'String was not recognized as a valid DateTime

I am facing problem in the following situation:


I have a text box in the aspx file name: openDate. And my date format is mm/dd/yyyy.

C#:

private DateTime _opendate;

_openDate = DateTime.Parse(Request.Form["openDate"]);

I get error saying 'String was not recognized as a valid DateTime'

thanks in advance

Hi,

Just check what is the value you are getting from
Request.Form["openDate"].
I just works like this.

string date = "04/21/2005"; // in the format mm/dd/yyyy;
DateTime temp = DateTime.Parse(date);

//The above code runs without any exception.

Just check what the string are you getting using
Request.Form["open_date"];

Error occured when openDate query string is not in the date format
(mm/dd/yyyy).

Please use try, catch between your code lines.
And check whether the _opendate variable is null before using it.

private DateTime _opendate;


try
{
_opendate = DateTime.Parse(Request.Form["openDate"]);
}
catch(FormatException ex)
{
_opendate = null;
}

if(_opendate!=null)
{
//Do what ever you want
}

Hi Angrez:

I check it with your code but the same error message, but one thing
when i change the format "21/04/2005" means(dd/mm/yyyy) it is working.
Is that means my machine system date is setting is dd/mm/yyyy....?
then how do i know that which format of date could use by the client!

Thanks in advance

Hello,
Please try to use CurrentCulture's DateTimeFormat property.

DateTime dt = DateTime.Parse(dtString,
System.Threading.Tread.CurrentThread.CurrentCultur e.DateTimeFormat);

but obviously, it'll work only if dtstring is in correct format
according to Current DateTime format of your computer (or current
thread)

Hi Pial,
Instead of DateTime.Parser use Convert.ToDateTime(string date).
Hope that works for you.
