Question : LINQ to SQL insertonsubmit, multiple instances before submitchanges

My code constructed as below writes only 1 record to the database. What am I doing wrong?

AllItemData is an object, the members of which are two lists. This code only refers to the first list. There are 6000+ items in the list, and the code does iterate through all 6000+.

Answer : LINQ to SQL insertonsubmit, multiple instances before submitchanges

no, just the itemTable line. You wouldn't want to create a new DataContext for each record. You only need one instance of the DataContext.
