonder if any other languages have this feature.

Possibly because if you want to find a
Listvariable in a long list of declarations, it's much easier to run your eye down a vertical line of types on the left hand side of the=than to have to scan left and right on each line to find the declaration type.varfor Linq queries I can see the value of,varfor every declaration is confusing.I hope you realise that hamsters are very creative when it comes to revenge. - Elaine

My latest book : C++/CLI in Action / Amazon.com linkI was at a DevDays lecture when 'var' was introduced to the audience. I had a phat laugh at all the self-important 'experts' whose disparaging comments you could hear flying around the audience. The sounded like a bunch of church elders would on hearing one of their members had had his ear pierced.

How about looking for the variable name that should indicate it being a list, or do you declare
List v1 = new List();? I would quickly scan down my list and findvar studentList = new List(); -

I once built a column aligning editor for a COBOL project. Impressed my cute team mate quite a bit, where others were all using notepad and counting columns, ours had tab settings at all the right columns. :)

I think it has big strengths and big weaknesses, if used badly its going to cause confusion, if used correclty it will assist greatly. One rule that I have (and that I love var for) is the variable naming MUST be good else code becomes less readable...

Hmmm... what if object had worked like var to begin with? :suss:
Hmmm, I think I like the way you think... :cool:

This is pure anti-varist propaganda. If there is an enemy in the camp, it is not var. The much-maligned VB party strives not for anarchy, but for freedom with responsibility. The VB party does not condone any acts of violence perpetrated with var or any other tool at our disposal. We do seek to free, but we also strive to educate. Now, we do openly acknowledge that there are those within out ranks who misappropriate the libertarian message of var, who misuse its expressiveness to undermine productivity and pollute the code-base. However, var is not the cause of poor practice, but merely a tool of convenience for the unlearned hack. Take away var and these uneducated code-manglers will find a myriad other techniques to defile your code. They will tangle your classes, force your file handles permanently open, race your threads until they lock, or leach your resources with their crude algorithms and ugle data structures. So, we recognise that there are those who misuse the tools we provide, but argue that this is true of every party, regardless of colour and flag. And may I say this to those who besmirch the good name of the VB party: you speak of the impurity promoted by var, but ignore a greater danger: providing unregulated access to the world of unmanaged code, a realm where the uninitiated are free to dangle their pointers without reprise nor censure! He who is without sin, my friends, he who is without sin.

I remember Sun insisting at conferences several years ago that the
unsafekeyword in C# would be its downfall. People are idiots.unsafewas named so 'scary' and buried under an extra compiler option that nearly no one is using it. I've seen code doing manual marshaling (Marshal.AllocHGlobal,Marshal.Copy, etc.) for P/Invoke calls which could have been replaced with a simplefixedblock around the P/Invoke call.
