Question

When I enter an object into the DB with Linq-to-SQL can I get the id that I just inserted without making another db call? I am assuming this is pretty easy, I just don’t know how.

Answer 1

After you commit your object into the db the object receives a value in its ID field.

So:

myObject.Field1 = 'value';  // Db is the datacontext db.MyObjects.InsertOnSubmit(myObject); db.SubmitChanges();  // You can retrieve the id from the object int id = myObject.ID;
