一、前端代码
<button type="button" class="btn btn-primary" onclick="InportTicket()">导入</button> <input id="fileToUpload" type="file" name="upfile" style="display:none;">
/// JS脚本 $("#fileToUpload").click(); $("#fileToUpload").change(function () { var formData = new FormData(); formData.append("myfile", document.getElementById("fileToUpload").files[0]); $.ajax({ url: "../Ticket/TicketFileToUpload", type: 'POST', cache: false, processData: false, contentType: false, data: formData, success: function (res) { alert(res.Message); }, error: function (data, status, e) { alert("操作失败!"); } }) });
二、后台实现代码
[HttpPost] public ActionResult TicketFileToUpload() { try { if (Request.Files.Count > 0) { HttpPostedFileBase TicketFile = Request.Files[0]; List<string[]> lstData = Helper.ImportExport.InportData(TicketFile.InputStream); TicketModel ticketope = new TicketModel(); for (int i = 1; i < lstData.Count; i++) { string[] itemData = lstData[i]; Ticket entity = ticketope.GetByCode(itemData[0]); if (entity == null) { entity = new Ticket(); entity.Label = itemData[1]; entity.SiteId = int.Parse(itemData[2]); entity.Owner = itemData[4]; entity.CardId = itemData[5]; entity.StartDate = DateTime.Parse(itemData[6]); entity.EndDate = DateTime.Parse(itemData[7]); entity.IsValid = bool.Parse(itemData[8]); entity.IsUsed = bool.Parse(itemData[9]); ticketope.Insert(entity); } } return Json(new JsonResultData() { Success = true, Message = "导入数据成功!" }); } else { return Json(new JsonResultData() { Success = false, Message = "找不到导入文件数据!" }); } } catch (Exception ex) { return Json(new JsonResultData() { Success = false, Message = "导入数据失败!" }); } } public static List<string[]> InportData(Stream filestream) { lock (RunningInport) { List<string[]> lstData = new List<string[]>(); string strLine = ""; bool IsFirst = true; StreamReader sr = new StreamReader(filestream, Encoding.UTF8); while ((strLine = sr.ReadLine()) != null) { if (IsFirst) { string[] strTitles = strLine.Split(','); lstData.Add(strTitles); } else { string[] strData = strLine.Split(','); lstData.Add(strData); } } return lstData; } }
