如何将ASP.NET WebAPI导入CSV文件操作改写成长尾关键词?

前端代码:

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;   } }
