You can copy the C# code lines from the section below to create a PDF document from a web page or from an HTML string and save the resulting PDF to a memory buffer for further processing, to a PDF file or send it to the browser for download in ASP.NET applications.
C# Code Samples
To convert a HTML string or an URL to a PDF file you can use the C# code below.
// create the converter object in your code where you want to run conversion
HtmlToPdfConverter converter = new HtmlToPdfConverter();
// convert the HTML string to a PDF file
converter.ConvertHtmlToFile("<b>Hello World</b> from Winnovative !", null, "HtmlToFile.pdf");
// convert HTML page from URL to a PDF file
string htmlPageURL = "https://www.winnovative-software.com";
converter.ConvertUrlToFile(htmlPageURL, "UrlToFile.pdf");
To convert a HTML string or an URL to a PDF document in a memory buffer and then save it to a file you can use the C# code below.

HtmlToPdfConverter converter = new HtmlToPdfConverter();
// convert a HTML string to a memory buffer
byte[] htmlToPdfBuffer = converter.ConvertHtml("<b>Hello World</b> from Winnovative !", null);
// write the memory buffer to a PDF file
System.IO.File.WriteAllBytes("HtmlToMemory.pdf", htmlToPdfBuffer);
// convert an URL to a memory buffer
string htmlPageURL = "https://www.winnovative-software.com";
byte[] urlToPdfBuffer = converter.ConvertUrl(htmlPageURL);
