如何从函数返回具有另一个实体列表作为属性的实体？

Question

How to write a SQL function which would return a class (entity) which has a property which is a List of another class entity using the Entity Framework ?

I have gone through TVF in EF and this is the closest to what I am trying to achieve except that I have a view model wherein there is a List<entity2> .

How do I write a robust function that would return the kind of resultset which will be favourable to the view model?

Some code

    public class Entity1
    {
        public List <Entity2> extra { get; set; }
        public string img { get; set; }
    } 

   public class Entity2
   {
       public string itemType { get; set; }
       public int Quantity { get; set; }

   }

I want to create a view with the view model Entity1 . How can I do this?

Answer 1

You can pass your view model to view like this.First create an object of view model and fill it with data.

DBContext db=new DBContext();
Entity ent=new Entity();
ent.extra=db.Entity2.ToList();//This will get all data from db for entity2 table
ent.img="some value";
return return View(ent);

And in view you will do like this. So you will have data in it

@model Entity

Replace name of DbContext if required.
