问如何在 ASP.NET Core 中创建一个依赖注入的作用域，并在该作用域内获取服务的实例？

public interface IMyService
{
    void DoWork();
}

public class MyService : IMyService
{
    public void DoWork()
    {
        // 实现你的逻辑
    }
}

public void ConfigureServices(IServiceCollection services)
{
    services.AddControllersWithViews();
    services.AddScoped<IMyService, MyService>();
}

public class MyClass
{
    private readonly IServiceProvider _serviceProvider;

    public MyClass(IServiceProvider serviceProvider)
    {
        _serviceProvider = serviceProvider;
    }

    public void MyMethod()
    {
        using (var scope = _serviceProvider.CreateScope())
        {
            var myService = scope.ServiceProvider.GetRequiredService<IMyService>();
            myService.DoWork();
        }
    }
}

public class HomeController : Controller
{
    private readonly MyClass _myClass;

    public HomeController(MyClass myClass)
    {
        _myClass = myClass;
    }

    public IActionResult Index()
    {
        _myClass.MyMethod();
        return View();
    }
}

public void ConfigureServices(IServiceCollection services)
{
    services.AddControllersWithViews();
    services.AddScoped<IMyService, MyService>();
    services.AddTransient<MyClass>(); // 或者 AddScoped 或 AddSingleton，根据你的需求
}
