I want to generate a PDF by passing HTML contents to a function. I have made use of iTextSharp for this but it does not perform well when it encounters tables and the layout
You can use Google Chrome print-to-pdf feature from its headless mode. I found this to be the simplest yet the most robust method.
var url = "https://stackoverflow.com/questions/564650/convert-html-to-pdf-in-net";
var chromePath = @"C:\Program Files (x86)\Google\Chrome\Application\chrome.exe";
var output = Path.Combine(Environment.CurrentDirectory, "printout.pdf");
using (var p = new Process())
{
p.StartInfo.FileName = chromePath;
p.StartInfo.Arguments = $"--headless --disable-gpu --print-to-pdf={output} {url}";
p.Start();
p.WaitForExit();
}
