asp.net-mvc – 如何判断MVC AsyncController线程是否在ASP.NET

Thread.CurrentThread或其他地方是否有属性我可以检查以确定线程的运行位置？

这是我正在执行的代码示例

public class HomeController : AsyncController
{
    public void CarsComplexAsync(string make)
    {
        AsyncManager.OutstandingOperations.Increment(2);

        System.Diagnostics.Debug.WriteLine("Enter CarsComplexAsync: " + DateTime.Now);

        Action getCarsAsync = () =>
        {
            List<Car> cars = CarService.GetCars(make);
            AsyncManager.Parameters["cars"] = cars;
            AsyncManager.OutstandingOperations.Decrement();    
        };


        Action getTrucksAsync = () =>
        {
            List<Car> trucks = CarService.GetTrucks(make);
            AsyncManager.Parameters["trucks"] = trucks;
            AsyncManager.OutstandingOperations.Decrement();
        };


        getCarsAsync.BeginInvoke(null,null);
        getTrucksAsync.BeginInvoke(null,null);
    }

public ActionResult CarsComplexCompleted(List<Car> cars,List<Car> trucks)
{
cars.AddRange(trucks);
return View(cars);
}

public static class CarService
{
    private static List<Car> _cars = new List<Car>
                {
                    new Car{ Make = "Ford",Model = "F-150",Color = "White",Year = 2010},new Car{ Make = "Chevy",Model = "Camero",Color = "Black",Year = 1984},new Car{ Make = "Peugeot",Model = "406 Coupe",new Car{ Make = "Dodge",Model = "Charger",Color = "Red",Year = 1974}
                };

    public static List<Car> GetCars(string model)
    {
        Thread.Sleep(5000);
        List<Car> cars = _cars;
        return cars;
    }

    public  static List<Car> GetTrucks(string make)
    {
        Thread.Sleep(5000);
        List<Car> cars = _cars;
        return cars;
    }
}
