Question

I have a class:

public class Data {

 public Ilist<Prod> Product;

 public Data() {}
  public Data(List<Prod> prod)
  {
      this.Product = prod
  }
}

No I try to use this class in my controller to bind values to my model

public ActionResult Index(string username)
  {
     data.Prod =  GetProductByUser(username); // this is the base user

     IList<AdditionalUsers> add_usrs = GetAddUsersForBaseUsers(username);

     // now to the data.prod (product list I need to add the prod for the base users
     //so I loop through the add users and try to get the products for each base use

     for(AdditionalUsers aid in add_usrs)
     {
            //now data.prod has products for base users. So now I need to add produts 
            //for add users using same method

     } 

}

Now in the for loop I need to call the same method GetAddUsersForBaseUsers(username); to add product for all the additional users and add it to the data.Product list. How will I be able to do this?

Answer 1

Ok, your constructor is wrong. You’re trying to set data.Prop where Prop is a type, not a public field/property.
Also, where are you declaring your data variable?

You could use the following instead:
Data data = new Data(GetProductByUser(username));

Make your Product field as a publicly accessible property as well.
To do this, replace
public Ilist<Prod> Product;
with public IList<Prod> Product { get; set;}

To Add the users, you can use the following.

foreach(AdditionalUsers aid in add_usrs)
{
   //add users
   data.Product.Add(aid);
} 

Alternatively you can just replace the property Product which is of type IList with a List and then do the following:
data.Product.AddRange(add_usrs);
