asp.net 2.0 GridView导出数据到Excel

 在很多情况下，有可能要求把数据库中的数据导出成EXCEL格式的数据。在asp.net2。0中借助数据绑定控件GridView可以导出数据到EXCEL文件。这样就实现了数据格式多样化。
详细cs代码如下：

using System;
using System.Data;
using System.Configuration;
using System.Collections;
using System.Web;
using System.Web.Security;
using System.Web.UI;
using System.IO;
using System.Text;
using System.Web.UI.WebControls;
using System.Web.UI.WebControls.WebParts;
using System.Web.UI.HtmlControls;
using System.Data.SqlClient;

public partial class Security_ZHXXG_WebForms_XSBJXX_excel : System.Web.UI.Page
{
    protected void Page_Load(object sender, EventArgs e)
    {
        if (IsPostBack)
        {
            BindData();
        }
      

    }
    private void BindData()
    {
        SqlDataSource1.SelectCommand= "SELECT * FROM View_TS_XS_XSJBXX where bh='"+DropdownList_BJH1.SelectedValue+"'";
        GridView1.DataBind();
    }

这一段是必要的。。。
    public override void VerifyRenderingInServerForm(Control control)
    {
        // base.VerifyRenderingInServerForm(control);
    }
  

    protected void Button1_Click(object sender, EventArgs e)
    {
       
        GridView1.AllowPaging = false;
        Response.Clear();
        Response.Buffer = true;
        Response.Charset = "GB2312";
        Response.AppendHeader("Content-Disposition", "attachment;filename=XSJBXX.xls");
        Response.ContentEncoding = System.Text.Encoding.GetEncoding("GB2312");//设置输出流为简体中文
        Response.ContentType = "application/ms-excel";//设置输出文件类型为excel文件。
        this.EnableViewState = false;
        System.Globalization.CultureInfo myCItrad = new System.Globalization.CultureInfo("ZH-CN", true);
        System.IO.StringWriter oStringWriter = new System.IO.StringWriter(myCItrad);
        System.Web.UI.HtmlTextWriter oHtmlTextWriter = new System.Web.UI.HtmlTextWriter(oStringWriter);
        GridView1.RenderControl(oHtmlTextWriter);
        Response.Write(oStringWriter.ToString());
        Response.End();
           }
