如何将 ConfigureServices 方法(启动)拆分为多个文件 [英] How to Split ConfigureServices method (of Startup) into multiple files

问题描述

关注点分离 (SoC)

在 ConfigureServices 中注册的依赖指令(启动类的方法)由不同的 DI 组成，如 Repository、Fluent Validations 等.

Dependency injunction registrtered in ConfigureServices (method of startup class) consist of different DI's like Repository, Fluent Validations etc.

我将如何将 DI 注册分成单独的文件(如下所示)

推荐答案

创建一个扩展方法来保存你想要的任何附加配置

Create an extension method to hold any additional configuration you want

public static class MyExtensions {
    public static IServiceCollection AddFluentValidation(this IServiceCollection services) {

        //...add services

        return services;
    }
}

然后在Startup

public void ConfigureServices(IServiceCollection services) {

    //...

    services.AddFluentValidation();
    services.AddRepository();

    //...

}

使用扩展方法填充服务集合是框架和第 3 方扩展常用的方法.

The use of extension methods for populating the services collection is commonly used by the framework and 3rd party extensions.
