Save ALL Data to Local Storage?

Hi,

I would like an easy way to save all the data for all the entities in one operation. I have looked at the "Disconnected" Tutorial and Level 100 code examples. These examples are based on a simple data graph and the data for the related entities is all pulled together using SPAN queries.

What I am interested in in basically pulling down all the entities regardless of their individual relations to one another. I would like this to be a centralized operation, not running necessarily from a single entity form. I assume this is all do-able and have looked at a possible way to accomplish it.

What I have mocked up is this:

public static void GetAllData ()
        {
            EntityList<ContactMethod> mELContactMethod = new EntityList<ContactMethod>();
            mELContactMethod = MainPm.Manager.GetEntities<ContactMethod>();

            EntityList<ContactMethodType> mELContactMethodType = new EntityList<ContactMethodType>();
            mELContactMethodType = MainPm.Manager.GetEntities<ContactMethodType>();

            EntityList<HBType> mELHBType = new EntityList<HBType>();
            mELHBType = MainPm.Manager.GetEntities<HBType>();

            EntityList<HouseholdBusiness> mELHouseholdBusiness = new EntityList<HouseholdBusiness>();
            mELHouseholdBusiness = MainPm.Manager.GetEntities<HouseholdBusiness>();

            EntityList<Person> mELPerson = new EntityList<Person>();
            mELPerson = MainPm.Manager.GetEntities<Person>();

...<And so on, one for each entity in the system>...

        }

Which I would call right before the "... mPersMgr.SaveEntitySet(path); ..." type code.

Does this seem reasonable? Or do I need to somehow get everything into a single entity graph (like an uber-entity, which linked all the entities together using SPANs)?

Thanks for any thoughts on this.

Pardon my ignorance, but how would I create the "entityTypes" array to pass in?
(I'm new to interfaces, etc)

What I would then like to do is something like this:

IEnumerable<Type> TypeList; foreach (Type t in ~all the objects in my business model~) {     TypeList.Add(t); }

I know the syntax is way off for this, but perhaps you understand what I am getting at?

I noticed that the EntityClass object represents all the different objects in my model:

EntityList<EntityClass> melEC = new EntityList<EntityClass>();             melEC = MainPm.Manager.GetEntities<EntityClass>();                         foreach (EntityClass ec in melEC  )             {                 ~do something with the ec~             }

I tried this:

foreach (EntityClass ec in melEC)             {                 MainPm.Manager.GetEntities(ec.GetType());             }

but ec.GetType() always returns <EntityClass>, of course...

Any ideas?

Thanks, Heather

Thanks, Jeff,

That worked well!

Have a great weekend!
