Valueinjecter映射复杂对象

Question

我有这个简单的代码：

using Omu.ValueInjecter;

namespace InjectionTest
{
    public class Partner
    {
        public int Id { get; set; }
        public string Name { get; set; }
        public City City { get; set; }
    }

    public class City
    {
        public int Id { get; set; }
        public string Name { get; set; }
    }

    public class PartnerViewModel
    {
        public int Id { get; set; }
        public string Name { get; set; }
        public string CityName { get; set; }
    }

    class Program
    {
        static void Main(string[] args)
        {
            var city = new City()
            {
                Id = 1,
                Name = "Athens"
            };

            var partner = new Partner()
            {
                Id = 1,
                Name = "Acme d.o.o.",
                City = city
            };

            var vm = new PartnerViewModel();

            vm.InjectFrom(partner);

        }
    }
}

据我所知，Valueinjector按类名+属性名映射复杂的对象图。我期望vm对象属性CityName为＆＃34;雅典＆＃34;注射后，它是空的。我想我错过了一些东西。帮助赞赏。
