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;
