[C# Programming]

End Google Ads 201810 - BS.net 01 --> Dear all
am new to c#(2008).

i created a stored procedure in sql server 2000.

"select * from employee where joindate between @d1 and @d1"

I was using Table Adapter fill,get methods.

when i tried to pass the date value which in "MM/dd/yyyy"

it raises error message invalid datetime,then

i declared DateTime variable and use Datetime.Parse(date in "MM/dd/yyyy"),
DateTime.Parseexact,error not a valid datetime. i use Culture info ("en-US"),but no luck.
