Following on from Gary Short‘s message from my previous post on Object Initialisers, I decided to take a screenshot of Orcas displaying the tooltips. I really have to compliment those that designed and wrote intellisense. Not only does it work with object initialisers, but it is intelligent enough to remove properties that have already be …

A start on LINQ
I was at the Microsoft MSDN Roadshow today and I got to see some of the latest technologies being demonstrated for the first time and I’m impressed.

As the type name is not known it needs to be assigned to a variable declared with the local variable type inference, var, keyword. …

This is an ideal that I strive for, however, I have a tendency to write the unit tests afterwards. Some people learn better by example. This article, rather than going …

List<DirectoryInfo> result = new List<DirectoryInfo>(); // Attempt to get a list of immediate child directories from the directory // that …
Passing Values Between Forms in .NET
