I'm new to C#, so just point me at the correct reference material if this
question has been answered before.
When creating a new class which implements the IDictionary interface, two
versions of the GetEnumerator method must be defined (one from the
IDictionary interface, one from the IEnumerable interface).
The first is defined as:
public IDictionaryEnumerator GetEnumerator()

Hello all;
Since I do have working code, this is more for my curiosity only.
I'm creating a "Plugin" architecture, following some of the many examples on
the 'net. Basically what I have is this:
- a DLL which contains the interface that every plugin must implement
(IPlugin). This DLL also contains a class with the ability to search for
DLLs in the calling applications working directory that contain classes
implementing IPlugin (I...

I've constructed a class that inherits the NameObjectCollectionBase
class. All works well, but I'd like to shadow the GetEnumerator method
so that it returns an actual value *instead of a DictionaryEntry*.
I've gotten strange errors when attempting to override GetEnumerator,
such as 'GetEnumerator() cannot override 'Public Overridable
NotOverridable Function GetEnumerator() because it is declared
NotOverridable......yes, it actually...

Hi,
I feel I'm going around circles on this one and would appreciate some other
points of view.
From a design / encapsulation point of view, what's the best practise for
returning a private List<as a property.
Consider the example below, the class "ListTest" contains a private "List<>"
called "strings" - it also provides a public method to add to that list,

I'm trying to compile myGeneration PropertyCollectionAll.cs file with VCS
Express 2005 bot got error
Error 1 The type or namespace name 'Collection' could not be found (are you
missing a using directive or an assembly reference?)
PropertyCollectionAll.cs 17 39
I looked to .NET 2 help and found that Collection class is included in
mscorlib so it doen't need assembly reference.
How to fix this error ?

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,...
