在nop commerce中获取图片网址会引发异常

我有以下例外： System.Web.HttpException （0x80004005）

这是导致它的代码 .

using (var img = System.Drawing.Image.FromFile(_pictureService.GetThumbLocalPath(picture)))
{
    using (var memStream = new MemoryStream())
    {
        img.Save(memStream, img.RawFormat);
        byte[] imageBytes = memStream.ToArray();

        // Convert byte[] to Base64 String
        base64String = Convert.ToBase64String(imageBytes);
        ImageBase64 = base64String;
    }
}

只是无法弄清楚如何解决它 .

任何人都知道了什么 .
