Anonymous Methods and Types

[Chris Losinger]

i think they're great for things like simple sorting predicates. other than that... i dunno.

Yeah, I know - the first versions of MFC drove me to the hands of Delphi in the beginning of my career.

Yeah, I used to love it when people complimented my physic. But that's in the past. :( A lumbar spinal disc prolapse ruined the whole thing for me more than 3+ years ago. Now that I've recovered, I'm back at the gym (about 2 months now) and am trying to gain muscles. And am having to take special care not to put load on the spine or on the lower back. No noticeable improvements so far, and I'm not able to take even one fourth of the weights I used to train with. I know that's natural, but it's all depressing as this is a fascination for me. I won't give up, but it's going to take a while. :|

Especially considering the fact that the Sun banned the delegates from Java just to be contrary to Microsoft. As a direct result the event handling in Java Swing is a little clumsy/compared to .Net, Delphi or even MFC/.

Hope you will get back in shape shortly.

I disagree, just because it's possible that anonymous methods are messy, it doesn't follow that they are:

delegate void Foo(string s);

static void WriteToConsole(string j)
{
System.Console.WriteLine(j);
}

public static void RunSnippet()
{
Foo bar = WriteToConsole;
bar("The delegate using the named method is called.");
}

is far less terse than:

delegate void Foo(string s);

public static void RunSnippet()
{
Foo bar = j => System.Console.WriteLine(j);
bar("The delegate using the named method is called.");
}

Once you get used to reading the syntax, sometimes it is just much cleaner to do it this way. If you need to doe something more complicated, then the anonymous method will look messier but, often, the anonymous method should be an actual method on the object type that is being acted on. Ironically, this means the "closure" stuff is cleaner if you get the object encapsulation right.

In other words, a closure.

How can an anonymous type be a closure? :~

With few exceptions, clear, simple code optimizes much better than convoluted "fancy" code. C# is no different.

On the other hand, if it's such a problem to you, maybe you're in the wrong business?

How about doing some proper exercise :-)[^] Seriously though, do a summer's worth (i.e. a few training expeditions and then the main thing) and you'll see how quickly you become fit lugging a 50lbs rucksack around the mountains. You're expected to (as a 16 yro kid) eat a minimum of 3,500-4,500 calories per day just to keep going (you'll probably lose a bit of wait even with eating that much, I did).

Thanks, I could try that some time. :)

Only one place I use var

var has very little to to with anonymous types[^]. In your example, it just declares a reference to the actual anonymous type.

Just look for FP (or functional programming) themes/books/articles/hypes/whatever ... and you will see that those are THE BEST feature we got in the last couple of years - I combination with closure caps and generics you can finally say that FP made it mainstream (and with F#, Clojure, etc. you can see that many people are very happy about this). I'm using anon. methods almost everywhere (who said "if you have a hammer every problem looks like a nail!"?) I hide variables in closures, I use those for "lazy"-support etc. pp Greetings, Carsten

I use them as a shorthand return object from web service calls from script (they get serialized into JSON anyway).

Here is a Professor's take on it: - Generally we want to create re-usable types, perfect their interfaces, implementation of interfaces and ensure they are robust. Obviously anonymous types can not be used here. - However, quite often we have a need for a type that is very specific to the task at hand and will not be reused. Anonymous types can be used here and do allow better readability in that the code (delegate or type definition) is where the use of it is. Of course I tell my class that these were really required for LINQ.
