使用mvc 5上传到服务器时减小图像大小

Question

我有减少图像大小的代码，但我不明白如何将该图像保存到sql server数据库中，如果你有关于那个的逻辑那么请给我。 下面是我的服务器端代码，

 HttpPostedFileBase pphoto;   
string filename = Path.GetFileName(pphoto.FileName);
  string targetPath = Server.MapPath("Images/" + filename);
 Stream strm = pphoto.InputStream;
 var targetFile = targetPath;
//Based on scalefactor image size will vary
 /*generate thumbnales*/
  using (var image = Image.FromStream(strm))
{
var newWidth = (int)(image.Width * 0.5);
var newHeight = (int)(image.Height *0.5);    
var thumbnailImg = new Bitmap(newWidth, newHeight);
 var thumbGraph = Graphics.FromImage(thumbnailImg);
 var thumbGraph = Graphics.FromImage(thumbnailImg);
thumbGraph.CompositingQuality =CompositingQuality.HighQuality;
thumbGraph.SmoothingMode = SmoothingMode.HighQuality;
 thumbGraph.InterpolationMode = InterpolationMode.HighQualityBicubic;
 var imageRectangle = new Rectangle(0, 0,newWidth, newHeight);
 thumbGraph.DrawImage(image, imageRectangle);
 thumbnailImg.Save(targetPath, image.RawFormat);
}
