你应该试试：http: //itextpdf.com/

我有很多示例如何将其用于您描述的目的。

尝试这个，

您需要下载 wnvhtmlconvert.dll 才能使用 pdfconverter 类

--html端

  <table id="tbl" runat="server"  style="width: 940px;" cellpadding="0" cellspacing="0" border="0">
                <tr id="tr" runat="server">
                    <td id="td" runat="server" align="center" valign="top"></td>
                </tr>
            </table>

--代码端

 Imports System.Web.UI.WebControls
    Imports System.Web.UI.WebControls.WebParts
    Imports System.Web.UI.HtmlControls
    Imports System.IO
    Imports System.Collections.Generic
    Imports System.Drawing

    Public Sub ExportQuickScToPDF()
        Dim stringWrite As New System.IO.StringWriter()
        Dim htmlWrite As System.Web.UI.HtmlTextWriter = New HtmlTextWriter(stringWrite)
        Dim pdfByte As [Byte]() = Nothing
        Dim strPageBreak As String = "<br style=""page-break-before: always"" />"
        Dim lblPageBreak As New Label
        Dim lbltext As New Label
        lblPageBreak.Text = strPageBreak

        'add image 
        Dim imgqsc As New System.Web.UI.WebControls.Image
        imgqsc.ImageUrl = "path"
        td.Controls.Add(imgqsc)
        tbl.RenderControl(htmlWrite)
        'add text
        lbltext.Text = "text"
        lbltext.RenderControl(htmlWrite)
        'add page break
        lblPageBreak.Text = "text"
        lblPageBreak.RenderControl(htmlWrite)

        Dim objPdf As New PdfConverter()
objPdf.LicenseKey = "license key with dll"
        objPdf.PdfFooterOptions.ShowPageNumber = False
        objPdf.PdfFooterOptions.FooterTextFontSize = 10
        objPdf.PdfDocumentOptions.ShowHeader = True
        objPdf.PdfDocumentOptions.ShowFooter = False
        objPdf.PdfDocumentOptions.EmbedFonts = True
        objPdf.PdfDocumentOptions.LiveUrlsEnabled = True
        objPdf.RightToLeftEnabled = False
        objPdf.PdfSecurityOptions.CanPrint = True
        objPdf.PdfSecurityOptions.CanEditContent = True
        objPdf.PdfSecurityOptions.UserPassword = ""
        objPdf.PdfDocumentOptions.PdfPageOrientation = PDFPageOrientation.Landscape
        objPdf.PdfDocumentInfo.CreatedDate = DateTime.Now
        objPdf.PdfDocumentInfo.AuthorName = ""

        pdfByte = objPdf.GetPdfBytesFromHtmlString(stringWrite.ToString())

        Session("pdfByte") = pdfByte
    End Sub

您需要添加该 dll 的引用并将其导入代码中

您可以使用iTextSharp。还有一些其他的库。点击这里。

要创建 PDF，我使用“iText”库，它是开放的，并且非常易于使用。您可以在此处下载 iText 。

我也投票给 iText :) 开始时相当容易和舒适：

    string pdfFilename = @"c:\temp\test.pdf";
    string imageFilename = @"C:\map.jpg";

    // Create PDF writer, document and image to put
    iTextSharp.text.Image image = iTextSharp.text.Image.GetInstance(imageFilename);
    Document doc = new Document();
    PdfWriter pdfW = PdfWriter.GetInstance(doc, new FileStream(pdfFilename, FileMode.Create));

    // Open created PDF and insert image to it
    doc.Open();
    doc.Add(image);
    doc.Close();

尝试下载并添加 bytescout 的引用，然后使用以下代码：

using System.Diagnostics;
using Bytescout.PDF;

namespace WordSpacing
{
    /// <summary>
    /// This example demonstrates how to change the word spacing.
    /// </summary>
    class Program
    {
        static void Main()
        {
            // Create new document
            Document pdfDocument = new Document();
            pdfDocument.RegistrationName = "demo";
            pdfDocument.RegistrationKey = "demo";
            // Add page
            Page page = new Page(PaperFormat.A4);
            pdfDocument.Pages.Add(page);

            Canvas canvas = page.Canvas;

            Font font = new Font("Arial", 16);
            Brush brush = new SolidBrush();
            StringFormat stringFormat = new StringFormat();

            // Standard word spacing
            stringFormat.WordSpacing = 0.0f;
            canvas.DrawString("Standard word spacing 0.0", font, brush, 20, 20, stringFormat);

            // Increased word spacing
            stringFormat.WordSpacing = 5.0f;
            canvas.DrawString("Increased word spacing 5.0", font, brush, 20, 50, stringFormat);

            // Reduced word spacing
            stringFormat.WordSpacing = -2.5f;
            canvas.DrawString("Reduced word spacing -2.5", font, brush, 20, 80, stringFormat);


            // Save document to file
            pdfDocument.Save("result.pdf");

            // Cleanup 
            pdfDocument.Dispose();

            // Open document in default PDF viewer app
            Process.Start("result.pdf");
        }
    }
}

// 粘贴按钮点击

文档 pdfDoc = new Document(PageSize.A4, 25, 10, 25, 10);

            PdfWriter pdfWriter = PdfWriter.GetInstance(pdfDoc, Response.OutputStream);

            pdfDoc.Open();

            Paragraph Text = new Paragraph("This is test file"); // hardcode text

            pdfDoc.Add(new Phrase(this.lbl1.Text.Trim())); //from label

            pdfDoc.Add(new Phrase(this.txt1.Text.Trim())); //from textbox

            pdfDoc.Add(Text);

            pdfWriter.CloseStream = false;

            pdfDoc.Close();

            Response.Buffer = true;

            Response.ContentType = "application/pdf";

            Response.AddHeader("content-disposition", "attachment;filename=Example.pdf");
            Response.Cache.SetCacheability(HttpCacheability.NoCache);

            Response.Write(pdfDoc);

            Response.End();

首先获取参考，然后尝试使用此代码

using System.Runtime.InteropServices;
[DllImport("shell32.dll")]
public static extern int ShellExecute(int hWnd,
string lpszOp, string lpszFile, string lpszParams, string lpszDir,int FsShowCmd);
ShellExecute(0, "OPEN", args[0] + ".pdf", null, null, 0);

或者使用这个sharppdf或这个itextsharp
