Custom Promotions and finding their custom type


Ihave two custom promotions setup which apply two seperate Episerver abstract classes; both of which I have also inheriting from an interface:

    public class PromoA: BuyQuantityGetOrderDiscount, ICustomPromo

    public class PromoB: BuyQuantityGetSelectedItemsDiscount, ICustomPromo

When I get to the point of checkout I get the generic PromotionData back but it doesn't tell me what custom promotion it is.

Does anyone know of a way to get this information.

Ie I need to know if the PromotionData is based on Promo A or Promo B.

Otherwise I have to go down the route of trying to cast the PromotionData to either of these type - and that will get very messy.

Could you load the PromotionData up and then check the FullName of the type? Something like:

var appliedPromotion = ContentLoader.Get<PromotionData>(PromotionGuid)
var promotionFullName = appliedPromotion.GetType().FullName

if(FullName.Contains("PromoA")) doSomething()
if(FullName.Contains("PromoB")) doSomethingElse()

Investigating this option - thanks for the suggestion :)

Can't you just check

if (promoA is BuyQuantityGetOrderDiscount) 



else if (promoA is BuyQuantityGetSelectedItemsDiscount)

I didn't want to do it this way because it we would have to have if statements for all our Custom promotions which felt messy.

well, it's up to you, but you have compile time type check, and clear intention of what you are trying to do.
