I have a situation where I have to combine an enumerated value with an
interface. How can this be done?
namespace Stuff
{
public interface IThing
{
// This doesn't work, of course...
public enum EnumeratedStuff
{
None, First, Second
}
bool SomeMethod();
}
}
namespace Stuff
{
public class Thing : IThing
{
// Implement the enumerated EnumeratedStuff .
bool SomeMethod()
{
return true;
}
}
}

Do you mean something like this:
namespace Stuff
{
public interface IThing
{
bool SomeMethod();
EnumeratedStuff EnumStuff{ get;set; }
}
public enum EnumeratedStuff
{
None, First, Second
}
}
namespace Stuff
{
public class Thing : IThing
{
private EnumeratedStuff es = EnumeratedStuff .None;
public bool SomeMethod()
{
return true;
}
public EnumeratedStuff EnumStuff
{
get { return this.es; }
set { this.es = value; }
}
}
}

Richard,
You can't do that. The enumeration has to be defined outside of the
interface, and you can't declare that the interface has to declare an
enumeration type with that name.

I am trying to enumerate the elements of a Compound storage file and I get an error (System.NullReferenceException) when I execute the "EnumElements" of the "UCOMIStorage". I can open the Compound file just fine just can't enumerate it's elements. Am I declaring something incorrectly?

Sure... IEnumerable was inconvenient suggesting a separate class to service
the enumeration, IEnumerator, and multiple operations: Current, MoveNext,
Reset. (I'll warp the definition of "operation" for a second if you don't
mind).
However, it existed within intuitive language semantics, whereas the new
"yield" keyword, while highly convenient, is also one of the most gross
warping of language concepts to date...

Is there a simple way to return a COM enumeration interface from .NET? I am
porting a C++ COM Object that has an enumeration interface containing the
DISPID_NEWENUM and DISPID_VALUE properties and the count property and need
to create the equivilant in C#. I'm hoping I can just return an array list
or something but something tells me it isn't that easy. Any thoughts on the
proper way to do this in C#? Thanks.

The problem:
We have an interface (EnumInterface), an enumeration container
(EnumContainer) and an enumeration type (TheEnum). We can set the
EnumContainer through the EnumInterface. However when we retrieve the
EnumContainer from the EnumInterface, the TheEnum within the EnumContainer is
null (Assert.IsNotNull(enumService.getEnumContainer().anEnum); throws an
exception).
Any reason why C# can't retrieve the enum value ?

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.

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,...
