How to access .NET AutoMapper configuration access when using assembly scanning?

问题

在使用程序集扫描来注册配置文件时，我能否获取 AutoMapper 配置实例的访问权限？
https://docs.automapper.org/en/latest/Dependency-injection.html

我之前使用了 ForAllMaps() 来为所有映射添加一个通用的 IgnoreUnmappedProperties()。

  1. public static class AutoMapperExtensions
  2. {
  3.     private static void IgnoreUnmappedProperties(TypeMap map, IMappingExpression expr)
  4.     {
  5.         foreach (string propName in map.GetUnmappedPropertyNames())
  6.         {
  7.             if (map.SourceType.GetProperty(propName) != null)
  8.             {
  9.                 expr.ForSourceMember(propName, opt => opt.Ignore());
  10.             }
  11.             if (map.DestinationType.GetProperty(propName) != null)
  12.             {
  13.                 expr.ForMember(propName, opt => opt.Ignore());
  14.             }
  15.         }
  16.     }
  18.     public static void IgnoreUnmapped(this IProfileExpression profile)
  19.     {
  20.         profile.ForAllMaps(IgnoreUnmappedProperties);
  21.     }
  23.     public static void IgnoreUnmapped(this IProfileExpression profile, Func<TypeMap, bool> filter)
  24.     {
  25.         profile.ForAllMaps((map, expr) =>
  26.         {
  27.             if (filter(map))
  28.             {
  29.                 IgnoreUnmappedProperties(map, expr);
  30.             }
  31.         });
  32.     }
  34.     public static void IgnoreUnmapped(this IProfileExpression profile, Type src, Type dest)
  35.     {
  36.         profile.IgnoreUnmapped((TypeMap map) => map.SourceType == src && map.DestinationType == dest);
  37.     }
  39.     public static void IgnoreUnmapped<TSrc, TDest>(this IProfileExpression profile)
  40.     {
  41.         profile.IgnoreUnmapped(typeof(TSrc), typeof(TDest));
  42.     }
  43. }

我看不到如何在新的依赖注入模式中添加这个功能。是否有人可以指向我需要完成此操作的文档，或告诉我是否应该使用其他模式来实现相同的功能？：o）

I had previously used ForAllMaps() to add a generic IgnoreUnmappedProperties() for all mappings.

  1. public static class AutoMapperExtensions
  2. {
  3.     private static void IgnoreUnmappedProperties(TypeMap map, IMappingExpression expr)
  4.     {
  5.         foreach (string propName in map.GetUnmappedPropertyNames())
  6.         {
  7.             if (map.SourceType.GetProperty(propName) != null)
  8.             {
  9.                 expr.ForSourceMember(propName, opt =&gt; opt.Ignore());
  10.             }
  11.             if (map.DestinationType.GetProperty(propName) != null)
  12.             {
  13.                 expr.ForMember(propName, opt =&gt; opt.Ignore());
  14.             }
  15.         }
  16.     }
  18.     public static void IgnoreUnmapped(this IProfileExpression profile)
  19.     {
  20.         profile.ForAllMaps(IgnoreUnmappedProperties);
  21.     }
  23.     public static void IgnoreUnmapped(this IProfileExpression profile, Func&lt;TypeMap, bool&gt; filter)
  24.     {
  25.         profile.ForAllMaps((map, expr) =&gt;
  26.         {
  27.             if (filter(map))
  28.             {
  29.                 IgnoreUnmappedProperties(map, expr);
  30.             }
  31.         });
  32.     }
  34.     public static void IgnoreUnmapped(this IProfileExpression profile, Type src, Type dest)
  35.     {
  36.         profile.IgnoreUnmapped((TypeMap map) =&gt; map.SourceType == src &amp;&amp; map.DestinationType == dest);
  37.     }
  39.     public static void IgnoreUnmapped&lt;TSrc, TDest&gt;(this IProfileExpression profile)
  40.     {
  41.         profile.IgnoreUnmapped(typeof(TSrc), typeof(TDest));
  42.     }
  44. }

I am not seeing how I might add this in the new DI pattern. Can someone point me to the docs I need to accomplish this, or tell me I'm dumb and should use this other pattern to achieve the same thing? : o)

有.AddAutoMapper() 的重载版本，接受一个 Action<IMapperConfigurationExpression> 或者 Action<IServiceProvider, IMapperConfigurationExpression> 作为第一个参数。

例如：

  1.     private static void ConfigureAutoMapper(this IServiceCollection services)
  2.     {
  3.         services.AddAutoMapper(
  4.            config => config.ForAllMaps(IgnoreUnmappedProperties),
  5.            new List<Assembly> { typeof(AutoMapperExtensions).Assembly });
  6.     }
英文:

There are overrides of .AddAutoMapper() that accept an Action&lt;IMapperConfigurationExpression&gt; or even Action&lt;IServiceProvider, IMapperConfigurationExpression&gt; as the first argument.

For instance:

  1.     private static void ConfigureAutoMapper(this IServiceCollection services)
  2.     {
  3.         services.AddAutoMapper(
  4.            config =&gt; config.ForAllMaps(IgnoreUnmappedProperties),
  5.            new List&lt;Assembly&gt; { typeof(AutoMapperExtensions).Assembly });
  6.     }
