这对我的作品：

[HttpGet]
public async Task<IActionResult> CreatePDF()
{
    var globalSettings = new GlobalSettings
    {
        ColorMode = ColorMode.Color,
        Orientation = Orientation.Portrait,
        PaperSize = PaperKind.A4,
        Margins = new MarginSettings { Top = 10 },
        DocumentTitle = "PDF Report",
    };

    var objectSettings = new ObjectSettings
    {
        PagesCount = true,
        HtmlContent = "<h>Hello World</h>",
        WebSettings = { DefaultEncoding = "utf-8"},
        HeaderSettings = { FontName = "Arial", FontSize = 9, Right = "Page [page] of [toPage]", Line = true },
        FooterSettings = { FontName = "Arial", FontSize = 9, Line = true, Center = "Report Footer" }
    };

    var pdf = new HtmlToPdfDocument()
    {
        GlobalSettings = globalSettings,
        Objects = { objectSettings }
    };

    var file = _converter.Convert(pdf);
    return File(file,"application/pdf");
}
