Use your WriteableBitmap's clone and use this function as below:
使用您的 WriteableBitmap 的克隆并使用此函数，如下所示：
CreateThumbnail(filename, _frontBitmap.Clone());

void CreateThumbnail(string filename, BitmapSource image5)
{
if (filename != string.Empty)
{
using (FileStream stream5 = new FileStream(filename, FileMode.Create))
{
PngBitmapEncoder encoder5 = new PngBitmapEncoder();
encoder5.Frames.Add(BitmapFrame.Create(image5));
encoder5.Save(stream5);
}
}
}
