ASP.NET MVC & Entity Framework: How to render a custom Model in a View?
I have two tables Category 1..* Advertisement.
I want to get the advertisements Count for each category. To do so, I use that开发者_开发知识库 query:
var catList = (from c in DB.Category.Include("Advertisement")
select new { c.Name, c.Advertisement.Count }
).ToList();
How to access the e.g the first element's property Name and Count via View ?
I'd use a view model, like:
var catList = (from c in DB.Category.Include("Advertisement")
select new CategorySummaryViewModel{ Name = c.Name, AdsCount = c.Advertisement.Count }
).ToList();
Unrelated & not sure: but I think you can take out the .Include in that linq query / since you are getting a projection, not a Category instance that you want it's Advertisement property populated.
You will have to use a collection of a strongly typed object instead of using anonymous types.
Please see Dynamic typed ViewPage for an explanation, but the readers' digest version is that anonymous types are internal.
