CameraCaptureUI 在指定位置保存图片

Question

我正在使用 CameraCaptureUI API 在 windows 平板电脑上拍照。我可以拍照，但我不知道它保存在哪里或如何更改它的保存文件夹。

我试过用下面的代码将它保存到图片库中，但没有成功:
Dim fileCopy As StorageFile = Await file.CopyAsync(KnownFolders.PicturesLibrary, "MyNicePhoto.bmp", NameCollisionOption.ReplaceExisting)

这是我用来拍照的代码（取自 CameraCaptureUI 示例）

Private appSettings As Windows.Foundation.Collections.IPropertySet
Private Const photoKey As String = "capturedPhoto" 

 Try
    ' Using Windows.Media.Capture.CameraCaptureUI API to capture a photo
    Dim dialog As New CameraCaptureUI()
    Dim aspectRatio As New Size(16, 9)
    dialog.PhotoSettings.CroppedAspectRatio = aspectRatio

    Dim file As StorageFile = Await dialog.CaptureFileAsync(CameraCaptureUIMode.Photo)
    If file IsNot Nothing Then
        Dim bitmapImage As New BitmapImage()
        Using fileStream As IRandomAccessStream = Await file.OpenAsync(FileAccessMode.Read)
            bitmapImage.SetSource(fileStream)
        End Using

        ' Store the file path in Application Data
        appSettings(photoKey) = file.Path

    End If
Catch ex As Exception
End Try

使用此代码将图片保存到某处吗？

如果有，知道在哪里吗？

如何更改保存位置？

我不是 100% 确定这就是您想要的，但它可能会有所帮助：

Dim saveDiag As New Pickers.FolderPicker
Dim destFolder As Windows.Storage.StorageFolder = Await SaveDiag.PickSingleFolderAsync
Await file.MoveAsync(destFolder)
