I've been a long time reader of the site, and I've been thinking about posting my first article soon. In short, I've been writing a library for basic linear algebra operations. Essentially, I've thrown in most of the applications that you'd see in a good introductory college linear algebra course (guess which class I'd just taken when I started this). Anyways, I was just wondering if anyone here had any particular suggestions to share with a first time submitter.

It really depends on what you want to do. For web programming, PHP, ruby, or asp.net would probably be good choices. For desktop programming, C++ would definitely be the way to go, although java might also work well for you. Also, at some point I'd really recommend spending some time with C and assembly. They aren't necessarily the best introductory languages (although the first programming class I ever took started from assembly and then went to C), but a good grasp of the low level workings of the computer will help you out.

Ok, I see what you're saying now. Thank you very much for your help.

First off, thank you very much for the help so far. I am a little unclear on what exactly you mean here. Could you please be more specific what property I need to implement to make this work with a foreach statement? I've been looking and can't seem to find any documentation on it. Everything I've seen seems to assume that you only want to iterate for one data type. Is what I'm trying to do even possible?

I think so. Do you know of an example anywhere that you could point me to? Right now, I have something like: IndexType IEnumerator.Current{...} KeyValuePair IEnumerator>.Current{...} and I am getting the error Error 1 foreach statement cannot operate on variables of type 'Myclass' because it implements multiple instantiations of 'System.Collections.Generic.IEnumerable', try casting to a specific interface instantiation 232 The foreach statement is foreach (int i in info) where info is of type Myclass

Hi everyone, I've been writing a class that I want to be able to enumerate over different types in a foreach statement. I've tried googling with no luck, and I was hoping that someone here could help me out.
