Type cast in vb.net

[suganzeni]

Hi all when i trying to convert a string to date and store in data base
it shows type cast error

code is as follows:

dim s_date1 as string
dim s_date as date
s_date1 = s_mon & "/" & s_day & "/" & s_year
s_date = CType(s_date1, Date)

The Date type has a Parse method that will try to convert a string to a date:

dim s_date1 as string
dim s_date as date
s_date1 = s_mon & "/" & s_day & "/" & s_year
s_date = Date.Parse ( s_date1 )

HI
dim s_date1 as stringdim s_date as dates_date1 = s_mon & "/" & s_day & "/" & s_years_date = Date.Parse ( s_date1 )dim s_date1 as string
dim s_date as date
s_date1 = s_mon & "/" & s_day & "/" & s_year
s_date = Date.Parse ( s_date1 )

After i use the above code i got the following error

An unhandled exception of type 'System.FormatException' occurred in mscorlib.dll

Additional information: FormatException

also i tried with following types of type cast from string to date
s_date = Convert.ToDateTime(s_date1)
s_date = Date.ParseExact(s_date1, "mm/dd/yyyy", System.Globalization.DateTimeFormatInfo.InvariantInfo)
s_date = DateTime.Parse(s_date1)

Hi
I found whats the problem.
The format exception is because i have given it as
s_date1 = s_mon & "/" &s_day & "/" & s_year
But the system format is (dd/mm/yyyy)
so after giving as like follows
s_date1 = s_day & "/" & s_mon & "/" & s_year

All type casting form string to date is working.
s_date = CType(s_date1, Date)
s_date = Date.Parse(s_date1)
Its just a simple mistake.
Because of not clear about the date format of the system.
Any way thanks for your help NARUE

Right, the parse format is by default the system format. You can get around that incompatibility by constructing a date directly and then converting it to a date string with your desired format (if you need the string for anything else):

s_date = New Date ( s_year, s_mon, s_day )
s_date1 = s_date.ToString ( "MM/dd/yyyy" )
