AddAutoMapper不会在asp.net核心中加载所有程序集

本文介绍了AddAutoMapper不会在asp核心中加载所有程序集的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！ 问题描述

我有以下代码将自动映射器添加到我的应用中.

I have the following code that add automapper to my app.

public void ConfigureServices(IServiceCollection services) { services.AddMvc().SetCompatibilityVersion(CompatibilityVersion.Version_2_2); services.AddHttpClient(); services.AddAutoMapper(AppDomain.CurrentDomain.GetAssemblies()); }

AppDomain.CurrentDomain.GetAssemblies()仅返回在调用时加载的程序集.我可以看到某些包含我的映射的程序集尚未加载，结果未加载映射，这会向我返回有关缺少映射类型的错误.

The AppDomain.CurrentDomain.GetAssemblies() returns only assemblies that were loaded at the time it is called. I can see that some of my assemblies which contain my mappings have not been yet loaded and as a result mappings are not loaded which returns me errors about missing map types.

如何获取我的项目引用的所有程序集?

How do I get all assemblies referenced by my project?

推荐答案

参考-来自AutoMapper官方文档

ASP.NET Core

有一个 NuGet包与此处中所述的默认注入机制，并在此项目.

There is a NuGet package to be used with the default injection mechanism described here and used in this project.

您使用配置文件定义配置.然后你让AutoMapper知道这些配置文件在哪些程序集中定义在以下位置调用 IServiceCollection 扩展方法 AddAutoMapper 启动:

You define the configuration using profiles. And then you let AutoMapper know in what assemblies are those profiles defined by calling the IServiceCollection extension method AddAutoMapper at startup:

services.AddAutoMapper(profileAssembly1, profileAssembly2 /*, ...*/);

或标记类型:

services.AddAutoMapper(typeof(ProfileTypeFromAssembly1), typeof(ProfileTypeFromAssembly2) /*, ...*/);

现在，您可以在运行时将AutoMapper注入服务/控制器:

Now you can inject AutoMapper at runtime into your services/controllers:

public class EmployeesController { private readonly IMapper _mapper; public EmployeesController(IMapper mapper) => _mapper = mapper; // use _mapper.Map or _mapper.ProjectTo }
