How to convert HTML C# code to pdf, using api2pdf/htmlagilitypack

Question

I'm trying to convert HTML code written in C# to a PDF but getting issues when trying to do so. I get an error that says cannot HTMLAgilityPack.HTMLDocument object to Api2PdfChromeHtmltoPDFRequest. Is there a way to do so with these 2 libraries, or any better solutions?

var html = String.Format(@"<!DOCTYPE html>
<html><h1> Hello world </h1> </html>");

var doc = new HtmlDocument();
doc.LoadHtml(html)

Api2Pdf.Api2PdfResult emailConversionResult = a2pClient.Chrome.HtmlToPdf(doc);

According to the documentation, HtmlToPdf is expecting an ChromeHtmlToPdfRequest object (https://github.com/Api2Pdf/api2pdf.dotnet/blob/ba7da6496a45e1e07627158bc76d9ea48cdc6255/Api2Pdf.DotNet/RequestModels.cs#L42)

This is also what the error is trying to tell you. You are passing in an object of type HTMLAgilityPack.HTMLDocument, yet the HtmlToPdf method is expecting an object of type ChromeHtmlToPdfRequest. The compiler then complains that it cannot convert the first to the latter and throws an error at you.

So your code should look like this:

var emailConversionResult = a2pClient.Chrome.HtmlToPdf(new ChromeHtmlToPdfRequest
{
     Html = html
});

Html here is a string. So if you must use HtmlAgilityPack for some reason, you can also use this snippet:

var emailConversionResult = a2pClient.Chrome.HtmlToPdf(new ChromeHtmlToPdfRequest
{
     Html = doc.DocumentNode.OuterHtml
});
