Question

我这样做：

<FlipView x:Name="flipView"
              SelectionChanged="flipView_SelectionChanged">
        <FlipView.ItemTemplate>
            <DataTemplate>
                <Image Stretch="UniformToFill" Source="{Binding}" />
            </DataTemplate>
        </FlipView.ItemTemplate>
    </FlipView>

XAML

 await bitmapImage.SetSourceAsync(stream);

我得到了这个例外

发生了'System.Exception'类型的第一次机会异常   mscorlib.ni.dll

其他信息：找不到该组件。（例外   HRESULT：0x88982F50）

请问，问题是什么？

Answer 1

该程序有效，但问题是jpg文件损坏。它们的大小为0字节，因此无法创建stream。检查是否已创建此变量或是否已填充数据。
