            }
        }
        public void Completed(object sender WebBrowserDocumentCompletedEventArgs e)
        {
            //設置浏覽器寬度高度為文檔寬度高度以便截取整個網頁
            _webBrowserWidth = _webBrowserDocumentBodyScrollRectangleWidth;
            _webBrowserHeight = _webBrowserDocumentBodyScrollRectangleHeight;
            using (Bitmap bmp = new Bitmap(_webBrowserWidth _webBrowserHeight))
            {
                _webBrowserDrawToBitmap(bmp new Rectangle( bmpWidth bmpHeight));
                bmpSave("Capturepng" SystemDrawingImagingImageFormatPng);
                pictureBoxImageLocation = "Capturepng";
