WebAPI导入CSV
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;
}
}
