He should start off on learning to dance the salsa before moving onto the lambada.

Yes. And I must add that after you get used to using them there are some excellent everyday uses.

seeing it's popular, "Yes!" :laugh:

Errm - they aren't just for C#, and no you don't. You could just continue coding with gotos and monolithic procedures if you really wanted to. After all, who needs these fancy, schmancy features? Productivity is for wimps after all.

Once you get them, they're totally, absolutely awesome. Besides that, it only really takes 10 minutes.

Yes, unless you have something against expressive and easy to follow code...

They're just like nameless methods (from C# 2), but instead of the delegate keyword you have => What's there to learn?

Judah Gabriel Himango

That's not all there is to them. Code-as-data. It's what enables Linq-to-SQL and the million + 1 LINQ providers out there.

Unless, of course, he never used anonymous methods either ....

No, you don't *have* to, but they're extremely useful and I'd highly recommend it. I wrote an article to help out with the learning process: Lambda Expressions and Expression Trees: An Introduction[^] </shameless-plug> Also check out extension methods because a lot of the places where lambdas are used involve extension methods as well. (Whoa, that's cool! :omg: I pasted the link to my article and it automatically put in the link with the article's title! Good work Chris and co! :cool: )

Good call. My most frequent use of lambdas are with extension methods for collections to do things like Where, Select, Sorting, etc.

And unprofessional coders. Never forget the large proportion of progressive and educated development professionals that churn out unprofessional code when they fall prey to these Satanic and Lazy constructs that have only recently been accommodated in the most Utopian language and runtime that is C# 3.0 on .NET Framework 3.5. OK, that felt a bit like little boy scouts probably felt when they held Nazi banners up high for visiting diplomats and politicians.

Brady Kelly

Oh, heathen! What is wrong with redundantly declared (non-)anonymous methods, used in shelf-operations like "Distinct". Oh the code. it haunts me so not having to rewrite an debug it, but I'm not a professional coder, so I must either get used to debugging boilerplate, or shape up and stop rewriting code with spelling and typing mistakes. I mean, I had the logic correct all the time, but these little agents of the Dark One keep throwing magnetic spanners in my freaking production line for "Real Life Output".

Brady Kelly

This whole extension method, new-fangled thang is more dangerous than gay marriage! Vote to stop it before it gets to your youth. :suss: Thatv was a lot easier to squeeze in that a programming post. :laugh:

tonight we will use the lambda, the forbidden construct !

Probably not...but I've been using lambdas in different languages for about a decade now and it is pretty darn handy at times. Right tool for the job and what not.

God No! But if you ever learn it accidentally you will be surprised by how easy and useful it is and you will regret not having learn it before!
