Question

我需要使用c＃创建PDF文件。必须是我需要一个模板（例如，可编辑的PDF或HTML模板）。在此模板中，我必须插入文本和Picuture。

我不知道该怎么做。有人可以说我可以使用的技术吗？

Answer 1

您可以通过NuGet使用PdfSharp插件。只需创建html模板文件，将其读取为字符串，替换所需的内容，然后将完整的html传递给以下功能即可。

using TheArtOfDev.HtmlRenderer.PdfSharp;

    public static bool PdfSharpConvert(String html, string SaveTo)
    {
        try
        {
            using (var pdf = PdfGenerator.GeneratePdf(html, PdfSharp.PageSize.A4))
            {
                pdf.Save(SaveTo);
            }

            return true;
        }
        catch (Exception er)
        {
            return false;
        }
        finally
        {
            GC.Collect();
        }
    }

您可以使用iTextSharp.dll通过c＃程序创建PDF。借助此功能，您可以创建列表，项目符号要点，表格等。我已经在许多企业级应用程序中使用过它来创建PDF报表。

例如，创建以下文档您将需要以下代码：

Document doc = new Document(iTextSharp.text.PageSize.A4_LANDSCAPE, 25, 25, 43, 35);
            PdfWriter wri = PdfWriter.GetInstance(doc, new FileStream("C:\\test\\Updated_INVOICE#" + textBox45.Text + ".pdf", FileMode.Create));
            doc.Open();

            var myFont11 = FontFactory.GetFont("NewJune", 18, BaseColor.BLACK);
            var p1 = new Paragraph("AK TRAVEL GLOBAL LTD.\n", myFont11);
            doc.Add(p1);

            var AddFont = FontFactory.GetFont("NewJune", 8, BaseColor.BLACK);
            var p23 = new Paragraph("91 HIGH ST\nDUDLEY DY1 1QP\nPhone 01384 255777  Fax 08714 310690", AddFont);
            p23.Alignment = 23;
            doc.Add(p23);

            var myFont = FontFactory.GetFont("NewJune", 12, BaseColor.BLACK);
            var myFont1 = FontFactory.GetFont("NewJune", 30, BaseColor.GRAY);
            var p2 = new Paragraph("INVOICE\n\n", myFont1);
            p2.Alignment = 2;
            doc.Add(p2);

            var p3 = new Paragraph("INVOICE # " + textBox45.Text.ToString() + "\n", myFont);
            p3.Alignment = 2;
            doc.Add(p3);

            var p4 = new Paragraph("DATE: " + DateTime.Now.ToString(), myFont);
            p4.Alignment = 2;
            doc.Add(p4);

            var myFont12 = FontFactory.GetFont("NewJune", 26, BaseColor.BLACK);
            var pg1 = new Paragraph("BILL NUMBER - " + textBox45.Text, myFont12);
            pg1.Alignment = 1;
            doc.Add(pg1);

            PdfPTable table1 = new PdfPTable(2);
            table1.SpacingBefore = 50;

            var myFont111 = FontFactory.GetFont("NewJune", 25, BaseColor.BLACK);
            table1.AddCell(new PdfPCell(new Phrase("TO:", myFont111)));
            table1.AddCell(new PdfPCell(new Phrase("SHIP TO:", myFont111)));
            table1.AddCell(getCell("", PdfPCell.ALIGN_LEFT));
            table1.AddCell(getCell("", PdfPCell.ALIGN_RIGHT));
            table1.AddCell(getCell(textBox53.Text, PdfPCell.ALIGN_LEFT));
            table1.AddCell(getCell(textBox50.Text, PdfPCell.ALIGN_RIGHT));
            table1.AddCell(getCell(textBox52.Text, PdfPCell.ALIGN_LEFT));
            table1.AddCell(getCell(textBox49.Text, PdfPCell.ALIGN_RIGHT));
            table1.AddCell(getCell(textBox51.Text, PdfPCell.ALIGN_LEFT));
            table1.AddCell(getCell(textBox48.Text, PdfPCell.ALIGN_RIGHT));
            table1.AddCell(getCell("", PdfPCell.ALIGN_LEFT));
            table1.AddCell(getCell(textBox47.Text, PdfPCell.ALIGN_RIGHT));

            doc.Add(table1);

            PdfPTable table = new PdfPTable(6);
            table.SpacingBefore = 20;
