This maybe sounds "easy" but I haven't found a real solution. I need to create Pdf files from Html strings from an API on .Net Core. The library must be free (Not payments or anything related). I found that PDFSharp was a good option, but now I check out that PDFSharp is not available for .Net Core and It doesn't allow to inject a Html string.
So, PDFSharp is a good option for this case? Or what other library would you recommend me?
Thanks a lot.
I recently ran into the exact same issue myself. There is currently extremely limited ways in dealing with PDFs in general in .NET Core. To go through them...
IMO the only free one that will do what you need is SelectPDF. And that's saying something because I don't rate the library or the API. But it's free and it works.

if anyone needs an option with this, here is the final solution that I decided to use.
var url = "https://mcmap.net/q/48109/-convert-html-to-pdf-in-net-closed";
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();
}

Thanks @leonard-AB
Install NuGet package - Polybioz.HtmlRenderer.PdfSharp.Core https://www.nuget.org/packages/Polybioz.HtmlRenderer.PdfSharp.Core/1.0.0?_src=template
using PdfSharpCore;
using PdfSharpCore.Pdf;
using TheArtOfDev.HtmlRenderer.PdfSharp;
var document = new PdfDocument();
var html = "<html><body style='color:black'>PMKJ</body></html>";
PdfGenerator.AddPdfPages(document, html , PageSize.A4);
Byte[] res = null;
using (MemoryStream ms = new MemoryStream())
{
document.Save(ms);
res = ms.ToArray();
}
I run through this problem last few hours and found solution that work for me in .net6 C#.
install 3 library by Nugget:
here is my function:
[HttpPost]
public IActionResult PrintPDF([FromBody] string htmlString)
{
using (var ms = new MemoryStream())
{
// Parse the HTML
PdfDocument pdfx = PdfGenerator.GeneratePdf(htmlString, PageSize.A4);
pdfx.Save(ms);
//return File(ms, "application/pdf", "file.pdf");
var result = new FileContentResult(ms.ToArray(), "application/pdf");
result.FileDownloadName = "file.pdf";
return result;
}
}
I know this is an old question, but there are free .Net Core options, there are a few PDFSharp ports to Core, the one I use is
https://github.com/ststeiger/PdfSharpCore
It's being actively developed, at the point of writing this answer the update was 2 weeks ago.
It works well, only point to note is one of the libraries used does not have a very permissive licence,
https://github.com/ststeiger/PdfSharpCore/issues/285
But if you can work within the bounds of the licence then this is a good way to go with .Net Core, I am running a few projects on .Net7 with this package successfully.
