  • Blog Post: Iterator Usage

    OK, a few days ago I asked about how you used anonymous methods . Thanks for the very few who responded. I'm hoping that more people have used them than chose to respond. Now it's time to ask about my other pet feature: Iterators. How an possibly more importantly why do you use iterators? I'm sure that...
  • Blog Post: More thoughts on Iterators

    So I had a short email exchange with a collegue about iterators. He mentioned that I should put in in my blog. Seemed reasonable, so here it is: Subject: Iterator generated code ... I'm looking at porting a hand-coded enumerator to use iterators (this is for a sample and maybe an...
  • Blog Post: Remoting...

    First off, I don't even pretend to have a good comprehension of how remoting works. What I do know is that right now the compiler generated classes derive directly from Object, and somehow this is bad for remoting, instead they should derive from MarshalByReferenceObject. On the surface that is a...
  • Blog Post: Recursive Iterators made Iterative

    So I've been thinking about this, and although it seems like CS101 to transform a recursive algorithm into an iterative one, and example might be worth while. The natural one to attack would be the generic binary tree traversal iterator. So here goes! My first thought would be to use the new Queue...
  • Blog Post: A good author writes better than a good developer

    So here's a recent MSDN article that I actually had the chance of reviewing several months ago. They've done a much better job at capturing the good new stuff in C# than I could ever do. http://msdn.microsoft.com/vcsharp/default.aspx?pull=/msdnmag/issues/04/05/c20/default.aspx I do still have a...
  • Blog Post: Some Cool New Features

    I've been looking over some of my last few posts and they could easily come across as if I thought iterators and anonymous methods were the worst language features every added, and will never serve a good purpose. If anything I think the opposite (or else I wouldn't have spent so much time on them)....
  • Blog Post: Recursive Iterators (aka Perf killers)

    Technically this isn't specific to iterators, but its so much easier to do with iterators that I thought I'd mention it. Some languages are smart enough to 'flatten' iterators, such that if an iterator is called insde of another iterator, only one iteration object exists. C# is not one of those languages...
  • Blog Post: Anonymous method (and Iterator) perf

    probably a few of you hav asked how to make iterators and anonymous methods fast. Well hopefully if you understand how the compiler translates them, it should be relatively easy to optimize them. The first thing to remember is that for all practical purposes the C# compiler does not have an optimizer...
