返回多个对象的最佳方法是什么？

Answer 1

为ViewModel创建best practices外观。你的情况 -

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

功能 -

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

创建一个将两个对象包装成一个的类。然后返回你的包装器对象。

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