原文 [ASP.NET]利用itextsharp将GridView汇出PDF档
最近在讨论区看到有人说itextsharp可以把网页变成PDF
小弟就去抓一下itextsharp来玩玩,先教大家最实用的,就是把GridView汇出成PDF档
asp.net(c#)
<%@ Page Language="C#" AutoEventWireup="true" CodeBehind="Index.aspx.cs" Inherits="GridViewToPDF.Index" %>
<!DOCTYPE html>
<html xmlns="http://www.w3.org/1999/xhtml">
<head runat="server">
<title>GridViewToPDF</title>
</head>
<body>
<form id="form1" runat="server">
<div>
<asp:Button ID="Button1" runat="server" OnClick="Button1_Click" Text="汇出至PDF档" />
<asp:GridView ID="GridView1" runat="server">
</asp:GridView>
</div>
</form>
</body>
</html>
using System;
using iTextSharp.text;
using iTextSharp.text.pdf;
using iTextSharp.text.html.simpleparser;
using System.IO;
using System.Web;
using System.Web.UI;
using System.Web.UI.HtmlControls;
using System.Collections.Generic;
namespace GridViewToPDF
{
public partial class Index : System.Web.UI.Page
{
protected void Page_Load(object sender, EventArgs e)
{
if (!IsPostBack)
{
List<member> mem = new List<member>();
mem.Add(new member("1", "Puma"));
mem.Add(new member("2", "F6 Team"));
this.GridView1.DataSource = mem;
this.GridView1.DataBind();
}
}
protected void Button1_Click(object sender, EventArgs e)
{
Response.ContentType = "application/pdf";
Response.ContentEncoding = System.Text.Encoding.UTF8;
Response.AddHeader("content-disposition", "attachment;filename=test.pdf");
Response.Cache.SetCacheability(HttpCacheability.NoCache);
System.IO.StringWriter stringWrite = new StringWriter();
System.Web.UI.HtmlTextWriter htmlWrite = new HtmlTextWriter(stringWrite);
HtmlForm form = new HtmlForm();
form.Controls.Add(GridView1);
form.Controls[0].RenderControl(htmlWrite);
StringReader reader = new StringReader(stringWrite.ToString());
Document doc = new Document(PageSize.A4);
HTMLWorker parser = new HTMLWorker(doc);
PdfWriter.GetInstance(doc, Response.OutputStream);
doc.Open();
parser.Parse(reader);
doc.Close();
}
}
public class member
{
private string _id;
private string _name;
public member(string ID, string Name)
{
_id = ID;
_name = Name;
}
public string ID
{
set { _id = value; }
get { return _id; }
}
public string Name
{
set { _name = value; }
get { return _name; }
}
}
}
执行结果：
