传递的CurrentUICulture以异步任务在ASP.NET MVC 3.0 [英] Pass CurrentUICulture to Async Task in ASP.NET MVC 3.0

问题描述

主动语言从URL来确定，然后设置

The active language is determined from the url and then set on the

Thread.CurrentThread.CurrentUICulture = cultureInfo;
Thread.CurrentThread.CurrentCulture = CultureInfo.CreateSpecificCulture(cultureInfo.Name);

翻译是从正确的资源文件中检索的方式。

That way the translations are retrieved from the correct resource files.

当使用控制器的异步操作，我们有一个后台线程，其中Thread.CurrentThread.CurrentUICulture重新设置为默认的操作系统。同时也对后台线程，我们需要正确的语言。

When using Async action on controllers, we have a background thread, where the Thread.CurrentThread.CurrentUICulture is set back to OS default. But also on the background thread we need the correct language.

我创建了一个TaskFactory延伸至文化传递给后台线程，它看起来是这样的：

I created a TaskFactory extension to pass the culture to the background thread and it looks like this:

public static Task StartNew(this TaskFactory taskFactory, Action action, CultureInfo cultureInfo)
{
    return taskFactory.StartNew(() =>
    {
         Thread.CurrentThread.CurrentUICulture = cultureInfo;
         Thread.CurrentThread.CurrentCulture = CultureInfo.CreateSpecificCulture(cultureInfo.Name);

         action.Invoke();
     });
}

这可以让我做一个动作控制器以下内容：

This allows me to do the following in an action controller:

 [HttpPost]
 public void SearchAsync(ViewModel viewModel)
 {
     AsyncManager.OutstandingOperations.Increment();
     AsyncManager.Parameters["task"] = Task.Factory.StartNew(() =>
     {
         try
         {
               //Do Stuff
               AsyncManager.Parameters["viewModel"] = viewModel;
         }
         catch (Exception e)
         {
             ModelState.AddModelError(string.Empty, ResxErrors.TechnicalErrorMessage);
         }
         finally
         {
             AsyncManager.OutstandingOperations.Decrement();
         }
     }, Thread.CurrentThread.CurrentUICulture);
 }



 public ActionResult SearchCompleted(Task task, ViewModel viewModel)
 {
     //Wait for the main parent task to complete. Mainly to catch all exceptions.
     try { task.Wait(); }
     catch (AggregateException ae) { throw ae.InnerException; }

     return View(viewModel);
 }

这所有的作品完美，但我确实有一些顾虑。

This all works perfectly, but I do have some concerns.

这是通过调用原有的动作之前设置的文化来扩展动作的正确方法？

Is this the correct way to extend an action by setting the culture before invoking the original action ?

有谁知道不同的方式来德的CurrentUICulture传递给后台线程ASP.NET MVC的异步操作？

Does anyone know of a different way to pass te CurrentUICulture to a background thread for ASP.NET MVC Async actions ?

• 会话不是一个选项。


• 我想使用的CallContext中。

在这个$ C $（c）任何其他意见？

Any other comments on this code ?

感谢
