  if you want to save thumbimage in database then change 

  1. db.SP_EditUserInfo(data, e.Name, e.EmailID, e.PhoneNo, e.Address, e.ProfileImage);   

   to this

   

  1. db.SP_EditUserInfo(data, e.Name, e.EmailID, e.PhoneNo, e.Address, filename);

  You can use LEADTOOLS Imaging Pro SDK technology in your application. 
  https://www.leadtools.com/sdk/products/imaging-pro
  You can leverage the RasterCodecs class, which allows you to load any LEADTOOLS supported raster image format and export to any LEADTOOLS supported raster image format. You can utilize the RasterImageFormat enumeration and QualityFactor property, to indicate the image compression type and to specify the tradeoff between quality and compression.
  https://www.leadtools.com/help/sdk/v21/dh/to/compression-quality-factors.html

  I am unaware of the file format you are using, so the code below uses JPEG:

  // Load in source image
  using (RasterCodecs _codecs = new RasterCodecs())
  using (RasterImage _image = _codecs.Load(@"FILE PATH TO INPUT IMAGE"))
  {
      // QualityFactor takes values between 2 to 255
      // 2 being highest quality, 255 being most compression
      _codecs.Options.Jpeg.Save.QualityFactor = 100;
      _codecs.Save(_image, @"FILE PATH TO OUTPUT IMAGE", RasterImageFormat.Jpeg, 0);
  }

  copy paste and test

  1. public ActionResult DetailsEdit(EmployeeData___TBL e, string id, HttpPostedFileBase ImageFile)    
  2. {

  Thank You So Much Sachin Singh.

   

   

  How we find the image is resized or not ?

  why are you using postedFile when you are directly getting file, instead use this

  1. Stream strm = ImageFile.InputStream;

  Hi Salman,

   

   Here is my error

   

  'HttpPostedFile' does not contain a definition for 'PostedFile' and no accessible extension method 'PostedFile' accepting a first argument of type 'HttpPostedFileBase' could be found (are you missing a using directive or an assembly refernce?)

   

  Thanks in advance.
