Type Parameters

  • TSubEntity
    The type of entities to attach.



This method attaches all entities of a collection to a new DataContext. When a new entity is attached, deferred loaders for any child collections (for example, EntitySet collections of entities from associated tables) are initialized. When SubmitChanges is called, members of the child collections are put into an Unmodified state. To update members of a child collection, you must explicitly call Attach and specify that entity.
