'Declaration
Public Sub AttachAll(Of TSubEntity As TEntity) ( _
	entities As IEnumerable(Of TSubEntity) _
)

Type Parameters

TSubEntity

The type of entities to attach.

Parameters

entities
Type: System.Collections.Generic.IEnumerable(Of TSubEntity)
The collection of entities.

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.
