利用xlst导出多表头的简便方法

　　大家都知道在ASP.NET中进行表格导出有很多种办法，aspose,npoi,cvs等等，今天就来介绍xlst,导出多表头。与以往不一样的是我们利用模板，只需要在模板中定义好表格样式，然后绑定数据就可以了。话不多说，直接上步骤

首先做模板，我们在excel把想导出的模板格式进行排版，举例(有的用户很可能看到过这个例子，我也是在园里看过来的，但是经过改良，有些不一样，先把原有地址贴过来：http://www.cnblogs.com/bluecountry/archive/2012/08/03/2622282.html)

然后我们将此文件保存为xml格式，最后用VS，也可以使用其它文档编辑工具打开，这时你会看到里面xml代码，然后编辑XML

在代码顶端加入xlst的头信息

<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">

<xsl:template>

.....

在文件末尾加上尾部信息，去掉多余的代码

</xsl:template>
</xsl:stylesheet>

最后将文件格式改为xlst这样，xlst文件就做好了，放到asp.net网站内，然后新建一个aspx页面，放置按钮用来触发导出excel事件，从后台从数据库获取数据，话不多说，直接上代码

首先是后台

  8 using System.Data.SqlClient;
  9 using System.Data;
 10 using System.Configuration;
 11 using System.IO;
 12 using System.Xml;

 14 namespace 导出测试
 15 {
 16     public partial class TJTest : System.Web.UI.Page
 17     {
 18         public readonly static string connString = ConfigurationManager.ConnectionStrings["DBBulkTest"].ToString();
 19         public SqlConnection connection = new SqlConnection(connString);
 20         public SqlConnection Connection
 21         {
 22             get
 23             {
 24                 if (connection == null)
 25                 {
 26                     connection = new SqlConnection(connString);
 27                 }
 28                 if (connection.State != ConnectionState.Open)
 29                 {
 30                     connection.Open();
 31                 }
 32                 return connection;
 33             }
 34         }
 35         protected void Page_Load(object sender, EventArgs e)
 36         {
 37 
 38         }
 39 
 40         protected void Button1_Click(object sender, EventArgs e)
 41         {
 42             //首先从数据库获取数据
 43             DataSet ds = new DataSet("ds");
 44             SqlDataAdapter da = new SqlDataAdapter("select ID,Area,jchs,jcje,syhs,syje,bghs,mark from tongji", Connection);
 45             SqlDataAdapter da1 = new SqlDataAdapter("select sum(jchs) jchs,sum(jcje) jcje,sum(syhs) syhs,sum(syje) syje,sum(bghs) bghs from tongji", Connection);
 46             da.Fill(ds, "tongji");
 47             da1.Fill(ds, "huizong");
 48 
 49             MemoryStream dataStream = new MemoryStream();
 50             ds.WriteXml(dataStream);//将数据读到内存流中
 51             dataStream.Position = 0;
 52             XmlReader reader = XmlReader.Create(dataStream);//创建xml读取器
 53             MemoryStream outStream = new MemoryStream();//声明内存流，用来存放转化后要输出的内容
 54 
 55             XslCompiledTransform xTrans = new XslCompiledTransform();
 56             xTrans.Load(Server.MapPath("~/wxjj.xlst")); //加载xlst模板文件
 57             xTrans.Transform(reader, null, outStream);//进行转化，并将得得到的内容放到outStream中
 58 
 59             outStream.Position = 0;
 60             StreamReader srHeader = null; //用来存放样式
 61             StreamReader srContent = null;//将内存流转为输出流
 62              try
 63             {
 64                 srContent = new StreamReader(outStream, System.Text.Encoding.UTF8);
 65                 //srHeader = new StreamReader(Server.MapPath("~/XlstHeader.txt"), System.Text.Encoding.UTF8);
 66                 this.Response.Clear();
 67                 string fileName = this.Server.UrlEncode("测试导出文件") + DateTime.Now.Date.ToString("yyyyMMdd") + ".xls";
 68                 this.Response.AppendHeader("Content-Disposition", "attachment;filename=" + fileName);
 69                 this.Response.ContentType = "application/vnd.ms-excel";
 70                 this.Response.ContentEncoding = System.Text.Encoding.UTF8;
 71                 this.Response.Charset = "gb2312";
 72                 //this.Response.Write(srHeader.ReadToEnd() + srContent.ReadToEnd() + "</Workbook>");
 73                 this.Response.Write(srContent.ReadToEnd());
 74                 this.Response.End();
 75             }
 76              catch (Exception ex)
 77              {
 78                  throw ex;
 79              }
 80              finally
 81              {
 82                  if (srContent != null)
 83                  {
 84                      try

后台代码

这里注意我在声明dataset与datatalbe的时候都命了名字，这在xlst模板绑定的时候会用到.接下来来看看我们的xlst文件代码

xlst 模板代码

在上面的xlst文件中，注意到<xsl:template match="ds">，<xsl:for-each select="tongji">，<xsl:for-each select="huizong">这几句话，再与后台代码中的

DataSet ds = new DataSet("ds");da.Fill(ds, "tongji");da1.Fill(ds, "huizong");进行对比，大家就知道绑定的原理了

导出结果，如下图

这里我没有给出数据表信息，主要目的是想让大家知道如何配置xslt以及后台如何使用模板
