如何映射2個具有4個不同屬性類的對象？

我有6個班，我想與AutoMapper如何映射2個具有4個不同屬性類的對象？

public class Alert 
     { 
       public string MessageSender { get; set; } 
       public Site Site { get; set; } 
       public IEnumerable<Recipient> Recipients { get; set; } 
     } 

public class AlertModel 
    { 
     public string Sender { get; set; } 
     public SiteModel Site { get; set; } 
     public IEnumerable<RecipientModel> Recipients { get; set; } 
} 


public class Site 
    { 
     public int Id { get; set; } 
    } 

public class SiteModel 
    { 
     public int Id { get; set; } 
    } 

public class Recipient 
    { 
     public int Id { get; set; } 
     public string CallId { get; set; } 
    } 

public class RecipientModel 
    { 
     public int Id { get; set; } 
     public string CallId { get; set; } 
    } 


    private static void ConfigureAlertMapping() 
    { 
     AutoMapper.Mapper.Initialize(cfg => 
      cfg.CreateMap<Alert, AlertModel>() 
       .ForMember(dest => dest.Sender, opt => opt.MapFrom(src => src.MessageSender)) 
     ); 
    } 

    private static void ConfigureRecipientMapping() 
    { 
     AutoMapper.Mapper.Initialize(cfg => cfg.CreateMap<Recipient, RecipientModel>()); 
    } 

    private static void ConfigureSiteMapping() 
    { 
     AutoMapper.Mapper.Initialize(cfg => cfg.CreateMap<Site, SiteModel>()); 
    }

到MAPP他們這是我要地圖的對象。

Alert alert = new Alert() 
     { 
      Site = new Site() { Id = 1 }, 
      Recipients = new List<Recipient> { new Recipient() { CallId = "1001" } } 
     };

我要打電話這一點，但拋出一個異常... :(

AlertModel alertOutputInfo = AutoMapper.Mapper.Map<Alert, AlertModel>(alert);

這是錯誤：

>>Mapping types: 
Alert -> AlertModel 
UniteAlerter.Domain.Models.Alert -> UniteAlerter.Gateway.Models.AlertModel 
    at lambda_method(Closure , Alert , AlertModel , ResolutionContext) 
    at AutoMapper.Mapper.AutoMapper.IMapper.Map[TSource,TDestination](TSource source) 
    at AutoMapper.Mapper.Map[TSource,TDestination](TSource source) 
    at UniteAlerter.Gateway.AlertGateway.<SendAlert>d__1.MoveNext() 
--- End of stack trace from previous location where exception was thrown --- 
    at System.Runtime.CompilerServices.TaskAwaiter.ThrowForNonSuccess(Task task) 
    at System.Runtime.CompilerServices.TaskAwaiter.HandleNonSuccessAndDebuggerNotification(Task task) 
    at System.Runtime.CompilerServices.TaskAwaiter`1.GetResult()

如果你會發現另一種解決方案，請在此處添加它

你能否提供你的映射配置 – Shevek

當然，你需要向下滾動第一個代碼註釋（最後3個方法）。 – Alex

我將這些方法稱爲Configure，在Startup - > ConfigureServices（IServiceCollection services） – Alex

UPDATE（SOLUTION）

我發現了這個問題......我爲每個想要映射的類初始化映射器，但解決方案是用所有映射初始化映射器一次。

AutoMapper.Mapper.Initialize(
cfg => 
    { 
     cfg.CreateMap<Alert, AlertModel>().ForMember(dest => dest.Sender, opt => opt.MapFrom(src => src.MessageSender)); 
     cfg.CreateMap<Recipient, RecipientModel>(); 
     cfg.CreateMap<Site, SiteModel>(); 
     } 
);
