Commented Unassigned: Date issue with ExcelReaderFactory.CreateBinaryReader() [12993]

We are facing issue with date in .xls file.When we read the file using ExcelReaderFactory.CreateBinaryReader() all the dates availed in excel file converting to a number.

Dll version we are using is 2.1.2.0

How can we solve this issue any idea?

code we used :
public DataTable getDataTableOfExcel(Stream stream, string filename, bool IsFirstRowHasHeader)
{
try
{
IExcelDataReader excelReader = null;
FileInfo fileInfo = new FileInfo(filename);
if (fileInfo.Extension.ToLower().Equals(".xls"))
//1. Reading from a binary Excel file ('97-2003 format; *.xls)
excelReader = ExcelReaderFactory.CreateBinaryReader(stream);
else
//2. Reading from a OpenXml Excel file (2007 format; *.xlsx)
excelReader = ExcelReaderFactory.CreateOpenXmlReader(stream);

excelReader.IsFirstRowAsColumnNames = IsFirstRowHasHeader;
DataSet ds = excelReader.AsDataSet();
DataTable dt = ds.Tables[0].Copy();
return dt;
}
catch (Exception ex)
{
Logger.logError(logforimportrecipients, ex);
throw ex;
}
}

I think you can solve your problem by either

a) using the following method from ExcelReaderFactory to create the binary reader:

```
public static IExcelDataReader CreateBinaryReader(Stream fileStream, bool convertOADate)
```

with convertOADate set to true.

OR

b) retrieving the data set using method

```
/// <summary>
///Read all data in to DataSet and return it
/// </summary>
/// <param name="convertOADateTime">if set to <c>true</c> [try auto convert OA date time format].</param>
/// <returns>The DataSet</returns>
DataSet AsDataSet(bool convertOADateTime);
```

again with convertOADateTime set to true.
