这个是例子是网上淘来的，哈哈，很有用的！

首先要到网上下载itextsharp.dll，然后添加引用，主程序如下：

using System;
using System.Data;
using System.Configuration;
using System.Web;
using System.Web.Security;
using System.Web.UI;
using System.Web.UI.WebControls;
using System.Web.UI.WebControls.WebParts;
using System.Web.UI.HtmlControls;
using System.IO;
using iTextSharp;
using iTextSharp.text;
using iTextSharp.text.pdf;

public partial class _Default : System.Web.UI.Page 
{
    static DataTable datatable = new DataTable("testpdf");
    protected void Page_Load(object sender, EventArgs e)
    {
        if (!Page.IsPostBack)
        {
            DataRow dr;
            //建立Column例，可以指明例的类型,这里用的是默认的string
            datatable.Columns.Add(new DataColumn("编号"));
            datatable.Columns.Add(new DataColumn("用户名"));
            for (int i = 1; i < 5; i++)
            {
                dr = datatable.NewRow();
                dr[0] = System.Convert.ToString(i);
                dr[1] = "测试" + System.Convert.ToString(i);
                datatable.Rows.Add(dr);
            }
        }   
    }
    protected void Button1_Click(object sender, EventArgs e)
    {
        try
        {
            Document document = new Document();
            PdfWriter.GetInstance(document, new FileStream(Server.MapPath("Test.pdf"), FileMode.Create));
            document.Open();
            BaseFont bfChinese = BaseFont.CreateFont("C:\\WINDOWS\\Fonts\\simsun.ttc,1", BaseFont.IDENTITY_H, BaseFont.NOT_EMBEDDED);
            Font fontChinese = new Font(bfChinese, 12, Font.NORMAL,new Color(0, 0, 0)); 

            //按设置的字体输出文本
            document.Add(new Paragraph(this.TextBox1.Text.ToString(), fontChinese));
            //输出图片到PDF文件
            iTextSharp.text.Image jpeg01 = iTextSharp.text.Image.GetInstance(Server.MapPath("Images/gyl.jpg"));
            document.Add(jpeg01);
            iTextSharp.text.Image jpeg02 = iTextSharp.text.Image.GetInstance(Server.MapPath("Images/yy.jpg"));
            document.Add(jpeg02);

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

            for (int i = 0; i < datatable.Rows.Count; i++)
            {
                for (int j = 0; j < datatable.Columns.Count; j++)
                {
                    table.AddCell(new Phrase(datatable.Rows[i][j].ToString(), fontChinese));
                }
            }
            document.Add(table);

            document.Close();
            Response.Write("<script>alert('导出成功！');</script>");
        }
        catch (DocumentException de)
        {
            Response.Write(de.ToString());
        }
    }
}
