Hello, Group,
I have been curious about a statement I see occasionally in the VB
(v2003) help. Sometimes the information about a property will indicate
that it is overridable, and I have been making use of this. Sometimes
there is also a statement such as:
"You are not required to override both the get and set methods of the
.... property; you can override only one if needed."
Can anyone tell me how I can override just one of these?
So far, my practice has been to override the "entire" property, and
simply invoke the base property for the piece that I don't need to
adjust. Is there a "better" way?
Cheers,
Randy

why do you need to override only one of them?
any reasons?

Well, that's how I do it too. :-) Well, at least in VB where I believe there
is no other way. It is possible in C# though, so perhaps the note is about
C# and possibly other .NET Framework dev languages?

Hello, Annie,
There are several reasons why I might do this. One example would be to
limit the Set property to a sub-set of possible values. Sometimes I
will throw an exception, effectively making the Set property Read-Only
(or Write-once). Sometimes it's only the behaviour of the Get that I
want to modify.
But invoking the base class property for the "other" half of a Get-Set
combination is pretty easy, so I don't really "need" to do it. It's as
much a question of curiosity as it is wanting to save typing that one
short line.
Cheers,
Randy

Hi, CT,
Thanks for your reply. Yes, I imagine that you're correct, that the
note applies to other languages, but not to VB. (Maybe in the future.)
Cheers,
Randy

Hi
I use the following syntax to have events inherited from base to child classes which works nicely (virtual and override keyword on events). But I am wondering if it is a "supported" way of using events since I never saw it used anywhere in MSDN documentation/samples?! Or it will just break when I upgrade to .NET Framework 2.x in the coming years

public delegate void MyDel()

Hi NG !
I'm new in C# and I'm reading a book about the fundamentals and concepts.
In the chapter Methods it's written to use virtual, if i would like to
override the method in a subclass. This I've to do by using override.
It's also written, that's possible to "hide" the base class method by
using the new key word.
Because I've already written some C# code and I didn't know anything

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.
