Question

Response.Clear();
        Response.Buffer = true;
        Response.Charset = "utf-8";
        Response.AppendHeader("Content-Disposition", "attachment;filename=" + HttpUtility.UrlEncode("名称", System.Text.Encoding.UTF8) + ".xls");
        Response.ContentEncoding = System.Text.Encoding.GetEncoding("GB2312");     //设置输出流为简体中文
        Response.ContentType = "application/ms-excel";    //设置输出文件类型为excel文件。 
        this.EnableViewState = false;
        System.Globalization.CultureInfo myCItrad = new System.Globalization.CultureInfo("ZH-CN", true);
        System.IO.StringWriter oStringWriter = new System.IO.StringWriter(myCItrad);
        System.Web.UI.HtmlTextWriter oHtmlTextWriter = new System.Web.UI.HtmlTextWriter(oStringWriter);
