Question

I have

public class FundController 
{
    private Site _site;
    public ViewResult Fund()
    {
    }
}

I’d like to add an Action Filter to this Fund method:

public class FundController 
{
    private Site _site;

    [MyFilter]
    public ViewResult Fund()
    {
    }
}

but the Action Filter needs access to _site. Is this possible? If so, how?

Answer 1

Expose the field in a public property, then cast the controller in the filter to FundController.

For example:

FundController controller = (FundController)filterContext.Controller;

Site site = controller.Site;
