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("<html><head><meta http-equiv=Content-Type content=\"text/html; charset=utf-8\">");
HttpContext.Current.Response.Write(strContent);
HttpContext.Current.Response.Write("</body></html>");
// 停止页面的执行
//Response.End();
}
/// <summary>
/// 导出Excel
/// </summary>
/// <param name="obj"></param>
public void ExportData(GridView obj)
{
try
{
string style = "";
if (obj.Rows.Count > 0)
{
style = @"<style> .text { mso-number-format:\@; } </script> ";
}
else
{
style = "no data.";
}
HttpContext.Current.Response.ClearContent();
DateTime dt = DateTime.Now;
string filename = dt.Year.ToString() + dt.Month.ToString() + dt.Day.ToString() + dt.Hour.ToString() + dt.Minute.ToString() + dt.Second.ToString();
HttpContext.Current.Response.AddHeader("content-disposition", "attachment; filename=ExportData" + filename + ".xls");
HttpContext.Current.Response.ContentType = "application/ms-excel";
HttpContext.Current.Response.Charset = "GB2312";
HttpContext.Current.Response.ContentEncoding = System.Text.Encoding.GetEncoding("GB2312");
StringWriter sw = new StringWriter();
HtmlTextWriter htw = new HtmlTextWriter(sw);
obj.RenderControl(htw);
HttpContext.Current.Response.Write(style);
HttpContext.Current.Response.Write(sw.ToString());
HttpContext.Current.Response.End();
}
catch
{
}
}
}
}
