Correct way to perform an update using ADO.Net Entity Model in .net 4
- by sf
Hi,
I just wanted to clarify if this is the appropriate way to perform an update using a designer generated ADO.NET Entity Model.
I was wondering if there was a way to perform an update without creating the sqlMenu object.
public class MenusRepository
{
public void UpdateMenu(Menu menu)
{
// _context is instantiated in constructor
Menu sqlMenu = (from m in _context.Menus where m.MenuId == menu.MenuId select m).FirstOrDefault();
if (sqlMenu == null)
throw new ArgumentException("Can't update a Menu which does not exist");
// associate values here
sqlMenu.Name = menu.Name;
_context.SaveChanges();
}
}
