Casting a Type to DBSet

Question

Is it possible to cast a type definition in C#? Such as the following: ``` Type t = typeof(Activity) as typeof(System.Data.Entity.DbSet) ``` Or trying to force a cast: ``` Type t2 = typeof(System.Data.Entity.DbSet) typeof(Activity); ``` I want to create a type definition `System.Data.Entity.DbSet` I'm doing this because I'm using reflection on my domain, trying to pull on the properties on the context, in case anyone asks. ``` // get types we are interested in IHit var instances = from t in Assembly.GetExecutingAssembly().GetTypes() where t.GetInterfaces().Contains(typeof(IHit)) && t.GetConstructor(Type.EmptyTypes) != null select Activator.CreateInstance(t) as IHit; // loop and cast foreach (var instance in instances) { Type t = instance.GetType() Type t2 = typeof(System.Data.Entity.DbSet) as typeof(t); // do something with type 2 } ```

Accepted Answer

I want to create a type definition `System.Data.Entity.DbSet` So you are actually asking `t` to be the type of `System.Data.Entity.DbSet`. Why do you need to cast one type of another? The type `MyDomain.Activity` doesn't have to do anything with the type you are actually requesting. This should work for you: ``` Type t = typeof(System.Data.Entity.DbSet) ``` If you don't have the type of `MyDomain.Activity` yet, you should use `Type.MakeGenericType`: ``` Type dbSetType = typeof(System.Data.Entity.DbSet<>); Type t = dbSetType.MakeGenericType(yourActivityType); ```
