How to prevent memory overflow when using an IEnumerable and Linq-To-Sql?

Question

This question is related to a previous question of mine

That\'s my current code

 IEnumerable Get()
 {
     while(//get implementation
           


        

Answer 1

Try using InsertOnSubmit rather than InsertAllOnSubmit. And then commit at appropriate intervals, like Erich said.

Or, if you want to do it in batches of e.g. 5, try Handcraftsman's or dtb's solutions for getting IEnumerable's of IEnumerable. E.g., with dtb's Chunk:

   var actual = Get();
   using (var db = new DataClassesDataContext())
   {
       foreach(var batch in actual.Chunk(5))
       {
         db.Shapes.InsertAllOnSubmit(batch);
         db.SubmitChanges();
       }
   }
