1.前端：

放置瀏覽按鈕

        <div class="row inner_table text-center">
            <input id="fileId" type="file" name="fileString"  class="file ">  
        </div>

2. JS：

註冊瀏覽按鈕的事件

var ChoseFile = function () {
    $("input[name=fileString]")
        .change(function () {
            var
 
 filePath = $("[name=‘fileString‘]");
            //讀取文件內容
            var formData = new FormData();
            formData.append(‘file[]‘, filePath[0].files[0]);
   
            $.ajax({
                url:  "XXXXXXXX入庫鏈接",
                type: ‘POST‘,
                data: formData,
                async: 
 
false,
                cache: false,
                contentType: false,
                processData: false,
                success: function (returndata) {
                   alert("上傳成功");
                },
                error: function (returndata) {
                   alert("上傳失敗");
                }
            });

        });
}
 

3 controller:

[CustomAuthorize(AuthType.Authrozied)]
        public JsonResult DataImport(FormCollection form)
        {
            string zipDir = Path.Combine(AppDomain.CurrentDomain.BaseDirectory, "templateFiles");
            string masterFile = Path.Combine(zipDir, "template" + ".csv");
            if (!Directory.Exists(zipDir))
            {
                Directory.CreateDirectory(zipDir);
            }
            var file = Request.Files[0];
　　　　　　　//上傳
            file.SaveAs(masterFile);
            DataTable dt = GetCSVToData(masterFile);
            List<ScheduleTableInfo> infos = new List<ScheduleTableInfo>();
            foreach (DataRow dataRow in dt.Rows)
            {
                ScheduleTableInfo info = new ScheduleTableInfo();
                info.TemplateName = dataRow["標題名1"].ToString();
                info.SumLevelName = dataRow["標題名2"].ToString();
                infos.Add(info);
            }
            //執行入庫操作
            int value = _client.ImportData(infos);

            var jsonStr = JsonConvert.SerializeObject(infos, new DataTableConverter(),
                new JavaScriptDateTimeConverter());
            jsonStr = jsonStr.Replace("\\\\n", "\\r");


            var result = Json(jsonStr, JsonRequestBehavior.AllowGet);
            return result;
        }

功能子函數：

        private DataTable GetCSVToData(string strCsvPath, bool hasHeader = true, bool needLineNo = false)
        {
            CSVReader csvReader = null;
            try
            {
                csvReader = new CSVReader(strCsvPath, FileEncoding.GetType(strCsvPath));
                DataTable dt = csvReader.GetTable(1, -1, hasHeader);
                return dt;
            }
            catch (Exception ex)
            {
                LogService.Debug("解析csv文件錯誤：" + ex);
                return null;
            }
            finally
            {
                if (csvReader != null)
                {
                    csvReader.Dispose();
                }
            }
        }

導入文件，獲取文件位置

.NET 上傳並解析CSV文件存庫
