原文: .Net Core3.0依赖注入DI 构建ASP.NET Core应用程序的时候，依赖注入已成为了.NET Core的核心，这篇文章，我们理一理依赖注入的使用方法。 不使用依赖注入 首先，我们创建一个ASP.NET Core Mvc项目，定义个表达的爱服务接口，中国小伙类实现这个类如下： public interface ISayLoveService { string SayLove(); } public class CNBoyService : ISayLoveService { public string SayLove() { return "安红，我喜欢你"; } } 在LoveController 控制器中调用 ISayLoveService的SayLove方法。 public class LoveController : Controller { private ISayLoveService loveService; public IActionResult Index() { loveService = new CNBoyService(); //中国小伙对安红的表达 ViewData["SayLove"] = loveService.SayLove(); return View(); } } 输出如图: 小结

获取ASP.NET Core中所有注入(DI)服务，在ASP.NET Core中加入了Dependency Injection依赖注入。 我们在Controller，或者在ASP.NET Core程序中的其他地方使用注入的服务，如logging 等。 我们要怎样获取ASP.NET Core中所有注入(DI)服务呢，下面我们来一探究竟， 也可以来看看ASP.NET Core到底注入了哪些服务。 依赖注入简单介绍： 依赖注入（Dependency injection , DI）是一种实现对象及其合作者或依赖项之间松散耦合的技术。将类用来执行其操作的这些对象以某种方式提供给该类，而不是直接实例化合作者或使用静态引用。 我们新建一个ASP.NET Core 空应用程序。 然后Startup 中定义一个变量 private IServiceCollection _services; public class Startup { private IServiceCollection _services; // This method gets called by the runtime. Use this method to add services to the container. // For more information on how to configure your
