I am trying to create a quick hashcode function for a complex number class (a + bi) in C#. I have seen repeatedly the a.GetHashcode()^b.GetHashCode() method. But this will give the same hashcode for (a,b) and (b,a). Are there any standard algorithm to do this and are there any functions in the .Net framework to help? ...
While making some final tests of a class-library that I'm writing for Windows Mobile (using Compact Net Framework 2.0), I ran into an OOM-exception. Basically, my library loads first a dictionary-file (an ordinary text file with a word list) and thereafter another file based upon the dictionary (I call it KeyMap) which size is more or ...

What is the purpose of the 64 bit public key token in .NET Assembly. I understand that the public key corresponding to the private key which is used to sign the assembly is embedded in the assembly itself.

Does anybody know of or have a detailed list of how the BCL in .NET 4.0 has changed from 3.0? In other words, what types have been added or deprecated (or how have they changed)? All I have been able to find is the list of new features, such as the Wikipedia article, any of the endless MSDN blogs entries about it, or some questions her...

I'm using SerializableAttribute to write an object jack to disk. The object has a member department which references a static field accounts of another class Department.

Is there a switch to suppress specific compiler warnings when using the aspnet_compiler.exe warnings at the command line? I've tried fixing the errors myself, rather than ignoring them - they are for events that are defined by never used. I simply commented out the events, but this caused other problems! It's as if they are used but the...

I would like an elegant way to capture a thread end/exit event. I've found two approaches so far: Use background worker, which has a RunWorkerCompleted event, or, Have my thread worker explicitly call an "I'm Exiting" delegate. Yes, these will work, but there must be some way from the parent thread (the thread that calls the Thread.S...
I have a class with lots of string properties that need validated. I'm using the Validation Application Block because I'm a big fan of using attributes to solve this kind of need.

I have a certificate installed that has a private key, exportable, and I want to programmatically export it with the public key ONLY. In other words, I want a result equivalent to selecting "Do not export the private key" when exporting through certmgr and e...
