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.

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();

In Visual Basic:

Dim customersWithoutOrders As IEnumerable(Of Customer) = (From c In db.Customers _ 
    Where c.Orders.Count = 0 _ 
    Select c).ToList()

db.Customers.DeleteAllOnSubmit(customersWithoutOrders)
db.SubmitChanges()
