I ended up with something like the following code in a project I'm working on. I thought it was really odd that I was allowed to do it, but now I'm starting wonder what is most likely an architectural gaff on my part led me to this. My questions to you are: What exactly is this called? What are some real world uses of this? Why would...
I have a C# Excel Add-in project "MyExcelAddIn" that has a public method Foo() to do something complex. For testing purposes, the add-in also defines a toolbar button which is wired to Foo() so I can test this and verify that clicking the button calls Foo() and does what I want it to do. This is fine. Now I want to call this method from...
I was reading another answer. And it made me wonder, when do does one need to explicitly call Dispose if I am using using statements?

The following function does the job, but a shorter and sweeter version (LINQ?) would be nice: Dictionary<int, string[]> MergeArrays( IEnumerable<int> idCollection, ...
Hi, I got a NullReference problem using WWF and externaly raised events. The WWF state machine works together with a service instance raising events in the state machine to provide data and - of course - to change the state. While the "normal" operation works fine using events I got a strange problem. To handle timeout scenarios I let...
I'm looking for an easy way to find the process tree (as shown by tools like Process Explorer), in C# or other .Net language. It would also be useful to find the command-line arguments of another process (the StartInfo on System.Diagnostics.Process seems invalid for process other than the current process). I think these things can only ...

So I am making a piece of software in WPF, and I want to be able to make graphs out of the data I am storing. Just line graphs with x and y axises. Ideally I would want them to have a nice elegant simplicity to them. I know WPF doesn't come with graphs, and I have tried ZedGraph in a WinForms project, but I thought frankly it looked...

This meant I had to get the latest trunk of S#arp. Also, two weeks ago, I updated from XP to Vista (32 bit) My problem is that the performance has suddenly become woeful...
