In a project I am working on, there are really huge collections (1M-1B elements), and things are modified as collections mostly. It's a real-time app, and so the performance is paramount. For some of the operations, like Reverse, BinarySearch (possible?), etc will suffer more than others like Select, etc. Is it feasible to implement o...

I'm just curious... Is it possible to release a variable in c#? What I mean is, can you do something like this: ... string x = "billy bob"; //release variable x somehow string x = "some other string"; //release variable x somehow int x = 329; ... ... so basically you are declaring the variable multiple times in the same scope. ...
How can I use C# on a FIPS-compliant WinXP SP2 box to uniquely hash the contents of a given file? I'm not concerned about performance (yet?). Hopefully someone can point out an exception to the "rule", but it seems that the "*ServiceProvider" classes are FIPS-compliant and unavailable on WinXP, while the "*Managed" classes are availabl...
Using Process.Start, I am starting various IE8 and Firefox (3.5) processes which I keep a Process instance for. A little while later in the application, I'll use the Process instances' MainWindowHandle property to target the window for use with some platform API functions via P/Invoke. However, both IE8 and Firefox will kill the second...
I have to develop a basic "line of business" application with the usual functionality like orders, stock control, sales, reports, etc. I will use WPF to develop this application to run on Windows but I want to develop it "open" so I can do a Windows Forms application using the same structure (maybe to run over Mono) or even a Silverligh...
I have an array of bytes that I would like to store as a string. I can do this as follows: byte[] array = new byte[] { 0x01, 0x02, 0x03, 0x04 }; string s = System.BitConverter.ToString(array); // Result: s = "01-02-03-04" So far so good. Does anyone know how I get this back to an array? There is no overload of BitConverter.GetByte...

Hi! I was just browsing some questions when I stumbled upon this one. I am not experienced in System.Drawing, so I'm just wondering, how would you draw a timestamp onto an image? Also, as I'm very interested in System.Drawing, what are the best resources for learning how to use it well, and its application in various situations? Thank yo...
I have a problem with the VB.NET compiler failing to compile a class (in a separate C# assembly) which contains two overloads of a method with generic arguments. The equivalent code in C# compiles against the same assembly with no errors. Here are the two method signatures: protected void SetValue<T>(T newValue, ref T oldValue) protect...
Hello, What is the best way to resize images using .NET, without losing the EXIF data? I'm okay with using .NET 2 System.Drawing.* classes, WPF classes, or open-source libraries. The only easy way I found to handle this all for now is to use the Graphics.FromImage (.NET 2) to perform the resizing and to re-write the EXIF data with an ...
First, I created a Login page that added a key value pair to the session and verified that on that page the session holds that pair. Next, I attempt to go to another page that looks for that pair in the session and it is not there. I've put the timeout for the session to 15000 so it won't timeout. I currently use a static class to look a...
