ASP. NET MVC 显示在等待阿辛基行动时的等候页
原标题:ASP.NET MVC showing a waiting page whilst waiting for Async Operation

我把该守则撤回到这里的基本内容,但我要说的是,要显示我们等待的用户,然后打电话,而任务等到5秒钟才完成,我然后想再说另一种看法,表明用户的任务已经完成了下面的一些例子,加上一些评论。

public class Test : Controller
{
    public IActionResult Index()
    {
        // Show the User they are Waiting by returning a view with a label telling them
        return View("Waiting");

        // Then I want to call BeginTask and once its async operation is completed
        // Once beginTask is completed I want to show a different view telling the user the task is completed
    }

    public IActionResult Waiting()
    {
        return View();
    }

    public async Task BeginTask()
    {
        await Task.Delay(5000);
    }

    public IActionResult Completed()
    {
        return View();
    }
}
