100分求助，如何在ASP.NET2.0中把GridView中的数据导出到excel文件中？
哪位高手给解答下
重谢
[解决办法]
private void Export(string FileType, string FileName)
{//導出Excel
Response.Charset = "Big5";
Response.ContentEncoding = System.Text.Encoding.UTF7;
Response.AppendHeader("Content-Disposition", "attachment;filename=" + HttpUtility.UrlEncode(FileName, Encoding.UTF8).ToString());
Response.ContentType = FileType;
this.EnableViewState = false;
StringWriter tw = new StringWriter();
HtmlTextWriter hw = new HtmlTextWriter(tw);
GridView1.RenderControl(hw);
Response.Write(tw.ToString());
Response.End();
}
public override void VerifyRenderingInServerForm(Control control)
{
}
**.aspx页面中要加：EnableEventValidation = "false"
[解决办法]
使用CarlosAg.ExcelXmlWriter.dll第三方控件.
请参看:CarlosAg.ExcelXmlWriter实现.net下Excel导出功能（服务端不需要安装Excel程序）
