Generate PDF from aspx page


I am developing a code based on the sample code given by you. The code is as follows.

string WebUrl = HttpContext.Current.Request.Url.ToString(); // http://localhost:8080/sales.aspx

HttpWebRequest request = (HttpWebRequest)WebRequest.Create(WebUrl);

request.Timeout = 10000; // 10 secs

HttpWebResponse localWebResponse = (HttpWebResponse)request.GetResponse();

Encoding encoding = Encoding.GetEncoding(1252);

StreamReader localResponseStream = new StreamReader(localWebResponse.GetResponseStream(), encoding);

Aspose.Pdf.Generator.Pdf pdf = new Aspose.Pdf.Generator.Pdf();

Aspose.Pdf.Generator.Section section = pdf.Sections.Add();

Aspose.Pdf.Generator.Text text = new Aspose.Pdf.Generator.Text(section, localResponseStream.ReadToEnd());

text.IsHtmlTagSupported = true;


pdf.HtmlInfo.ImgUrl = “Images”;




It always throwing the errors at pdf.Save. The error is object reference not set to instance of an object.

An early reply with working code is highly appreciated.

I tried your sample code and it works fine. Please share your aspx file (or create a sample application and upload here) . This will help us reproduce the issue and get back to you soon.

Thank You & Best Regards,
