Playing with code

[andrewducker]

God, I wish we had the latest version of Visual Studio at work.

I spent the morning playing with C# code after reading this article on brevity in code.

Trying to find something that I preferred over the Ruby code that did this:

“”.methods.sort.grep /index/i

and eventuall ending up with:

from methodName in "".MethodNames() 
  where methodName.Grep("index",RegexOptions.IgnoreCase) 
  orderby methodName select methodName;

The main thing that would be nice would be a simple sort keyword that could be used if only one variable was being operated on, and likewise not needing a select if there's only one item being dealt with.

Can you use lambda syntax to do that and skip the select?

"".MethodNames().Where(m => m.Grep("index", RegexOptions.IgnoreCase)).OrderBy(m => m);

Of course, yes. Go so wound up in playing with LINQ I didn't think to go for a straightforward method of object calls.

Shame, of course, about that last step being necessary. Of course, for a simple text sort I could create another extension method.

Haha. Yes.

whe you get what you are happy with then wrap it in a method in some common library and it's as neat as you like :-).

maybe I miss the point :-)

But when every thing you do is different, but they all take lots of hard to read code, it's tricky.

I have to agree that the Java example he gave is ridiculous for "get a list of methods, sort them and filter them". I'm glad C# makes it a lot easier.
