Casting generic type “as T” whilst enforcing the type of T

Question

I\'m missing a trick here I think and can\'t believe I\'ve never done this before. However, how can I cast a generic type using the as keyword?

[Serializable]
pu         


        

Answer 1

... where T : class, ISessionManager

In case you want to use the where keyword on methods here is an example that also uses generics

    public void store(T value, String key)
    {
        Session[key] = value;
    }

    public T retrieve(String key) where T:class
    {
        return  Session[key] as T ;
    }
