接收图像-UWP

Question

I m using VS 2017, and I need to receive Image form other app. So its basically App-App Communication. I m new in UWP and windows mobile developing, so I research a lot, and I manage to get DataPackage with shared content.

When you try to examine this:

if (this.shareOperation.Data.Contains(StandardDataFormats.Bitmap))
{
    this.sharedBitmapStreamRef = await this.shareOperation.Data.GetBitmapAsync();

    //catch (Exception ex)
    //{
    //    NotifyUserBackgroundThread("Failed GetBitmapAsync - " + ex.Message, NotifyType.ErrorMessage);
    //}
}

Problem is that app doesn't see my file as Bitmap. When I try to get type of recived file it gives me System.__COMObject. I manage get file as storageitem, but I cannot read IRandomAccessStreamReference. As StorageItem I get, path, name etc.

The same thing is happening on ShareTarget example app, its also doesn't see image as BitMap(formatId). Any suggestions?

Refer this sample https://code.msdn.microsoft.com/How-to-share-data-between-6ef0a355 on msdn.

Target app:

if (operation.Data.Contains(StandardDataFormats.Bitmap))
{
    shareType.Text = "Bitmap";
    shareTitle.Text = operation.Data.Properties.Title;
    imgShareImage.Visibility = Visibility.Visible;
    tbShareData.Visibility = Visibility.Collapsed;
    RandomAccessStreamReference imageStreamRef = await operation.Data.GetBitmapAsync();
    IRandomAccessStreamWithContentType streamWithContentType = await imageStreamRef.OpenReadAsync();
    BitmapImage bitmapImage = new BitmapImage();
    bitmapImage.SetSource(streamWithContentType);
    imgShareImage.Source = bitmapImage;
}
