converter.ConvertHtmlToFile("<b>Hello World</b> from Winnovative !", null, "HtmlToFile.pdf");

// convert HTML page from URL to a PDF file
string htmlPageURL = "http://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.

// create the converter object in your code where you want to run conversion
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 = "http://www.winnovative-software.com";
byte[] urlToPdfBuffer = converter.ConvertUrl(htmlPageURL);

// write the memory buffer to a PDF file
System.IO.File.WriteAllBytes("UrlToMemory.pdf", urlToPdfBuffer);

To convert in your ASP.NET MVC applications a HTML string or an URL to a PDF document in a memory buffer and then send it for download to browser 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 a HTML string to a memory buffer
byte[] htmlToPdfBuffer = converter.ConvertHtml("<b>Hello World</b> from Winnovative !", null);

FileResult fileResult = new FileContentResult(htmlToPdfBuffer, "application/pdf");
fileResult.FileDownloadName = "HtmlToPdf.pdf";
return fileResult;

To convert in your ASP.NET Web Forms application a HTML string to a PDF document in a memory buffer and then send it for download to browser you can use the C# code below.
