Puts all entities from the collection into a pending delete state.
Assembly: System.Data.Linq (in System.Data.Linq.dll)
Entities that are put into the pending delete state with this method do not disappear from query results until after SubmitChanges is called. Disconnected entities must be attached before they can be deleted. For more information, see Data Retrieval and CUD Operations in N-Tier Applications (LINQ to SQL).
The following C# snippet shows one use for this method:
IEnumerable<Customer> customersWithoutOrders = (from c in db.Customers where c.Orders.Count == 0 select c).ToList(); db.Customers.DeleteAllOnSubmit(customersWithoutOrders); db.SubmitChanges();
