I think this will work.

C#

ss = "Select * from tablename where expiredate>=#" & DateTimePicker1.Value.Date.ToString("MM/dd/yyyy") & "# and expiredate<=#" & DateTimePicker2.Value.Date.ToString("MM/dd/yyyy") & "# "

You should try and use Parameterised queries instead of concatenating strings. To compare between dates you can use the SQL Between functoin like this

C#

ss = "SELECT * FROM tablename WHERE expiredate BETWEEN @StartDate and @EndDate" 
yourCOmmand.Parameters.AddWithValue("@StartDate", DateTimePicker1.Value.Date);
yourCOmmand.Parameters.AddWithValue("@EndDate", DateTimePicker2.Value.Date);

If you are using Access database (you don't say) you might need to use the "?" parameter type instead of named paramters.

Hope this helps
