Creating dictionary with generic types.

Hi ,

I'm trying to use a dictionary in c# as follows
 
Dictionary<Type,IStorage<IEntity>>
and seems to be the declaration and initialization are ok .
Then I create an instance of 
Orderstore:IStorage<Order>
where Orderstore implements the IStorage and Order implements IEntity.
 
But when I try to add Orderstore to the dictionary it says "Argument type Orderstore is not assignable to parameter type IStorage"
I wonder anyone can help me with this. Thanks in advance.

I cannot believe that exception message contains the words "return of the Dictionary", as they make no sense. It may work out if you show the minimal code sample. Show how you initialize key and value object and add a dictionary element to it. —SA

You are right, but better reply to OP's post, not mine. Not a problem though... —SA

Oh, sorry for this abbreviation; it's just the jargon we use on this site, which as not very good, as many don't know it. OP means "Original Poster" or "Original Publisher", something like that, in this case, prasadbuddhika. —SA

Ok, I understand :)

Use the code given below:
 
Dictionary<type,isynchronizedstorage>> myOrders;
 
If myOrders is the name of the dictionary, then use
 
Orderstore order = myOrders[index] as Orderstore;
 
TypeCast it "as OrderSto0re" then your code will work.
 
Regards.
