'Declaration Public Function Attach ( _ entity As Object _ ) As Object 'Usage Dim instance As DbSet Dim entity As Object Dim returnValue As Object returnValue = instance.Attach(entity)
- Type: System.Object
The entity to attach.
Return ValueType: System.Object
Attach is used to repopulate a context with an entity that is known to already exist in the database. SaveChanges will therefore not attempt to insert an attached entity into the database because it is assumed to already be there. Entities that are already in the context in some other state will have their state set to unchanged. Attach is a no-op if the entity is already in the context in the unchanged state.
