asp.net将GridView控件中的数据导出到Office(Excel,Word,PowerPoint)

代码如下:    #region 输出office
    private void Export(string Filetype, string FileName)
    {
        Response.Clear();
        Response.Buffer = true;
        Response.Charset = "GB2312";
        Response.AppendHeader("Content-Disposition", "attachment;filename=" + HttpUtility.UrlDecode(FileName, Encoding.UTF8).ToString());
        // 如果设置为 GetEncoding("GB2312");导出的文件将会出现乱码！！！
        Response.ContentEncoding = System.Text.Encoding.UTF7;
        Response.ContentType = Filetype;//设置输出文件类型。
        StringWriter oStringWriter = new StringWriter();
        HtmlTextWriter oHtmlTextWriter = new HtmlTextWriter(oStringWriter);
        gv.RenderControl(oHtmlTextWriter);
        Response.Output.Write(oStringWriter.ToString());
        Response.Flush();
        Response.End();
    }
    #endregion

    public override void VerifyRenderingInServerForm(Control control)
    {
        //base.VerifyRenderingInServerForm(control);
    }
