I am routinely write code, but such problems:

Unable to read Excel (2003) in addition to the pure digital cell information!!

My code:
FileStream stream = File.Open(filePath, FileMode.Open, FileAccess.Read);
            IExcelDataReader excelReader;
            Regex r = new Regex(".xlsx");
            Match m = r.Match(filePath);
            if (m.Success)

                //2. Reading from a OpenXml Excel file (2007 format; *.xlsx)
                excelReader = ExcelReaderFactory.CreateOpenXmlReader(stream);
                //1. Reading from a binary Excel file ('97-2003 format; *.xls).
                excelReader = ExcelReaderFactory.CreateBinaryReader(stream);
            //3. DataSet - The result of each spreadsheet will be created in the result.Tables
            //DataSet result = excelReader.AsDataSet();
            //4. DataSet - Create column names from first row
            //excelReader.IsFirstRowAsColumnNames = true;
            DataSet ds = excelReader.AsDataSet();

            //5. Data Reader methods
            if (excelReader.Read())
                dgv_Data.DataSource = ds.Tables[1];

            //6. Free resources (IExcelDataReader is IDisposable)
Thanks advance!

I didn't quite understand what the problem was. Can you give me some more information? Maybe a stack trace if there is an exception?

the problem is that

when I import 2003excel file use CreateBinaryReader() and set (or not set) IsFirstRowAsColumnNames true,all can't show some special type of data in the excel

those data such as :x1,x2,x3,x4 (Numbers and letters with the format)

Can you create an issue and upload an example spreadsheet that exhibits this problem
