Question

I’m new to EF. I have some code that successfully inserts a record in a table. However, it uses the autogenerated “addto…” method which I understand is depreciated. I’ve seen references to using the “add” method but am having trouble. Here is the code that works:

    Dim EntityContext As New DevEntities
    Dim log2 As New tblLog2

    log2.Error = "This is a test."
    log2.Date = System.DateTime.Now
    EntityContext.AddTotblLog2(log2)
    EntityContext.SaveChanges()

What is the “correct” way to insert this record (vb please)?

Answer 1

Yes, you need to use ObjectSet<TEntity>.AddObject Method:

    ...
    EntityContext.tblLog2s.AddObject(log2)
    EntityContext.SaveChanges()

Basically ObjectSet.AddObject is a wrapper around the ObjectContext.AddObject method so the above call is equivalent to :

EntityContext.AddObject("tblLog2s", log2)    

Note: I assume that tblLog2s is the EntitySet name oftblLog2 entity.
