.Net iTextSharp 导出pdf, 包含列表和图片

//引包iTextSharp，下载iTextSharp，项目引入itextsharp.dll

#region  一、数据列表

#region 数据列表标题

cell = new PdfPCell(new Phrase("姓名", ChFont_black));  //new Phrase("姓名"); 多个重载方法，可以添加样式等。
cell.Colspan = 1;  //默认为1；可以做合并单元格处理，列合并例如：cell.Colspan = 2 合并两列；行合并例如：cell.Rowspan = 2 合并两行
cell.BorderColor = new BaseColor(0, 0, 0); //单元格边框颜色，默认黑
4000
色
cell.BackgroundColor = new BaseColor(0, 102, 204); //单元格背景颜色
cell.HorizontalAlignment = Element.ALIGN_CENTER;  //水平居中
cell.VerticalAlignment = Element.ALIGN_MIDDLE;   //垂直居中
table.AddCell(cell);

cell = new PdfPCell(new Phrase("性别", ChFont_black));
cell.BackgroundColor = new BaseColor(0, 102, 204);
cell.HorizontalAlignment = Element.ALIGN_CENTER;
cell.VerticalAlignment = Element.ALIGN_MIDDLE;
table.AddCell(cell);

cell = new PdfPCell(new Phrase("年龄", ChFont_black));
cell.BackgroundColor = new BaseColor(0, 102, 204);
cell.HorizontalAlignment = Element.ALIGN_CENTER;
cell.VerticalAlignment = Element.ALIGN_MIDDLE;
table.AddCell(cell);

#region 列表数据

List<UserTest> userTestList = InitUserTestData(); //得到数据

foreach (UserTest info in userTestList)
{
//遍历数据后，第一列
cell = new PdfPCell(new Phrase(info.Name, ChFont_black));
cell.HorizontalAlignment = Element.ALIGN_CENTER;
cell.VerticalAlignment = Element.ALIGN_MIDDLE;
table.AddCell(cell);

//遍历数据后，第二列
cell = new PdfPCell(new Phrase(info.Sex, ChFont_black));
cell.HorizontalAlignment = Element.ALIGN_CENTER;
cell.VerticalAlignment = Element.ALIGN_MIDDLE;
table.AddCell(cell);

//遍历数据后，第三列
cell = new PdfPCell(new Phrase(info.Age, ChFont_black));
cell.HorizontalAlignment = Element.ALIGN_CENTER;
cell.VerticalAlignment = Element.ALIGN_MIDDLE;
table.AddCell(cell);
}

#endregion

//***cell.Table 可以进行table嵌套，适用于多个复杂table, 举例：外层嵌套框架table,  单元格内嵌套table,这样能够有效处理到处内容的结构。

#endregion

#region 二、嵌入图片

iTextSharp.text.Image img = iTextSharp.text.Image.GetInstance("E:\\wandapos\\02_Project\\14_Web\\03_WandaPOS\\WandaWebSite\\TempDoc\\209054a4-fa46-4882-8c2a-e9918ded954e.jpg"); //图片存放路径

cell = new PdfPCell();
cell.Colspan = 3;
cell.Image = img; //图片
cell.HorizontalAlignment = Element.ALIGN_LEFT;
cell.VerticalAlignment = Element.ALIGN_MIDDLE;
table.AddCell(cell);

#endregion

doc.Add(table); //将table元素添加入文档对象
doc.Close();
bytes = m.GetBuffer();
}
catch
{
//异常
}

ExportPDFFile("pdf名称", bytes);

}

//兼容MS/IE,FIREFOX浏览器处理
