1.导出表格

代码 private void ToExcel(Control control, string fileName)
        {
            HttpContext.Current.Response.Buffer = true;
            HttpContext.Current.Response.Clear();
            HttpContext.Current.Response.Charset = "UTF-8";
            HttpContext.Current.Response.ContentEncoding = System.Text.Encoding.UTF8;
            HttpContext.Current.Response.ContentType = "application/ms-excel";
            //这里文件名称使用一下Url编码，防止中文导致的乱码问题
            HttpContext.Current.Response.AppendHeader("Content-Disposition", "attachment;filename=" + "" + System.Web.HttpUtility.UrlEncode(fileName, System.Text.Encoding.UTF8));
            TextWriter tw = HttpContext.Current.Response.Output;
            HtmlTextWriter htw = new HtmlTextWriter(tw);
            control.RenderControl(htw);
            HttpContext.Current.Response.End();
        }

2.导出文本

代码 private void ToTXT(string[] contents, string fileName)
        {
            HttpContext.Current.Response.Buffer = true;
            HttpContext.Current.Response.Clear();
            HttpContext.Current.Response.Charset = "UTF-8";
            HttpContext.Current.Response.ContentEncoding = System.Text.Encoding.UTF8;
            //和导出表格一样的道理,这里输出的内容类型修改下.
            HttpContext.Current.Response.ContentType = "application/ms-txt";
            HttpContext.Current.Response.AppendHeader("Content-Disposition", "attachment;filename=" + "" + System.Web.HttpUtility.UrlEncode(fileName, System.Text.Encoding.UTF8));
            TextWriter tw = HttpContext.Current.Response.Output;
            foreach (string str in contents)
                tw.WriteLine(str);
            HttpContext.Current.Response.End();
        }
