c＃windows phone下载文件夹 [英] c# windows phone Downloads folder

问题描述

根据 http：// msdn。 microsoft.com/en-us/library/windows/apps/hh202959(v=vs.105).aspx [ ^ ]

i创建一个backgroundtransfer。我想在下载完成后，该文件移动到根目录下载文件夹（手机或SD卡/下载）。我不知道怎么做，微软改变了Windows Phone上的所有代码。



microsoft在该主题上写了一段代码>

  case  TransferStatus.Completed：
 
  //  如果已完成转移的状态代码为200或206，则 
  //  转移成功 
  if （transfer.StatusCode ==  200  || transfer.StatusCode ==  206 ）
 {
  / /  删除转移请求以便在 
  // 中腾出空间队列以获得更多转移。转移不会自动 
  //  被系统删除。 
 RemoveTransferRequest（transfer.RequestId）; 
 
  //  在此示例中，下载的文件将移至根 
  //  隔离存储目录 
  using （IsolatedStorageFile isoStore = IsolatedStorageFile.GetUserStoreForApplication（））
 {
  string  filename = transfer.Tag; 
  if （isoStore.FileExists（filename））
 {
 isoStore.DeleteFile（filename）; 
} 
 isoStore.MoveFile（transfer.DownloadLocation.OriginalString，filename）; 
} 
} 

但是我不知道那个文件在哪里搬了！



请给我一个代码。非常感谢

Hi, according to http://msdn.microsoft.com/en-us/library/windows/apps/hh202959(v=vs.105).aspx[^]
i create a backgroundtransfer. i want when download is completed, that file moves to "Downloads Folder on root directory" (Phone or SD Card/Downloads). i don't know how can i make it, microsoft changes all codes on Windows Phone.

microsoft wrote a code on that topic>

case TransferStatus.Completed:

  // If the status code of a completed transfer is 200 or 206, the
  // transfer was successful
  if (transfer.StatusCode == 200 || transfer.StatusCode == 206)
  {
    // Remove the transfer request in order to make room in the
    // queue for more transfers. Transfers are not automatically
    // removed by the system.
    RemoveTransferRequest(transfer.RequestId);

    // In this example, the downloaded file is moved into the root
    // Isolated Storage directory
    using (IsolatedStorageFile isoStore = IsolatedStorageFile.GetUserStoreForApplication())
    {
      string filename = transfer.Tag;
      if (isoStore.FileExists(filename))
      {
        isoStore.DeleteFile(filename);
      }
      isoStore.MoveFile(transfer.DownloadLocation.OriginalString, filename);
    }
  }

but i dont know where goes that file when moved!

please give me a code. thanks alot
