如何将数据从Excel表插入到asp.net中的数据表？

我想从Excel表插入数据到数据表，这工作正常。 但我不知道为什么我现在得到以下错误

“Microsoft Jet数据库引擎找不到”Sheet1“对象，请确保该对象存在，并且正确拼写其名称和path名称。

我的代码是检索数据是

if (fupExcel.HasFile) { // Get the name of the Excel spreadsheet to upload. string strFileName = Server.HtmlEncode(fupExcel.FileName); strAct = "New Schedule is uploaded, File name:" + strFileName; // Get the extension of the Excel spreadsheet. string strExtension = Path.GetExtension(strFileName); // Validate the file extension. if (strExtension != ".xls" && strExtension != ".xlsx") { ScriptManager.RegisterStartupScript(this, this.GetType(), "ntexl", "alert('Please select a Excel spreadsheet to import!');", true); return; } // Generate the file name to save. //string uploadFileName = DateTime.Now.ToString("yyyyMMddHHmmss") + strExtension; uploadFileName = CCMMUtility.GetCurrentDateTimeByTimeZone("US Mountain Standard Time").ToString("yyyyMMddHHmmss") + strExtension; // Save the Excel spreadsheet on server. fupExcel.UploadFile(uploadPath, uploadFileName); ClsScheduleFileNew objCLSSchedule = new ClsScheduleFileNew(); ClsScheduleFileNewProp objUserFile = new ClsScheduleFileNewProp(); objUserFile.FileName = strFileName; objUserFile.FilePath = uploadFileName; objUserFile.CreatedDate = CCMMUtility.GetCurrentDateTimeByTimeZone("US Mountain Standard Time"); //DateTime.Now; ScheduleFileId = objCLSSchedule.InsertFileInfo(objUserFile); hdfScheduleFileId.Value = ScheduleFileId.ToString(); if (ScheduleFileId != 0) { //ViewState["nw_Upload"] = ScheduleFileId; } else { ScriptManager.RegisterStartupScript(this, this.GetType(), "err", "alert('Some error occured while exporting the file.');", true); return; } // Generate the connection string for Excel file. strExcelConn = uploadPath; // There is no column name In a Excel spreadsheet. // So we specify "HDR=YES" in the connection string to use // the values in the first row as column names. if (strExtension == ".xls") { // Excel 97-2003 strExcelConn = "Provider=Microsoft.Jet.OLEDB.4.0;Data Source=" + strExcelConn + uploadFileName + ";Extended Properties='Excel 8.0;HDR=YES;'"; } else { // Excel 2007 strExcelConn = "Provider=Microsoft.ACE.OLEDB.12.0;Data Source=" + strExcelConn + uploadFileName + ";Extended Properties='Excel 12.0 Xml;HDR=YES;'"; } hdfStrExcelConn.Value = strExcelConn; try { ImportData(uploadFileName, uploadPath, strExcelConn, ScheduleFileId); } catch (Exception) { //Delete file over here and database entry over here. string path = uploadPath + uploadFileName; CCMMUtility.DeleteFilefromLocation(path); objCLSSchedule.DeleteScheduleFile(ScheduleFileId); ScriptManager.RegisterStartupScript(this, this.GetType(), "ntmtch", "alert('Some column values are not matched.');", true); return; } } 

Improt函数的代码是

  DataTable dt = new DataTable(); DataRow row; DataTable dtExcel = CreateDataTable(); using (OleDbConnection conn = new OleDbConnection(strConn)) { OleDbDataAdapter da = new OleDbDataAdapter("select * from [Sheet1]", conn); da.Fill(dt);// here i am getting that error // Create new datatable having non empty rows DataTable filteredDataTable = (dt.Rows.Cast<DataRow>().Where(t => t.ItemArray.Any(field => !(field is DBNull)))).CopyToDataTable<DataRow>(); // Fill the DataTable with data from the Excel spreadsheet. if (filteredDataTable.Rows.Count > 0) { // my code hete to fill datatable } 

Answer 1

尝试使用：

 "select * from [Sheet1$]" 

$是我需要的。

Answer 2

编写我尝试过的解决scheme。

将excel表单保存为一个逗号分隔的文件并保存为一个.txt文件

然后使用以下逻辑将其导入到数据表中。

  using (StreamReader sr = new StreamReader("C://File.txt")) { String line; int index = -1; while ((line = sr.ReadLine()) != null) { index++; iIndexofComma = line.IndexOf(@","); iLength = line.Length; dt.Rows.Add(); dt.Rows[index]["col1"] = line.Substring(0, iIndexofComma); dt.Rows[index]["col2"] = line.Substring(iIndexofComma + 1, iLength - iIndexofComma - 1); dtMapping.AcceptChanges(); } } 

希望有所帮助。
