Then you should use, DataReader instead of Adapter.
1. Read the data using DataReader
2. Try Parse your date column to valid dates, if not possible alert to the user.

After a long struggle, i am able to find the answer of this mistery. There could be multiple reasons, but the most possible reason is to add 'IMEX=1' in connectionstring. Other possible reasons are.


Connection String: Provider=Microsoft.Jet.OLEDB.4.0;Data Source=FilePath;Extended Properties="Excel 8.0;HDR=Yes;IMEX=1";

1) "HDR=Yes;" indicates that the first row contains columnnames, not data. "HDR=No;" indicates the opposite.

2) "IMEX=1;" tells the driver to always read "intermixed" (numbers, dates, strings etc) data columns as text. Note that this option might affect excel sheet write access negative.

SQL syntax "SELECT * FROM [sheet1$]". I.e. excel worksheet name followed by a "$" and wrapped in "[" "]" brackets.

Important:

Check out the [HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Jet\4.0\Engines\Excel] located registry REG_DWORD "TypeGuessRows".

That's the key to not letting Excel use only the first 8 rows to guess the columns data type. Set this value to 0 to scan all rows. This might hurt performance.

If the Excel workbook is protected by a password, you cannot open it for data access, even by supplying the correct password with your connection string. If you try, you receive the following error message: "Could not decrypt file."
