You can convert html to pdf in C#.NET using Aspose.PDF for ..NET API. You can find code samples on this page.

Hi, I hope I didn't misunderstood you, but if you are looking how to convert HTML to a PDF file in C# while located inside a default.aspx then try the following code:

protected void Button1_Click(object sender, EventArgs e)
{
    StringWriter sw = new StringWriter();
    HttpContext.Current.Server.Execute("~/invoice.aspx", sw);
            
    DocumentModel document;
    var option = new HtmlLoadOptions() { BaseAddress = this.Request.PhysicalApplicationPath };
    using (var htmlStream = new MemoryStream(option.Encoding.GetBytes(sw.ToString())))
        document = DocumentModel.Load(htmlStream, option);
 
    document.Save(this.Response, "Invoice.pdf");
}

So first you can use HttpServerUtility.Execute method and capture a string output from the executed handler. After retrieving a HTML formatted string of your invoice page you can create a PDF file in C# from it. For testing purposes the above code will export a PDF file in ASP.NET to the client's browser, but what you can do is save it to a stream and then use that stream when adding an attachment to an email.

Also in case I misunderstood you and you are actually looking to create a PDF while inside a invoice.aspx then just replace the code for retrieving a HTML formatted string with a following:

protected void Button1_Click(object sender, EventArgs e)
{
    StringWriter sw = new StringWriter();
    HtmlTextWriter hw = new HtmlTextWriter(sw);
    this.Page.RenderControl(hw);
 
    // ...

I'm guessing that you want to convert the rendered HTML file NOT the source HTML code. Correct? One thing to keep in mind here is that you should decide whether the PDF is going to be image based PDF (Each page consists of images only) or document based PDF (could include text and other objects). If you want to convert it to image based PDF, I once worked on something similar that lets you load the HTML file and render it. The way I did that by using a library called leadtools that took care of everything for me. If you want to convert the HTML page to document PDFs, this might need some Optical Character Recognition. Many libraries can enable you to perform OCR on the rendered HTML to extract the text and save the result PDF as image over text such as tesseract. Another approach is to use virtual printer driver, within your application you need to use a web control to print the page then capture the print job using the virtual printer and save the result to PDF.

Hi, please refer to this code,

using Spire.Pdf;
namespace htmltopdf
{
class Program
{
[STAThread]
static void Main(string[] args)
{
//Create a pdf document.
PdfDocument doc = new PdfDocument();
String url = "http://www.london2012.com/news/articles/paralympic-torch-relay-route-revealed-1258473.html";
doc.LoadFromHTML(url, false, true, true);

//Save pdf file.
doc.SaveToFile("sample.pdf");
doc.Close();
//Launching the Pdf file.
System.Diagnostics.Process.Start("sample.pdf");

}
}
}

you should use the third-party dll to finish converting html to pdf file in high quality.
