将GridView导入到Excel

前几天做项目需要用到将GridView中的数据导入到Excel，原以为很简单，上网搜了一下资料，果然方法不少，于是就采用了一个：

private void GridViewToExcel()
        {
           Response.Clear();
           Response.BufferOutput = true;
           //设定输出的字符集
           Response.Charset = "GB2312";

           //假定导出的文件名为FileName.xls
           Response.AppendHeader("Content-Disposition", "attachment;filename=FileName.xls");
           Response.ContentEncoding = System.Text.Encoding.GetEncoding("GB2312");
           //设置导出文件的格式
           Response.ContentType = "application/vnd.ms-excel";
           //关闭ViewState
           EnableViewState = false;
           System.Globalization.CultureInfo cultureInfo = new System.Globalization.CultureInfo("ZH-CN", true);
           System.IO.StringWriter stringWriter = new System.IO.StringWriter(cultureInfo);
           System.Web.UI.HtmlTextWriter textWriter = new System.Web.UI.HtmlTextWriter(stringWriter);
           GridView1.RenderControl(textWriter);
           //把HTML写回浏览器
           Response.Write(stringWriter.ToString());
           Response.End();
        }

引用此方法：

protected void btnToExcel_Click(object sender, EventArgs e)
        {
            //直接导出Excel
             GridViewToExcel();
        }

以上方法还不能真正实现功能，还需参考：
