I don't know how many times I've put together the same slow regexp to check if the user input is a valid phone number. I decided that this cannot go on and developed a simple phone number primitive. Now our main concern here is the performance of TryParse since it will be used the most. After running some performance tests the median timing was 400ns on a 3Ghz machine.

Yesterday I made a post about using a queue instead of a list because the code was so much cleaner. I think it is very important that code is clean and easier to read.

But then Denis asked about the performance differences between the 2 methods. I hadn't worried about the performance, because in my case the performance was good in both cases.

But I aim to please my fellow LTDers, so I did a little performance test. And let me remind you that like most performance tests, this one ...

I was doing this in my code.

Are you waiting for .NET 4.0 to take advantage of lazy initialization? Now you don't have to. The question you need to ask yourself is why haven't I already made this myself?

Aren't we all a little lazy?

When you databind your DataGridView to a List.

Like this.

First I create a class Person so I can bind to that. Watch the default constructor, it needs to make new elements, if that is what you want.
