如何在ASP.Net Webapp中引用的项目DLL中初始化AutoMapper配置文件

问题描述

在我的项目类库(dll)中如何使用automapper进行了一些努力.请在下面查看我整体解决方案的结构.

Struggling a little on how to use automapper in my project class libraries (dlls). See my structure of my overall solution below.

WebApp启动，并在Global.asax App Start中，调用AutoMapper.Configure()方法来添加映射配置文件.现在，我只是添加Services.AutoMapperViewModelProfile.但是我需要以某种方式考虑每个WebStoreAdapters中的配置文件(在下面的示例中为BigCommerce和Shopify).我希望不为WebApp中的每个WebStoreAdapter添加引用，只是为了能够在AutoMapperConfig期间添加配置文件.如果我在WebStoreFactory中向AutoMapper.Initialize添加另一个调用，它将覆盖WebApp中的那个调用.

The WebApp fires up, and in Global.asax App Start, the AutoMapper.Configure() method is called to add the mapping profiles. For now I am just adding the Services.AutoMapperViewModelProfile. But I need to somehow account for the profiles in each of the WebStoreAdapters (BigCommerce and Shopify in the example below). I was hoping not to add references to each WebStoreAdapter in WebApp, just for the sake of being able to add the profiles during the AutoMapperConfig. If I add another call to AutoMapper.Initialize in WebStoreFactory, it overrides the one in WebApp.

我是否还有另一种方式会以某种其他方式失踪或完全不在基地?

Is there another way that I am missing or totally off base here in some other way?

WebApp
     - AutoMapperConfig
        - AddProfile Services.AutoMapperViewModelProfile

   Services.dll
      - AutoMapperViewModelProfile

   Scheduler.dll (uses HangFire to execute cron jobs to get data from shop carts. Its UI is accessed via the WebApp)

       WebStoreAdapter.dll
            -WebStoreFactory

               BigCommerceAdapter.dll
                   - AutoMapperBigCommerceDTOProfile

               ShopifyAdapter.dll
                   - AutoMapperShopifyDTOProfile

从Global.asax中调用初始化:

Initializing as called from Global.asax:

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

个人资料:

public class AutoMapperViewModelProfile : Profile
{
    public override string ProfileName
    {
        get { return this.GetType().ToString(); }
    }

    protected override void Configure()
    {
        CreateMap<InventoryContainerHeader, InventoryContainerLabelPrintZPLViewModel>()
                .ForMember(vm => vm.StatusDescription, opt => opt.MapFrom(entity => entity.InventoryContainerStatus.DisplayText))
                .ForMember(dest => dest.ContainerDetails, option => option.Ignore())
                ;
        ...
   }
}

推荐答案

一种方法是使用反射来加载所有配置文件:

One way to do this is to use reflection to load up all profiles:

        var assembliesToScan = AppDomain.CurrentDomain.GetAssemblies();
        var allTypes = assembliesToScan.SelectMany(a => a.ExportedTypes).ToArray();

        var profiles =
            allTypes
                .Where(t => typeof(Profile).GetTypeInfo().IsAssignableFrom(t.GetTypeInfo()))
                .Where(t => !t.GetTypeInfo().IsAbstract);

        Mapper.Initialize(cfg =>
        {
            foreach (var profile in profiles)
            {
                cfg.AddProfile(profile);
            }
        });

您没有直接引用任何一个Automapper配置文件，而只是从当前AppDomain加载所有配置文件.

You don't directly reference any one Automapper profile, but just load all Profile's from the current AppDomain.
