突然之前显示的图片停止显示在页面上并检查文件夹 * 发现当我单击它们时图像不显示。调试我的代码,我发现注释行导致了它。下面的代码是否无论如何都在操纵流?

public ActionResult UploadPhoto(UserPhotoUploadModel photoFileModel)
{
        HttpPostedFileBase photoFile = photoFileModel.PhotoFile;
    string uploadPath = Server.MapPath("~/Content/users/photos");
    string autoFileName = String.Format("{0}_{1}", Guid.NewGuid().ToString(), filename);
    string fileDestName = Path.Combine(uploadPath, autoFileName);

    //Starting from here is where the issue lies
    Stream imgStream = photoFile.InputStream;
    using (imgStream)
    {
        Image img = Bitmap.FromStream(imgStream);
        int width = img.Width;
        int height = img.Height;

        if (width > 100 || height > 100)
        {
            ModelState.AddModelError("PhotoFile", "Photo dimension should be 100 by 100 or less");
            return View(photoFileModel);
        }
    }
    //the issue ends here

    photoFile.SaveAs(fileDestName);

    return RedirectToAction("Profile", new {id = loggedinUser.ProviderUserKey});
}

保存的文件具有正确的图像扩展名,例如 JPG。我正在使用流来确定上传图像的尺寸。

注释部分是导致此问题的原因。如何在输入流完好无损的情况下做到这一点?

谢谢。

问题是这一行:

 return View(photoFileModel);

当代码到达这一行时,它会退出该方法。因此,不执行此行:

photoFile.SaveAs(fileDestName);
