asp.net mvc - MVC4 - Uploading Image - Generic GDI+ Error -


i'm trying upload image , when try image.save(), "generic gdi+" error. great.

    // action handles form post , upload     [httppost]     public actionresult index(httppostedfilebase file, string filename)     {         // verify user selected file         if (file != null && file.contentlength > 0)         {                             string location = "~/content/images/specials/" + "rttest" + ".jpg";             bitmap bitmap = new bitmap(file.inputstream);             image image = (image)bitmap;             image.save(stream, system.drawing.imaging.imageformat.jpeg);             image.save(location);                     }         // redirect index action show form once again         return redirecttoaction("index");     }

the location of "~/content/images/specials/..." inaccessible gdi+ because isn't physical path. need use server.mappath() map virtual path physical path.

 string location = server.mappath("~/content/images/specials/" + "rttest" + ".jpg");

also, it's weird you're concatenating part of path, "rrest" ".jpg". may want before putting production aren't overwriting images on , over.
