在Asp.net核心中，依赖注入，如何在单例对象中做作用域obj

// 定义作用域对象
public interface IScopedObject
{
    void DoSomething();
}

// 实现作用域对象
public class ScopedObject : IScopedObject
{
    public void DoSomething()
    {
        // 实现作用域对象的功能
    }
}

// 定义单例对象
public class SingletonObject
{
    private readonly IScopedObject _scopedObject;

    public SingletonObject(IScopedObject scopedObject)
    {
        _scopedObject = scopedObject;
    }

    public void DoSomethingWithScopedObject()
    {
        _scopedObject.DoSomething();
    }
}

// 在Startup.cs中配置依赖注入容器
public void ConfigureServices(IServiceCollection services)
{
    // 注册作用域对象
    services.AddScoped<IScopedObject, ScopedObject>();

    // 注册单例对象
    services.AddSingleton<SingletonObject>();
}

// 在控制器或其他地方使用单例对象
public class MyController : Controller
{
    private readonly SingletonObject _singletonObject;

    public MyController(SingletonObject singletonObject)
    {
        _singletonObject = singletonObject;
    }

    public IActionResult Index()
    {
        _singletonObject.DoSomethingWithScopedObject();
        return View();
    }
}
