C# 使用参数构造函数和Ninject配置Automapper配置文件类

我使用的是

Automapper

（v5.1.1.0）和

Ninject

（v3.2.0.0）。我的个人资料类别是：

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);
    }
}

但两方面都有错误-

没有为此对象定义无参数构造函数

---

请帮帮我。我无法使用

Ninject

配置

AutoMapper

配置文件类（具有参数）。有什么不同的方法来解决这个问题吗？

我用不同的方法解决了这个问题。我已经从静态迁移了

automapper

，而不是

Profile

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);
    }
}

公共类ApplicationUserResponseFactory
{
私有MapperConfiguration\u MapperConfiguration；
公共应用程序SerResponseFactory（HttpRequestMessage HttpRequestMessage）
{
UrlHelper UrlHelper=新的UrlHelper（httpRequestMessage）；
_mapperConfiguration=新的mapperConfiguration（cfg=>
{
cfg.CreateMap
您可以创建如下解析程序：

public class YourResolver : IValueResolver<ApplicationUser, ApplicationUserResponseModel, string>
{
    HttpRequestMessage HttpRequestMessage { get; }
  
    public YourResolver(HttpRequestMessage httpRequestMessage)
    {
      HttpRequestMessage = httpRequestMessage;
    }
  
    public string Resolve(ApplicationUser source, ApplicationUserResponseModel destination, string destMember, ResolutionContext context)
    {
       //do something with your HttpRequestMessage and return a value;
    }
}

公共类YourResolver:IValueResolver

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

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);
    }
}

public class YourResolver : IValueResolver<ApplicationUser, ApplicationUserResponseModel, string>
{
    HttpRequestMessage HttpRequestMessage { get; }
  
    public YourResolver(HttpRequestMessage httpRequestMessage)
    {
      HttpRequestMessage = httpRequestMessage;
    }
  
    public string Resolve(ApplicationUser source, ApplicationUserResponseModel destination, string destMember, ResolutionContext context)
    {
       //do something with your HttpRequestMessage and return a value;
    }
}

public class ApplicationUserResponseProfile : Profile
{
    public ApplicationUserResponseProfile()
    {
        CreateMap<ApplicationUser, ApplicationUserResponseModel>()
                 .ForMember(dest => dest.Url, opt => opt.MapFrom<YourResolver>());
    }
}
