c# - A generic error occurred in GDI+ when trying to save image -

i trying save webform image using code:

using system.drawing.printing; using system.drawing; using system.drawing.imaging;           protected void btntopdf_click(object sender, eventargs e)         {              capture("d://screenshot.jpg");//path save captured files          }          public static void capture(string capturedfilepath)         {             bitmap bitmap = new bitmap           (system.windows.forms.screen.primaryscreen.bounds.width, system.windows.forms.screen.primaryscreen.bounds.height);              graphics graphics = graphics.fromimage(bitmap system.drawing.image);             graphics.copyfromscreen(25, 25, 25, 25, bitmap.size);              bitmap.save(capturedfilepath, imageformat.jpeg);//error             bitmap.dispose();             graphics.dispose();          }   

i getting a generic error occurred in gdi+.

stacktrace

instead of saving directly bitmap path, try below:

 protected void page_load(object sender, eventargs e)     {         bitmap bmpscreenshot = screenshot();         bitmap bm;         byte[] ss = imagetobyte(bmpscreenshot);         using (var ms = new memorystream(ss))         {             bm = new bitmap(ms);             bm.save("d:\\test\\testimage.jpeg", imageformat.jpeg);         }      }     public static byte[] imagetobyte(system.drawing.image img)     {         imageconverter converter = new imageconverter();         return (byte[])converter.convertto(img, typeof(byte[]));     }     private bitmap screenshot()     {         bitmap bmpscreenshot =                 new bitmap(screen.primaryscreen.bounds.width, screen.primaryscreen.bounds.height);          using (var g = graphics.fromimage(bmpscreenshot))         {             g.copyfromscreen(0, 0, 0, 0, screen.primaryscreen.bounds.size);             return bmpscreenshot;         }      }
