MVC TempData问题

Question

有;        我的MVC项目中有一个非常奇怪的Tempdata问题。这是我的伪代码;

  public class MyController: Controller
  {
    public ActionResult CreateInvoiceAndCustomerContact()
    {
        return View();
    }

    [HttpPost]
    public ActionResult CreateCustomerContact_Invoice()
    {
       {
          _MyFileCreationObj.CreateTtextFile();
       }
       TempData["ResultMessage"] = "hello";
       return RedirectToAction("CreateInvoiceAndCustomerContact");
    }
}

In object _MyFileCreationObj I have a method which uses "StreamWriter" to create text file:

   public void CreateInvoiceAndCustomerContact()
   {
        using (StreamWriter writer = new StreamWriter(exportedFile))
        {
           //write text to a file
        }
   }

我遇到的问题是：       ＆＃34; TempData [＆＃34; ResultMessage＆＃34;]＆＃34;在我看来不会显示。

如果我注释掉了StreamWriter块，那么没有问题显示＆＃34; TempData [＆＃34; ResultMessage＆＃34;]＆＃34;在我看来。

有人可以请帮忙吗？

干杯 罗布。

After googling and asking question in ASP.NET forum, I finally fixed the issue: I write my text file to the "BIN" folder which causes the restart of the application pool!!! See link: Common reasons why your application pool may unexpectedly recycle That why I lost my TempData. By changing the file location, everything works now.
