C#调用iTextSharp组件生成PDF文件

2009-08-22 09:57 465 查看

项目中一般的导出文件都是导出到Excel中，最新在项目中又要求将查询的报表结果导出成PDF文件。这只是一个开篇的小例子，继续研究中...

后台代码：

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 iTextSharp;
using iTextSharp.text;
using iTextSharp.text.pdf;
using System.IO;

public partial class _Default : System.Web.UI.Page
{
static DataTable datatable = new DataTable("test01pdf");

protected void Page_Load(object sender, EventArgs e)
{
//判断是否是回发页面
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"));
datatable.Columns.Add(new DataColumn("年龄"));
datatable.Columns.Add(new DataColumn("性别"));
for (int i = 1; i < 100; i++)
{
dr = datatable.NewRow();
dr[0] = System.Convert.ToString(i);
dr[1] = "go158" + System.Convert.ToString(i);
dr[2] = "21";
dr[3] = "男孩";
datatable.Rows.Add(dr);
}
}

}
protected void Button1_Click(object sender, EventArgs e)
{

try
{
Document document = new Document();

PdfWriter.GetInstance(document, new FileStream(Server.MapPath("Chap0106.pdf"),FileMode.Create));

document.Open();
BaseFont bfChinese = BaseFont.CreateFont("C://WINNT//Fonts//SIMSUN.ttc,1", BaseFont.IDENTITY_H, BaseFont.NOT_EMBEDDED);
Font fontChinese = new Font(bfChinese, 12, Font.NORMAL,new Color(0, 0, 0));
document.Add(new Paragraph(this.TextBox1.Text.ToString(), fontChinese));

// document.AddTitle("测试数据PDF");
iTextSharp.text.Image jpeg = iTextSharp.text.Image.GetInstance(Server.MapPath("portal2.jpg"));
document.Add(jpeg);

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();
}
catch (DocumentException de)
{
Response.Write(de.ToString());
}
}
}
