无法看到在哪里初始化映射.

Cannot see where you initialize the mapping.

解决方案:

您可以创建您的映射配置文件，例如:

You can create your mapping profile, for example:

public class MappingProfile : Profile
{
    public MappingProfile()
    {
       CreateMap<Company, CompanyFormViewModel>()
          .ForMember(vm => vm.Id, map => map.MapFrom(m => m.Id))
          .ForMember(vm => vm.Name, map => map.MapFrom(m => m.Name))
          .ForMember(vm => vm.Owner, map => map.MapFrom(m => m.Owner))
          .ForMember(vm => vm.Email, map => map.MapFrom(m => m.Email))
          .ForMember(vm => vm.Password, map => map.MapFrom(m => m.Password))
          .ForMember(vm => vm.Address, map => map.MapFrom(m => m.Address));
       CreateMap<CompanyFormViewModel, Company>()
          .ForMember(m => m.Id, map => map.MapFrom(vm => vm.Id))
          .ForMember(m => m.Name, map => map.MapFrom(vm => vm.Name))
          .ForMember(m => m.Owner, map => map.MapFrom(vm => vm.Owner))
          .ForMember(m => m.Email, map => map.MapFrom(vm => vm.Email))
          .ForMember(m => m.Password, map => map.MapFrom(vm => vm.Password))
          .ForMember(m => m.Address, map => map.MapFrom(vm => vm.Address)); 

    }
}

然后在Global.asax.cs

    public class AutoMapperConfiguration
    {
        public static void Configure()
        {
            Mapper.Initialize(x =>
            {
                x.AddProfile<MappingProfile>();
            });

            Mapper.Configuration.AssertConfigurationIsValid();               
        }
    }

最后，不要忘记在Application_Start()

//Configure Automapper
AutoMapperConfiguration.Configure();
