There is a cool
trick for deleting a item from a database table using the Entity Framework.
Usually you would delete an item like this:
public bool DeleteOrder(int id)
Usually you would delete an item like this:
public bool DeleteOrder(int id)
{
Order order = contextDb.find(id);
contextDb.Remove(order);
contextDb.SaveChanges();
}
However if you want
some improvement, on performance, You could re-write the above code
like this:
like this:
public bool
DeleteOrder(int id)
{
Order orderToNuke = new Order {ID:id};
contextDb.Entry(orderToNuke).State.Deleted;
contextDb.SaveChanges();
}
Entity Framework is
smart to know that that order marked with the Stated.Deleted it needs to be removed from the database.
