UWP StorageFile 的 CopyAsync 在发布版本中不起作用，抛出异常

Question

I need to copy an icon file in C:// drive due to the first run of my UWP FullTrust Application. Here below is my code, which is working properly in Debug mode but not works in Release mode.

var packagePath = Package.Current.InstalledLocation;
var srcPath = Path.Combine(packagePath.Path, "Assets\\Systray_icon.ico");

Windows.Storage.StorageFile storageFile = await Windows.Storage.StorageFile.GetFileFromPathAsync(srcPath);

Windows.Storage.StorageFolder storageFolder = await Windows.Storage.StorageFolder.GetFolderFromPathAsync("C:\\");
await storageFolder.CreateFolderAsync("MyAppFolder", CreationCollisionOption.ReplaceExisting);

Windows.Storage.StorageFolder sf = await Windows.Storage.StorageFolder.GetFolderFromPathAsync("C:\\MyAppFolder\\");

await storageFile.CopyAsync(sf);

The folder has been created in both Debug and Release mode but due to copy throws an exception in release mode.

The system cannot find the file specified. (Exception from HRESULT: 0x80070002)

Any kind of help will be appreciable. Thanks in advance.

Answer 1

The problem has been resolved. In release mode, folder creation was taking time sometimes as I didn't use Task in asynchronous await due to folder creation. So I'm posting workable code samples for others' help.

public void IconCopy()
{
   LOG(LogLevel.Standard, $"[IconCopy][+] ");
   try
   {
       var packagePath = Package.Current.InstalledLocation;
       var srcPath = Path.Combine(packagePath.Path, "Assets\\Systray_icon.ico");
       Windows.Storage.StorageFile storageFile = await Windows.Storage.StorageFile.GetFileFromPathAsync(srcPath);

       await CreateContextMenuIconFolder();

       Windows.Storage.StorageFolder sf = await Windows.Storage.StorageFolder.GetFolderFromPathAsync("C:\\MyAppFolder\\");
       await storageFile.CopyAsync(sf);
   }
   catch (Exception ex)
   {
      LOG(LogLevel.Error, $"[IconCopy] Exception occured : {ex.Message.ToString()}");
   }

   LOG(LogLevel.Standard, $"[IconCopy][-] ");
}

public async Task CreateContextMenuIconFolder()
{
  LOG(LogLevel.Standard, $"[CreateContextMenuIconFolder][+] "); 

  try
  {
      Windows.Storage.StorageFolder storageFolder = await Windows.Storage.StorageFolder.GetFolderFromPathAsync("C:\\");
      await storageFolder.CreateFolderAsync("MyAppFolder", CreationCollisionOption.ReplaceExisting);
  }
  catch(Exception ex)
  {
     LOG(LogLevel.Error, $"[CreateContextMenuIconFolder] Exception occured : {ex.Message.ToString()}");
  }

  LOG(LogLevel.Standard, $"[CreateContextMenuIconFolder][-] ");
}
