Set a class attribute result with a custom attribute

Hi, I'm trying to create a custom attribute that applies to class attributes of type string and ensures that when you read the value of this class attribute, it always returns a specific string. Is this somehow feasible?

You want to apply an attribute to other attributes of the method your attribute is attached to?

I mean like this:
[MyCustomAttribute]
public string ClassAttribute { get; }

Suiram1OP•3/4/23, 2:56 PM

And MyCustomAttribute should ensure that the ClassAttribute returns a specific value

You can't really "ensure" that

Suiram1OP•3/4/23, 2:57 PM

But is it possible to do that?

Thinker•3/4/23, 2:58 PM

Can you elaborate further on how you want this to work? Like should the attribute limit the values of the property or what?

Thinker•3/4/23, 2:58 PM

Also is a property, not an attribute

Suiram1OP•3/4/23, 3:03 PM

Yes, I mean a property and I would like that if you read the property, i.e. , that a value that is stored in the attribute is returned

Thinker•3/4/23, 3:03 PM

so like the attribute 'overrides' the property?

Suiram1OP•3/4/23, 3:04 PM

Yes

Thinker•3/4/23, 3:04 PM

unfortunately you can't do that

Thinker•3/4/23, 3:04 PM

attributes are merely metadata, they don't affect behavior or execution in any way

SSuiram1 I mean like this: [MyCustomAttribute] public string ClassAttribute { get; }

ero•3/4/23, 3:04 PM

Ok so we call those properties

ero•3/4/23, 3:05 PM

Because "attributes" already have a very specific definition in c#

ero•3/4/23, 3:06 PM

Thinker already said that whoops

Thinker•3/4/23, 3:06 PM

yeah

Suiram1OP•3/4/23, 3:09 PM

Ok, thanks I just thought it could be done because I saw something like that in other c# code where I thought it would do this

Thinker•3/4/23, 3:09 PM

where?

Suiram1OP•3/4/23, 3:18 PM

Oh sorry, settled it wasn't what it looked like
