首先要到网上下载itextsharp.dll，然后添加引用，主程序如下：

using System; 

02
using System.Data; 

03
using System.Configuration; 

04
using System.Web; 

05
using System.Web.Security; 

06
using System.Web.UI; 

07
using System.Web.UI.WebControls;

using System.Web.UI.WebControls.WebParts; 

09
using System.Web.UI.HtmlControls; 

10
using System.IO; 

11
using iTextSharp; 

12
using iTextSharp.text; 

13
using iTextSharp.text.pdf; 

14
  
15
public partial class _Default : System.Web.UI.Page  

16
{ 

17
    static DataTable datatable = new DataTable("testpdf"); 

18
    protected void Page_Load(object sender, EventArgs e) 

19
    { 

20
        if (!Page.IsPostBack) 

21
        { 

22
            DataRow dr; 

23
            //建立Column例，可以指明例的类型,这里用的是默认的string 

24
            datatable.Columns.Add(new DataColumn("编号")); 

25
            datatable.Columns.Add(new DataColumn("用户名")); 

26
            for (int i = 1; i < 5; i++) 

27
            { 

28
                dr = datatable.NewRow(); 

29
                dr[0] = System.Convert.ToString(i); 

30
                dr[1] = "测试" + System.Convert.ToString(i); 

31
                datatable.Rows.Add(dr); 

32
            } 

33
        }    

34
    } 

35
    protected void Button1_Click(object sender, EventArgs e) 

36
    { 

37
        try

38
        { 

39
            Document document = new Document(); 

40
            PdfWriter.GetInstance(document, new FileStream(Server.MapPath("Test.pdf"), FileMode.Create)); 

41
            document.Open(); 

42
            BaseFont bfChinese = BaseFont.CreateFont("C:\\WINDOWS\\Fonts\\simsun.ttc,1", BaseFont.IDENTITY_H, BaseFont.NOT_EMBEDDED); 

43
            Font fontChinese = new Font(bfChinese, 12, Font.NORMAL,new Color(0, 0, 0));  

44
  
45
            //按设置的字体输出文本 

46
            document.Add(new Paragraph(this.TextBox1.Text.ToString(), fontChinese)); 

47
            //输出图片到PDF文件 

48
            iTextSharp.text.Image jpeg01 = iTextSharp.text.Image.GetInstance(Server.MapPath("Images/gyl.jpg")); 

49
            document.Add(jpeg01); 

50
            iTextSharp.text.Image jpeg02 = iTextSharp.text.Image.GetInstance(Server.MapPath("Images/yy.jpg")); 

51
            document.Add(jpeg02); 

52
  
53
            PdfPTable table = new PdfPTable(datatable.Columns.Count); 

54
  
55
            for (int i = 0; i < datatable.Rows.Count; i++) 

56
            { 

57
                for (int j = 0; j < datatable.Columns.Count; j++) 

58
                { 

59
                    table.AddCell(new Phrase(datatable.Rows[i][j].ToString(), fontChinese)); 

60
                } 

61
            } 

62
            document.Add(table); 

63
  
64
            document.Close(); 

65
            Response.Write("<script>alert('导出成功！');</script>"); 

66
        } 

67
        catch (DocumentException de) 

68
        { 

69
            Response.Write(de.ToString()); 

70
        }
