Hi,

This example retrieves a pdf document.

How can I save the data as a pdf file to disk?

Thanks

string jsonResponse ;

HttpWebRequest webRequest = (HttpWebRequest)WebRequest.Create(string uri);

webRequest.Method = "GET";

webRequest.Accept = "application/pdf";

using (HttpWebResponse webResponse = (HttpWebResponse)webRequest.GetResponse())

{

using (StreamReader reader = new StreamReader(webResponse.GetResponseStream()))

{

jsonResponse = reader.ReadToEnd();

}

You can take a stream and convert it to PDF using the DocumentConverter class. Here is an example that you can build on:

static void Main(string[] args)
{
   var outBytes = ConvertStreams(new MemoryStream(inBytes));
   File.WriteAllBytes("C:\Output\file.pdf", outBytes.ToArray());
}

static MemoryStream ConvertStreams(Stream inputStream)
{
   var ms = new MemoryStream(); //output stream
   using var document = DocumentFactory.LoadFromStream(inputStream, new LoadDocumentOptions());
   using var documentConverter = new DocumentConverter();
   var jobData = new DocumentConverterJobData
   {
      Document = document,
      DocumentFormat = DocumentFormat.Pdf,
      OutputDocumentStream = ms
   };

   var job = documentConverter.Jobs.CreateJob(jobData);
   documentConverter.Jobs.RunJob(job);

   if (job.Status == DocumentConverterJobStatus.Success)
      return ms;
   else
      return null;
}

Hi,

use below code --

 //Get the data from database into datatable     string strQuery = "select CustomerID, ContactName, City, PostalCode" +        " from customers";     SqlCommand cmd = new SqlCommand(strQuery);     DataTable dt = GetData(cmd);       //Create a dummy GridView     GridView GridView1 = new GridView();     GridView1.AllowPaging = false;     GridView1.DataSource = dt;     GridView1.DataBind();       Response.ContentType = "application/pdf";     Response.AddHeader("content-disposition",        "attachment;filename=DataTable.pdf");     Response.Cache.SetCacheability(HttpCacheability.NoCache);     StringWriter sw = new StringWriter();     HtmlTextWriter hw = new HtmlTextWriter(sw);     GridView1.RenderControl(hw);     StringReader sr = new StringReader(sw.ToString());     Document pdfDoc = new Document(PageSize.A4, 10f, 10f, 10f, 0f);     HTMLWorker htmlparser = new HTMLWorker(pdfDoc);     PdfWriter.GetInstance(pdfDoc, Response.OutputStream);     pdfDoc.Open();     htmlparser.Parse(sr);     pdfDoc.Close();     Response.Write(pdfDoc);     Response.End();   }

Hi,

Try this code :

HttpWebRequest webRequest = (HttpWebRequest)WebRequest.Create("");
webRequest.Method = "GET";
webRequest.Accept = "application/pdf";

using (HttpWebResponse webResponse = (HttpWebResponse)webRequest.GetResponse())
{
Stream objStream = webResponse.GetResponseStream();
using (var fileStream = new FileStream("Path To Save File", FileMode.Create, FileAccess.Write))
{
objStream.CopyTo(fileStream);
}
}
