Insert record in Linq to Sql
- by Anders Svensson
Is this the easiest way to insert a record with Linq to Sql when there's a many-to-many relationship, or is there a better/cleaner way? I wasn't sure why things weren't working at first, but when I added a second SubmitChanges() it worked. Why was this necessary? Would be grateful if someone could clarify this a bit!
private void InsertNew()
{
UserPageDBDataContext context = new UserPageDBDataContext();
User user = new User();
ManyToMany.Model.Page page = new ManyToMany.Model.Page();
user.Name = "Madde Andersson";
page.Url = "anderscom/references";
context.Users.InsertOnSubmit(user);
context.Pages.InsertOnSubmit(page);
context.SubmitChanges();
UserPage userPage = new UserPage();
userPage.UserID = user.UserID;
userPage.PageID = page.PageID;
user.UserPages.Add(userPage);
context.SubmitChanges();
}
