C#导出GridView数据到Excel文件类实例

本文实例讲述了C#导出GridView数据到Excel文件类。分享给大家供大家参考。具体如下：

这段C#代码自定义了一个封装类，用于将GridView数据导出到Excel文件

using System;
using System.Web;
using System.Web.UI;
using System.IO;
using System.Web.UI.WebControls;
namespace DotNet.Utilities
{
  public class ExportExcel
  {
    protected void ExportData(string strContent, string FileName)
    {
      FileName = FileName + DateTime.Now.Year.ToString() + DateTime.Now.Month.ToString() + DateTime.Now.Day.ToString() + DateTime.Now.Hour.ToString() + DateTime.Now.Minute.ToString() + DateTime.Now.Second.ToString() + DateTime.Now.Millisecond.ToString();
      HttpContext.Current.Response.Clear();
      HttpContext.Current.Response.Charset = "gb2312";
      HttpContext.Current.Response.ContentType = "application/ms-excel";
      HttpContext.Current.Response.ContentEncoding = System.Text.Encoding.UTF8;
      //this.Page.EnableViewState = false;
      // 添加头信息，为"文件下载/另存为"对话框指定默认文件名
      HttpContext.Current.Response.AddHeader("Content-Disposition", "attachment; filename=" + FileName + ".xls");
      // 把文件流发送到客户端
      HttpContext.Current.Response.Write("");
      HttpContext.Current.Response.Write(strContent);
      HttpContext.Current.Response.Write("");
      // 停止页面的执行
      //Response.End();
    }
    /// 

    /// 导出Excel
    /// 
    /// 
    public void ExportData(GridView obj)
    {
      try
      {
        string style = "";
        if (obj.Rows.Count > 0)
        {
          style = @"
