Just one thing: stop "converting" everything to string, and success will come to you. :-)

Solution 2

Dear Friend,

Rather applying

DateTime.ParseExact("YYYY-MM-DD",dr[3])

you should apply it as

DateTime.ParseExact(dr[3].ToString(),"YYYY-MM-DD",CultureInfo.InvariantCulture)

Please follow this link for more details:-

I hope this will help you out.

Thanks

Use DateTime.ToString("Format"); In order to get only the date.

Solution 3

Just use this..

If you are a real developer then you can do anything in programming..
It's too simple

<pre lang="c#">string s = "02/02/2012";
DateTime d = Convert.ToDateTime(s);</pre>

Accept my answer if you like it..
All the best.. :)

DateTime dt;
if(DateTime.TryParse(  Convert.ToString(dr[3]) ,out dt))
{
    cst.joiningdate = dt;
       
}

Solution 5

hi you can try this

DateTime dt = Convert.ToDateTime("02-12-12", System.Globalization.CultureInfo.CreateSpecificCulture("en-US").DateTimeFormat);

Note:
en-US is the datetime formate of us
if india
en-IN like this...........

Happy Coding!.......
