如何在AutoMapper中扫描和自动配置配置文件？ [英] How to scan and auto-configure profiles in AutoMapper?

问题描述

是否可以自动配置Automapper来扫描名称空间/程序集中的所有配置文件？我想做的是从给定的接口过滤的给定程序集中将映射配置文件添加到AutoMapper中，例如StructureMap中的扫描约定：

Is there any way to auto-configue Automapper to scan for all profiles in namespace/assembly? What I would like to do is to add mapping profiles to AutoMapper from given assembly filtered by given interface, something like Scan Conventions in StructureMap:

    public static void Configure()
    {
        ObjectFactory.Initialize(x =>
            {
                // Scan Assembly
                x.Scan(
                    scanner =>
                    {
                        scanner.TheCallingAssembly();
                        scanner.Convention<MyCustomConvention>();
                        scanner.WithDefaultConventions();
                    });

                // Add Registries
                x.AddRegistry(new SomeRegistry());
            });

        Debug.WriteLine(ObjectFactory.WhatDoIHave());
    }

public class MyCustomConvention : IRegistrationConvention
{
    public void Process(Type type, Registry registry)
    {
        if (!type.CanBeCastTo(typeof(IMyType)))
        {
            return;
        }

        string name = type.Name.Replace("SomeRubishName", String.Empty);
        registry.AddType(typeof(IMyType), type, name);            
    }

我尝试使用SelfConfigure，但是找不到有关如何配置的任何文档使用它来过滤配置文件：

I've tried to use SelfConfigure but can't find any documentation on how to use it to filter out profiles:

    public static void Configure()
    {
        Mapper.Initialize(x =>
                              {
                                  // My Custom profile
                                  x.AddProfile<MyMappingProfile>();

                                  // Scan Assembly
                                  x.SelfConfigure(Assembly.GetCallingAssembly());
                              });
    }

另一个问题是如何报告所有已初始化的地图/配置文件（类似

Another question is how can I report all maps/profiles already initialized (something like ObjectFactory.WhatDoIHave() in StructureMap)?

推荐答案

我也在搜索时找到了这篇文章，但这就是我实现自动映射方案：

I found this post while searching as well, but this is how I implemented an auto mapping scheme:

public class MyCustomMap : Profile
{
    protected override void Configure()
    {
        CreateMap<MyCustomViewModel, MyCustomObject>()
            .ForMember(dest => dest.Phone,
                        opt => opt.MapFrom(
                        src => src.PhoneAreaCode + src.PhoneFirstThree + src.PhoneLastFour));
    }
}

public static class AutoMapperConfiguration
{
    public static void Configure()
    {
        Mapper.Initialize(x => GetConfiguration(Mapper.Configuration));
    }

    private static void GetConfiguration(IConfiguration configuration)
    {
        var profiles = typeof(MyCustomMap).Assembly.GetTypes().Where(x => typeof(Profile).IsAssignableFrom(x));
        foreach (var profile in profiles)
        {
            configuration.AddProfile(Activator.CreateInstance(profile) as Profile);
        }
    }
}

因此，当我的应用程序启动时，我只叫

So when my application starts, all I call is

AutoMapperConfiguration.Configure(); 

我的所有地图都已注册。

And all my maps are registered.
