[ This article is for Windows Phone 8 developers. If you’re developing for Windows 10, see the latest documentation. ]

Attaches an entity to the DataContext in either a modified or unmodified state.

Namespace:  System.Data.Linq
Assembly:  System.Data.Linq (in System.Data.Linq.dll)

'Declaration
Public Sub Attach ( _
	entity As TEntity, _
	asModified As Boolean _
)

Parameters

entity
Type: TEntity
The entity to be attached.
asModified
Type: System.Boolean
True to attach the entity as modified.

If attaching as modified, the entity must either declare a version member or must not participate in update conflict checking. 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.
