Question

Can I convert a IQueryable result to a injected object on the fly?

I know I can do this with the help of Valueinjecter:

usercategory uc1 = new usercategory(example);
usercategoryViewData ucVD1 = new usercategoryViewData();
ucVD1.injectFrom(uc1);

So instead of this:

from u in db.usercategories
where u.id==id
select new usercategoryViewModel {id = u.id, name = u.id, description = u.id};

I would like to use something like:

from u in db.usercategories
where u.id==id
select new usercategoryViewModel.InjectFrom(u);    

The other alternative I have atm is to loop through a IEnumerable and create one with injected objects instead.

Answer 1

here I show 2 ways of doing this:

        public class Foo
        {
            public string Name { get; set; }            
        }

        [Test]
        public void TestMethod1()
        {
            var bars = new[] { new { Name = "aaa" }, new { Name = "bbb" } };
            IEnumerable<Foo> foos = bars.Select(o => new Foo().InjectFrom(o)).Cast<Foo>();

            IEnumerable<Foo> foos2 = from bar in bars
                        select new Foo().InjectFrom(bar) as Foo;

            Assert.AreEqual(bars.First().Name, foos.First().Name);
            Assert.AreEqual(bars.First().Name, foos2.First().Name);
        }
