Question

I had an access to modified closure error in the code below

foreach (var user in Entities.User)
            {
                bool any = Entities.Person.Any(
                    p => p.Name == user.Name);
            }

So I changed it to

foreach (var user in Entities.User)
            {
User theUser = user;
                bool any = Entities.Person.Any(
                    p => p.Name == theUser.Name);
            }

Now, the question is that I want to be able to modify a property of the user object. Does it matter if I do either of the following. Will they both save down to the database when I call SaveChanges on the DbContext?

user.Property = 1;

or

theUser.Property = 1;

Answer 1

Yes. User in this case is most likely a referencec type and thus variables of that type are just references pointing to an instance. The assignment just changes another variable to point to the same instance.
