This method might be helpful - Convert HTML to PDF in C#

//Create a pdf document.
PdfDocument doc = new PdfDocument();
String url = "http://www.london2012.com/news/articles/paralympic-torch-relay-route-revealed-1258473.html";
Thread thread = new Thread(() =>
{ doc.LoadFromHTML(url, false, true, true);});
thread.SetApartmentState(ApartmentState.STA);
thread.Start();
thread.Join();
//Save pdf file.
doc.SaveToFile("sample.pdf");
doc.Close();
//Launching the Pdf file.
System.Diagnostics.Process.Start("sample.pdf");

This is the simplest way I know how you can create a PDF file via C# and additionally export that PDF directly to ASP.NET's client:
```
var document = DocumentModel.Load(Server.MapPath("~") + "\\files\\" + "hello.html");
document.Save(Response, "hello.pdf");
```
The code comes from this article about converting HTML file to a PDF file in C#.
There are other convertions available in the same manner, you can find additional information on supported file formats of this .NET's Word component overview page.

I am getting the following Error by using the code ....

int f = 0;

iTextSharp.text.pdf.PdfReader reader = new PdfReader(files[f]);

int n = reader.NumberOfPages;

iTextSharp.text.Document doc = new iTextSharp.text.Document(reader.GetPageSizeWithRotation(1));
iTextSharp.text.pdf.PdfWriter writer = iTextSharp.text.pdf.PdfWriter.GetInstance(doc, new FileStream(tempFolder + outputFile, FileMode.Create));

doc.Open();

PdfContentByte cb = writer.DirectContent;
PdfImportedPage page;
int rotation;

while (f < files.Length)
{
int i = 0;

while (i < n)
{
System.Math.Min(System.Threading.Interlocked.Increment(ref i), i - 1);

doc.SetPageSize(reader.GetPageSizeWithRotation(i));

doc.NewPage();

page = writer.GetImportedPage(reader, i);

rotation = reader.GetPageRotation(i);

if (rotation == 90 || rotation == 270)
cb.AddTemplate(page, 0, -1F, 1F, 0, 0, reader.GetPageSizeWithRotation(i).Height);
else
cb.AddTemplate(page, 1F, 0, 0, 1F, 0, 0);
}

System.Math.Min(System.Threading.Interlocked.Increment(ref f), f - 1);

if (f < files.Length)
{
reader = new PdfReader(files[f]);

n = reader.NumberOfPages;
}
}

doc.Close();


// reader = new PdfReader(tempFolder + outputFile);
PdfEncryptor.Encrypt(reader, new FileStream(outputFile, FileMode.Append), true, "test", "test", PdfWriter.AllowPrinting);



And Error is :
