这是更改我的asp.net mvc控制器以使用异步调用不同方法的方法吗？

public class HomeController : Controller
{
    private readonly IMyService _myService;

    public HomeController(IMyService myService)
    {
        _myService = myService;
    }

    public ActionResult Index()
    {
        var data = _myService.GetData();
        return View(data);
    }
}

public class HomeController : Controller
{
    private readonly IMyService _myService;

    public HomeController(IMyService myService)
    {
        _myService = myService;
    }

    public async Task<ActionResult> Index()
    {
        var data = await _myService.GetDataAsync();
        return View(data);
    }
}

public interface IMyService
{
    Task<IEnumerable<DataModel>> GetDataAsync();
}

public class MyService : IMyService
{
    public async Task<IEnumerable<DataModel>> GetDataAsync()
    {
        // 模拟异步数据库查询
        await Task.Delay(1000);
        return new List<DataModel> { /* 数据 */ };
    }
}
