Question

I am adapting an open source project (NopCommerce). It is a great software and supports extensibility using plugins.
For one plugin, I would like to add information to a view, to do that, I want to inherit from the Controller and override the actions I need to change.
So this is my controller:

public class MyController : OldController{
//stuff

public new ActionResult Product(int productId)
{
 //Somestuff
}

}

I changed the route from my plugin, but when this action get called I get the following error:

The current request for action ‘Product’ on controller type
‘MyController’ is ambiguous between the following action methods:
System.Web.Mvc.ActionResult Product(Int32) on type MyPlugin
System.Web.Mvc.ActionResult Product(Int32) on type OldController

Is there any way I can override this method? (ps: I can’t use the override keyword because it is not marked as virtual, abstract or override in the OldController)

thanks,
Oscar

Answer 1

If OldController’s method is few, Redeclare like this.

public class MyController : Controller 
{
    private OldController old = new OldController();

    // OldController method we want to "override"
    public ActionResult Product(int productid)
    {
        ...
        return View(...);
    }

    // Other OldController method for which we want the "inherited" behavior
    public ActionResult Method1(...)
    {
        return old.Method1(...);
    }
}
