C#Excel上傳

前臺代碼：

    <div> 
        @using (Html.BeginForm("UploadOrderExcel", "Image", FormMethod.Post, new { enctype = "multipart/form-data" }))
        {
            <input type="file" id="file1" name="file1" />
            <input type="submit" name="Upload" value="上傳" />
        }
    </div>

controller代碼：

public ActionResult UploadWibllExcel()
        {
            ReturnJson ReJson = new ReturnJson();
            try
            {
                string FileName = DateTime.Now.ToString("yyyyMMddHHmmssfff");
                HttpPostedFileBase file = Request.Files["file2"];//獲取目標Excel
                string Url = Server.MapPath("~/");
                string filetype = file.FileName.Substring(file.FileName.LastIndexOf("."));
                file.SaveAs(Url + "/UploadFiles/" + FileName + filetype);
                string Path = Url + "/UploadFiles/" + FileName + filetype;
                Tools tools = new Tools();//自己定義的類
                tools.WibllFormE(Path);
                Response.Write("<script>alert('上傳成功')</script>");

            }
            catch (Exception ex)
            {
                Response.Write("<script>alert('上傳失敗')</script>");
                throw;
            }
            return null;
        }

Tool.cs

 public void WibllFormE(string FilePath)
        {
            DataTable excelDT = null;
            ExcelHelper excelhelper = new ExcelHelper(FilePath);
            excelDT = excelhelper.ExcelToDataTable("", true);
            string PersonInCharge = null;
            foreach (DataRow excelDR in excelDT.Rows)
            {
                PT_Waybill Mod = new PT_Waybill();//定義一個model
                Mod.Name= (string)excelDR["負責人"];//excelDR內爲Excel列名
                Mod.Describe = (string)excelDR["描述"];
                Mod.Type = (string)excelDR["貨物類型"];
                Mod.CargoCode = (string)excelDR["訂單號"];
                Mod.OrderNumber= (string)excelDR["運單號"];
                Mod.WaybillState = Convert.ToInt32((string)excelDR["運單狀態"]);
                Mod.GPName = (string)excelDR["省（發貨）"];
                Mod.GCName = (string)excelDR["市（發貨）"];
                GAName = (string)excelDR["縣區（發貨）"];
                Mod.GoodsAddress = (string)excelDR["詳細地址(發貨)"];
                Mod.GoodContact = (string)excelDR["聯繫方式（發貨）"];
                Mod.GoodUserName = (string)excelDR["聯繫人（發貨）"];
                Mod.EndTime = DateTime.FromOADate(Convert.ToDouble((string)excelDR["運單開始時間"]));
                Mod.AddTime = DateTime.FromOADate(Convert.ToDouble((string)excelDR["運單結束時間"]));
                WaybillService.Insert(Mod);
            }
        }

        ExcelToDateTable爲ExcelDBhelper下的方法，在我上一篇博客裏有。

        上傳時間出錯問題：將Excel內的時間格式轉換2018/1/1,然後單元格格式變爲文本格式，在使用上面代碼的DateTime.FromOADate()就行了。
