"Set Theory" operations in VB.NET

How can I implement set operations in VB.NET. For example,

{1,2,3,4} union {3,4,5,6} = {1,2,3,4,5,6}

{1,2,3,4} minus {0,3} = {1,2,4}

{1,2,3,4,5,6,7} intersect {0,2,7} = {2,7}

VB.Net doesn't support this natively, but you can build your own classes to
do it. Here's one implementation:

Hello, I have a variable of type unsigned long. It has a number of bits set (with set I mean they equal one). I need to determine those bits and their position and create new numbers from them. For example, consider this four-bit number: 1100 from this number I want to extract two numbers: 1000 and 100 had the four-bit number been 0101 I would want to extract 100 and 1. How should I do this? I wish I had some code to post but I don't...

What class does everyone out there use if they want to store a set of values efficiently? In java I use a HashSet, but there is no equivalent in C#. Even worse, the lowest level interface to define the Add, Contains and Remove methods is an IList, and we all should know that a set isn't a list. ICollection only defines Count and CopyTo, which isn't useful at all. So even if I want to write my own Set implementation, what interface...

Hello! I was looking at marking objects with a changed state, once properties have been changed. The reason behind this is, that I would like to enlist such objects for processing in a transaction. The example below illustrates a sample pattern, which is fine when exposing simple value types. However, when exposing reference types, it becomes really hard (if not

Hello folks, I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>". The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed. This is as boiled down as I can make it. Here is my compilation command: g++-12 -std=c++20 -Wnarrowing bit_field.cpp Here is the code in...

Overview: Windows 11 and 10 have less user interface control over operating system update behaviour than previous versions of Windows. In Windows 11 and 10, there is no way to turn off the Windows Update option using the Control Panel or Settings app; it automatically checks for updates and installs any it finds, whether you like it or not. For most users, this new feature is actually very convenient. If you want to control the update process,...
