Question

I’m trying to insert something into a local database, but it doesn’t work..

    ModelContainer mc;
    public DBController()
    {
        mc = new ModelContainer();

    }

    public void SaveArtikel(string name)
    {
        mc.Connection.Open();
        int id = mc.Produkt.ToList().Last().ID + 1;
        mc.Produkt.AddObject(new Produkt() { ID = id, Name = name });
        mc.SaveChanges();
        mc.Connection.Close();
    }

That’s how i tryed it. (It’s mixed with german words..)
After that i have access on the articel but it isn’t in the database..

EDIT:
The db is an .sdf file.

I right clicked on the project and then i pressed on “new item”. There i searched for “Local Database” (Compact Server)

Answer 1

Well, i think it worked all the time..

I published the project to see how it works there. After many tests it looked very good. Even after I restarted the pc the data were in the db.

I don’t know why i can’t see the data manually.. but that’s no problem.

Thanks to all who helped me!
