excel导出

第一种导出

     private void ExportExcel(DataTable exceldt)
        {
            string FileName = "";
            FileName = "投诉建议" + DateTime.Now.ToString("MMddHHmm");

            else if (bname.Contains("ie"))
            {
                FileName = HttpUtility.UrlEncode(FileName, System.Text.Encoding.UTF8);
            }
            else

            string colHeaders = "", ls_item = "";
            DataRow[] myRow = exceldt.Select();//可以类似dt.Select("id>10")之形式达到数据筛选目的
            int cl = exceldt.Columns.Count;
            for (int i = 0; i < 5; i++)
            {
                if (i == 0)

                else if (i == 4)
                {
                    colHeaders += "建议内容
";
                }
            }
            resp.Write(colHeaders);
            //向HTTP输出流中写入取得的数据信息 
            //逐行处理数据　　
            foreach (DataRow row in myRow)
            {
                //当前行数据写入HTTP输出流，并且置空ls_item以便下行数据　　 
                for (int i = 0; i < 5; i++)
                {
                    if (i == 0)
                    {
                        ls_item += row["name"] + "	";
                    }
                    else if (i == 1)
                    {
                        ls_item += row["account"] + "	";
                    }
                    else if (i == 2)
                    {

            }
            resp.End();
        }

                    path = Path.GetFullPath(path);

                    succeed = true;
                }
                catch (Exception ex)
