Question

I would like to pass certain data from an instance of an object to its attribute, and I have troubles inderstanding how to implement it. Here’s a sample:

[AuthenticateAttribute]
public class MyController: Controller
{
    UserInfo info;
}

The idea is that AuthenticateAttribute instance would populate the UserInfo instance.

I want to pass reference to info to an instance of AuthenticateAttribute and thereby eliminate strong coupling between the attribute and the particular MyController class.

Is this possible?

Answer 1

The attribute itself shouldn’t have the UserInfo field IMO. Bear in mind that there will be one instance of the attribute for the type it’s applied to – not one per instance of that type.

If you could give a fuller example (showing the code it’s applied to) we may be able to help more…
