How to define constrains for multiple different generic types

I have following interfaces defined

interface IStoreItem
{

}

interface ILoadItem
{

}

Now I would like to implement a collection which can handle items of these interafeces but usually a class which realises IStoreItem will not realise ILoadItem. So is there some way I can define a constrain like this:

p开发者_开发问答ublic class NetworkingCollection<T> : List<T>
   where T : IStoreItem or ILoadItem
{

}

This is not supported.

You will need a different class for each interface you want to constrain to.

Alternatively, if you inherit IStoreItem and ILoadItem from a common interface (say IGenericItem), you could constrain to the parent interface.
