ASP.NET MVC 2：返回多个对象？

Question

List<Filter> filters;
List<Deal> deals;
using (DealDataContext db = new DealDataContext())
{
    XElement xmlTree = XElement.Parse("<Request><ZipCode>92618</ZipCode></Request>");
    var result = db.SearchDeals(xmlTree);

    filters = result.GetResult<Filter>().ToList();
    deals = result.GetResult<Deal>().ToList();

}

return filters, deals;

What is the best way of returning more than one object?

Answer 1

Create a ViewModel look for best practices . Your case -

public class DealViewModel
{
List<Filter> filters{get; set;}
List<Deal> deals{get; set;}
}

Function -

DealViewModel vm= new DeakViewModel();

using (DealDataContext db = new DealDataContext())
{
    XElement xmlTree = XElement.Parse("<Request><ZipCode>92618</ZipCode></Request>");
    var result = db.SearchDeals(xmlTree);

    vm.filters = result.GetResult<Filter>().ToList();
    vm.deals = result.GetResult<Deal>().ToList();
    return vm;

}

Answer 2

Create a class that wraps both objects up into one. Then return your wrapper object.

public class Wrapper
{
   List<Filter> Filters { get; set; }
   List<Deal> Deals { get; set; }
}
