Question

i have such code

        var prj = _dataContext.Project.FirstOrDefault(p => p.isPopular == true);
        if (prj != null)
        {
            prj.isPopular = false;
            _dataContext.SaveChanges();
        }


        prj = Details(id);
        prj.isPopular = true;
        _dataContext.SaveChanges();

idea-i have only one record with value true in field isPopular, so i get it and make false, then i get object by id and make it isPopular true. i don’t like 2 calls on savechanges.
any ideas?

Answer 1

var prj = _dataContext.Project.FirstOrDefault(p => p.isPopular == true || p.id ==id);

prj.Single(p => p.isPpopular == true).IsPopular = false;

prj.Single(p => p.isPpopular == id).IsPopular = true;

_dataContext.SaveChanges();
