在Windows Phone应用中创建二维码扫描.

iam creating qr code scan in windows phone app.

using (IRandomAccessStream fileStream = await file.OpenAsync(FileAccessMode.Read))
{
     wrb = await Windows.UI.Xaml.Media.Imaging.BitmapFactory.New(1, 1).FromStream(fileStream);

它显示以下错误:

类型或名称空间名称'BitmapFactory'在 命名空间"Windows.UI.Xaml.Media.Imaging"(您是否缺少程序集 参考?)

The type or namespace name 'BitmapFactory' does not exist in the namespace 'Windows.UI.Xaml.Media.Imaging' (are you missing an assembly reference?)

您缺少WritableBitmapEx.WinRT.dll.它位于Sample Projects bin-> Debug Folder中.如果您的参考资料中已经列出了它，请将其删除并再次添加.这样就可以了！

You are missing the WritableBitmapEx.WinRT.dll. It is located in the Sample Projects bin -> Debug Folder. If it is already listed in your references delete it and add it again. Then it will work!
