上传Excel文件到数据库，但一些列为空

上传Excel文件到数据库有一个问题，我有一个字母数字值或只有数字值的列，当阅读第一行，如果有我的列中的数值，那么它只存储数字值通过表它不会select字母数字值，但如果它在第一行获得字母数字值，那么它将通过表格存储所有值

这是我的Excel工作表：

正如你可以在图片在TRAN DETAIL列中看到的，它很容易上传值到数据库，但是当有像在图像中标记的字母数字值时，它保存为空。

这是我的代码，我如何上传excel文件到数据库，

[HttpPost] public JsonResult UploadExcel(SBP_NEW users, HttpPostedFileBase FileUpload) { List<string> data = new List<string>(); if (FileUpload != null) { // tdata.ExecuteCommand("truncate table OtherCompanyAssets"); if (FileUpload.ContentType == "application/vnd.ms-excel" || FileUpload.ContentType == "application/vnd.openxmlformats-officedocument.spreadsheetml.sheet") { string filename = FileUpload.FileName; string targetpath = Server.MapPath("~/Doc/"); FileUpload.SaveAs(targetpath + filename); string pathToExcelFile = targetpath + filename; var connectionString = ""; if (filename.EndsWith(".xls")) { connectionString = string.Format("Provider=Microsoft.Jet.OLEDB.4.0; data source={0}; Extended Properties=Excel 8.0;", pathToExcelFile); } else if (filename.EndsWith(".xlsx")) { connectionString = string.Format("Provider=Microsoft.ACE.OLEDB.12.0;Data Source={0};Extended Properties=\"Excel 12.0 Xml;HDR=YES;IMEX=1\";", pathToExcelFile); } var adapter = new OleDbDataAdapter("SELECT * FROM [SBP OST Entries$]", connectionString); var ds = new DataSet(); adapter.Fill(ds, "ExcelTable"); DataTable dtable = ds.Tables["ExcelTable"]; string sheetName = "SBP OST Entries"; var excelFile = new ExcelQueryFactory(pathToExcelFile); var artistAlbums = from a in excelFile.Worksheet<SBP_NEW>(sheetName) select a; foreach (var a in artistAlbums) { try { if (a.SEQN_NUMB != "") { SBP_NEW TU = new SBP_NEW(); TU.SEQN_NUMB = a.SEQN_NUMB; TU.VALU_DATE = a.VALU_DATE; TU.DESCRIPTION = a.DESCRIPTION; TU.TRAN_DETAIL = a.TRAN_DETAIL; TU.TRAN_AMNT = a.TRAN_AMNT; TU.OTST_AMNT = a.OTST_AMNT; TU.BRAN_DEPT = a.BRAN_DEPT; TU.OUR_THEIR = a.OUR_THEIR; TU.REMARKS = a.REMARKS; TU.INST_NUMB = a.INST_NUMB; TU.TRAN_DATE = a.TRAN_DATE; TU.RECON_MODE = a.RECON_MODE; TU.USER_ID = a.USER_ID; TU.SUPR_RQRD = a.SUPR_RQRD; TU.SUPR_BY = a.SUPR_BY; TU.SUPR_DATE = a.SUPR_DATE; db.SBP_NEW.Add(TU); db.SaveChanges(); } else { //data.Add("<ul>"); //if (a.ID == 0 || a.ID == null) data.Add("<li> ID is required</li>"); //if (a.NAME == "" || a.NAME == null) data.Add("<li> Name is required</li>"); //data.Add("</ul>"); data.ToArray(); return Json(data, JsonRequestBehavior.AllowGet); } } catch (DbEntityValidationException ex) { foreach (var entityValidationErrors in ex.EntityValidationErrors) { foreach (var validationError in entityValidationErrors.ValidationErrors) { Response.Write("Property: " + validationError.PropertyName + " Error: " + validationError.ErrorMessage); } } } } //deleting excel file from folder if ((System.IO.File.Exists(pathToExcelFile))) { System.IO.File.Delete(pathToExcelFile); } return Json("success", JsonRequestBehavior.AllowGet); } else { //alert message for invalid file format data.Add("<ul>"); data.Add("<li>Only Excel file format is allowed</li>"); data.Add("</ul>"); data.ToArray(); return Json(data, JsonRequestBehavior.AllowGet); } } else { data.Add("<ul>"); if (FileUpload == null) data.Add("<li>Please choose Excel file</li>"); data.Add("</ul>"); data.ToArray(); return Json(data, JsonRequestBehavior.AllowGet); } }

当你input一个长整数时，将文本的concatinate (') ，然后转移到excel

例如，键入“1234567890123456789”，然后按ENTER键后将不会显示引号。
