在 nop 商务中获取图像 url 抛出异常
getting image url in nop commerce is throwing exception
我有以下异常：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;
}
}
就是不知道怎么解决。
有人知道怎么回事。
有关无效虚拟路径的问题。例外情况："is not a valid virtual path. at System.Web.Util.UrlPath.CheckValidVirtualPath(String path)"

好的，现在可以使用了。
使用 nopcommerce 图片模型，我可以生成这样的 base64 图片。
base64String = Convert.ToBase64String(picture.PictureBinary);
感谢您的帮助，希望这对其他人有帮助。
