  Save an image with a different name

  Jul 03, 2013 09:17 PM|engcanada|LINK

  I need to tottaly change the name of uploaded file but with its orginal extension.

  The following won't do:

  @{ WebImage photo = null;
  var newFileName = "";
  var imagePath = "";
  if(IsPost){
  photo = WebImage.GetImageFromRequest();
  if(photo != null){
  newFileName = Guid.NewGuid().ToString() + "_" + Path.GetFileName(photo.FileName);
  imagePath = @"images\" + newFileName;
  photo.Save(@"~\" + imagePath);
  }
  }
  }

  Path.GetExtension(photo.FileName);

  newFileName = Guid.NewGuid().ToString() + "_abcdefg" + Path.GetExtension(photo.FileName);

  Firstly, please show me as to how you would save the new file to a location?

  Are you aware that webmatrix upload helper picks the true extension of the actual file and not what has been specified in the Request.File

  That's why, if the extension of a file has been manually changed lets say from .jpg to .gif then Path.GetExtension(photo.FileName) woud be .gif But it really saves it with .jpg

  And then you would have a different name between what has been uploaded and what has been called in the database.

  Actually the code 

  photo.FileName

  Handles the name, so the extension is also provided in this! I mean if the file was 

  C:\Users\Afzaal\Pictures\Folder\profile pic.png

  Then the FileName will have the value as "profile pic.png"

  So writing the line as 

  Guid.NewGuid().ToString() + "_" + Path.GetFileName(photo.FileName);

  Will let you have the Image file name as: 45ea4527-7ddd-4965-b9ca-c6444982b342_profile pic.png

  
  If you don't get the required result, then there is a bug in your code, please check it twice!
