Question

I have an IList<MyList>. I’d like with LINQ keep the same list (same number of record) but I’d like reduce or/and rename some record. At the end I’d like to have IList<MyNewList>.

Update (Marc Gravell request)
We have tools to generate interface/object from Oracle stored procedure. My problem is, for some stored procedure, a lot of field are created, normal it’s returned by the database (and change the database is not an option). Then the tools generated “Field1,Field2,Field3,Field4,…” but I’d like create a new list with only “Field2,Field4”. this new list will be binded with a GridView.

Answer 1

var newList = (from item in oldList
               select new { item.Field2, item.Field4}).ToList();

or for your own type:

IList<MyNewList> newList = (
       from item in oldList
       select new MyNewList {Field2=item.Field2,Field4=item.Field4}).ToList();
