MVC扩展Url.Action方法解决复杂对象参数问题

1:问题描述

　　@Url.Action("Index", "Home", new { Key = "Key", Val = new { Name = "TypeDescriptor" } })

　　 期望结果: /Home/Index?Key=Key&Name=TypeDescriptor

　　 实际结果: /Home/Index?Key=Key

15                     {
16                         GetProperties(dictionary, obj);

18                     if (type.IsValueType || type == typeof(string))
19                     {
20                         if (dictionary.ContainsKey(descriptor.Name))
21                         {
22                             dictionary[descriptor.Name] = obj;
23                         }
24                         else
25                         {
26                             dictionary.Add(descriptor.Name, obj);
27                         }
28                     }
29                 }
30             }
31         }
