配置Automapper资料类具有参数的构造和Ninject

Question

我使用Automapper（v5.1.1.0）和Ninject（v3.2.0.0）。我的个人资料类是：

public class ApplicationUserResponseProfile : Profile 
{ 
    public ApplicationUserResponseProfile(HttpRequestMessage httpRequestMessage) 
    { 
     UrlHelper urlHelper = new UrlHelper(httpRequestMessage); 
     CreateMap<ApplicationUser, ApplicationUserResponseModel>() 
      .ForMember(dest => dest.Url, opt => opt.MapFrom(src => urlHelper.Link("GetUserById", new { id = src.Id }))); 
    } 

    public ApplicationUserResponseModel Create(ApplicationUser applicationUser) 
    { 
     return Mapper.Map<ApplicationUserResponseModel>(applicationUser); 
    } 
} 

而且AutoMapperWebConfiguration是：

Mapper.Initialize(cfg => 
     { 
      cfg.AddProfile<ApplicationUserResponseProfile>(); // unable to configure 
     }); 

我也曾尝试将其绑定到Ninject内核：

var config = new MapperConfiguration(
      c => 
      { 
       c.AddProfile(typeof(ApplicationUserResponseProfile)); 
      }); 
var mapper = config.CreateMapper(); 
kernel.Bind<IMapper>().ToConstant(mapper); 

而且不同的方式：

Mapper.Initialize(cfg => 
     { 
      cfg.ConstructServicesUsing((type) => kernel.Get(type)); 
      cfg.AddProfile(typeof(ApplicationUserResponseProfile)); 
     }); 

但是得到了e RROR以两种方式 -

请帮我没有定义参数的构造函数。我无法配置AutoMapper配置文件类（其中有参数）与Ninject。有什么不同的方法可以解决这个问题吗？

我以不同的方式解决了这个问题。我已经从静态迁移automapper而不是Profile的方法。

public class ApplicationUserResponseFactory 
{ 
    private MapperConfiguration _mapperConfiguration; 
    public ApplicationUserResponseFactory(HttpRequestMessage httpRequestMessage) 
    { 
     UrlHelper urlHelper = new UrlHelper(httpRequestMessage); 
     _mapperConfiguration = new MapperConfiguration(cfg => 
     { 
      cfg.CreateMap<ApplicationUser, ApplicationUserResponseModel>() 
       .ForMember(dest => dest.Url, opt => opt.MapFrom(src => UrlHelper.Link("GetUserById", new { id = src.Id }))); 
     }); 

    } 

    public ApplicationUserResponseModel Create(ApplicationUser applicationUser) 
    { 
     return _mapperConfiguration.CreateMapper().Map<ApplicationUserResponseModel>(applicationUser); 
    } 
} 

我已经找到了迁移过程here
