How do you insert an IEnumerable into entity model collection?

Question

I have an IEnumerable and I want to insert all the items into an Entity Model collection. e.g. Looking for a way to do the following:

var missingitems = IEnumerable<MissingItem>();
//Add lots of Missing Items
modelContext.MissingItems.AddList(missingitems);

Instead of having to do:

missingitems.ToList().ForEach(mi=>modelContext.MissingItems.Add(mi));

Check [Add range to ICollection](http://stackoverflow.com/questions/1667614/t-in-class-addrange-icollection/1667634#1667634) answer — Eranga, Aug 21 '11 at 09:18

There is no AddList or AddRange. You can create your own extension method which will offer you your expected syntax but internally your new method will still call AddObject (or Add in DbContext) in loop because AddObject (Add) is not just adding to "collection".

Maybe something like:

var missingitems = IEnumerable<MissingItem>();
//Add lots of Missing Items  
modelContext.MissingItems.AddList(missingitems.ToList());

I don't have AddList as an option under intellisense? Just AddObject ? – BlueChippy Aug 21 '11 at 09:13
