            PdfDocument doc = new PdfDocument();
            PdfSection section = doc.Sections.Add();
            PdfPageBase page = section.Pages.Add();
            PdfFont font = new PdfFont(PdfFontFamily.Helvetica, 11);
            PdfStringFormat format = new PdfStringFormat();
            format.LineSpacing = 20f;
            PdfBrush brush = PdfBrushes.Black;
            PdfTextWidget textWidget = new PdfTextWidget(text, font, brush);
            float y = 0;
            PdfTextLayout textLayout = new PdfTextLayout();
            textLayout.Break = PdfLayoutBreakType.FitPage;
            textLayout.Layout = PdfLayoutType.Paginate;
            RectangleF bounds = new RectangleF(new PointF(0, y), page.Canvas.ClientSize);
            textWidget.StringFormat = format;
            textWidget.Draw(page, bounds, textLayout);
            doc.SaveToFile("TxtToPDf.pdf", FileFormat.PDF);

Depending on what source you are using to generate the PDF, there is more than one way to do this. Consider using a professional toolkit like LEADTOOLS (https://www.leadtools.com/sdk/document/document-converter) which a number of classes and features that you can implement using server side ASP.NET.

For example, if your source is an image format and you want to save image PDF, you can use the following .NET code in a service:
RasterCodecs codecs = new RasterCodecs();

codecs.convert("input file", "output.pdf", RasterImageFormat.RasPdfJpeg411, 0, 0, 0, null);
If the source is a document such as Word or HTML, you can use the LEADTOOLS Document Converter to produce document PDF. The following code shows how the JavaScript Document Converter Control does that:
var url = "link to input file";

lt.Documents.DocumentFactory.loadFromUri(url, null)

   .done(function (document) {

      var jobData = new lt.Documents.DocumentConverterJobData();

      jobData.documentFormat = lt.Documents.Writers.DocumentFormat.user;

      jobData.rasterImageFormat = lt.Documents.RasterImageFormat.rasPdfJpeg;

      document.convert(jobData)

         .done(function (result) {

            var resultDocument = result.document != null ? result.document.url : result.archive.url;

            window.open(resultDocument);

         })

         .fail(function (jqXHR, statusText, errorThrown) {

            alert("Error converting document " + errorThrown);

         });

   })

   .fail(function (jqXHR, statusText, errorThrown) {

      alert("Error loading document " + errorThrown);

   });
