Note, I realize that this has been addressed here.

I posted an answer to this question, including a very short rant at the end about how String.Split() should accept IEnumerable<string> rather than string[]. That got me thinking. What if the base Object class from which everything else inherits provided a default implementation for IEnumerable such that everything now returns an Enume...

What is the easiest way to find out how much memory an object uses in .NET? Preferably without having to resort to a third party tool. Marshal.SizeOf or the sizeof operator look useful but only work with a restricted range of types. Some related posts: Object Memory Analysis in .NET Does an empty array in .NET use any space? ...
Before you start firing at me, I'm NOT looking to do this, but someone in another post said it was possible. How is it possible? I've never heard of inheriting from anything using reflection. But I've seen some strange things... ...
What's a good way for an IE hosted .net user control (e.g., < object classid="myctrl.dll#init">) to pull down an unmanaged dll for it to use? For Click-once, this is easy with a manifest, but ie hosted controls don't get installed in the click-once app cache and instead run out of the download cache. Copy the dll there? Or into the t...
I've got a relatively large .Net system that consists of a number of different applications. Rather than having lots of different app.config files, I would like to share a single configuration file between all the apps. I would also like to have one version when developing on my machine, one version for someone else developing on their ...

I'm looking to implement a function that retrieves a single frame from an input video, so I can use it as a thumbnail. Something along these lines should work: // filename examples: "test.avi", "test.dvr-ms" // position is from 0 to 100 percent (0.0 to 1.0) // returns a bitmap byte[] GetVideoThumbnail(string filename, float position) ...

I've working on a WinForms in VB.NET (3.5) application that requires the user to enter domain administrator credentials. To make things easier on the user, they should only have to enter the user name and password once, and then just rely on my app to save these credentials. I'd like to save these credentials with the other user settings...
I have been thinking about design by contract lately and I was wondering what people think is the best way to assert pre-condition and post-condition of values in .NET? i.e. validating argument values to a method. Some people recommend Debug.Assert while others talk about using an if statement plus throwing an exception. What are the pr...
