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。

我尝试过以下代码将其保存在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样本）

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

使用此代码是将照片保存在某处？

如果有，任何想法在哪里？

如何更改保存位置？

Answer 1

我并非100％确定这是你所追求的，但它可能有所帮助：

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

CameraCaptureUI将图片保存在指定位置
