1、新建一个静态类

public static class ServiceLocator     {        ///        /// 服务提供程序，用于直接获取已注入的类        ///        public static IServiceProvider Instance { get; set; }     } 2、在Startup.cs中将生成器赋值给静态类属性 public void Configure(IApplicationBuilder app, IHostingEnvironment env)        {           Models.ServiceLocator.Instance = app.ApplicationServices;        } 3、操作类中通过静态类获取已注入的服务 var myRedis = ServiceLocator.Instance.GetService(typeof(MyRedis)) as MyRedis;
