Question

The following code snippet is causing a compilation error that I am hard to understand.

Error 1 Cannot await System.Collections.Generic.List'<BusinessLogic.News>’

Any suggestions?

public class NewsController : Controller
{
    public async Task<ActionResult> Index(int page=1)
    {
        NewsNavigator News = new NewsNavigator();
        await News.Load(page);
        ...

        return View(News);
    }
}



    public List<News> Load(int page = DefaultPage, int pageSize = DefaultPageSize, string filter = DefaultFilter)
    {
        //DBLayer_News
        ...
        return LoadedNews;
    }

Answer 1

Await is applied to the result of a method call that returns a Task.

You cannot call it on News because News isn’t a Task. Create a Task and pass your News.Load method to it.

NewsNavigator News = new NewsNavigator();
var newsLoadTask = Task.Factory.StartNew(() => News.Load(page));
await newsLoadTask;
