Question

我正在将Excel（.xls）工作表导出到数据集。在那个excel我有16列。在导出时，我收到的错误是“TOO MANY FIELDS DEFINED”..

这是我的代码部分..

{
            string strFilePathOnServer = ConfigurationManager.AppSettings["RevenueDumpFileLocation"];
            String sConnectionString = @"Provider=Microsoft.Jet.OLEDB.4.0;Data Source=" + Server.MapPath(strFilePathOnServer) + RevenueDumpFileUpload.FileName + ";Extended Properties=\"Excel 8.0;IMEX=1;HDR=NO;TypeGuessRows=0;ImportMixedTypes=Text\"";

            string strPostedFileName = RevenueDumpFileUpload.PostedFile.FileName;
            if (strPostedFileName != string.Empty && RevenueDumpFileUpload.PostedFile.ContentLength != 0)
            {

                RevenueDumpFileUpload.PostedFile.SaveAs(Server.MapPath(strFilePathOnServer) + RevenueDumpFileUpload.FileName);
                RevenueDumpFileUpload.FileContent.Dispose();
            }

            OleDbConnection Exlcon = new OleDbConnection(sConnectionString);
            try
            {
                //Exlcon.Open();
            }
            catch
            {
                return;
            }
            OleDbCommand objCmdSelect = new OleDbCommand("SELECT * FROM [Owner$]", Exlcon);
            OleDbDataAdapter objAdapter1 = new OleDbDataAdapter();
            objAdapter1.SelectCommand = objCmdSelect;
            objDataset1.Clear();
            objAdapter1.Fill(objDataset1, "XLData");

当越过Fill方法时，我收到错误...

如何解决这个问题......

将列限制为仅250

string sql = "select * from [A1:IU]";

将Excel导出到数据集（错误 - 定义太多字段）
