Answer 1

Yes, if you know the format and you use (Try)ParseExact, then it doesn't matter about the culture:

      string s = "20110714";

      string f = "yyyyMMdd";

      DateTime dt;

      bool isValid = DateTime.TryParseExact(s, f, null, 0, out dt);

      if (isValid)

      {

         Console.WriteLine(dt);

      }

hi,

use this:

string @DOB = DateTime.ParseExact(txtDOB.Text, "dd/MM/yyyy", System.Globalization.CultureInfo.CurrentUICulture.DateTimeFormat).ToString("MM/dd/yyyy");
string @DOJ = DateTime.ParseExact(txtDOJ.Text, "dd/MM/yyyy", System.Globalization.CultureInfo.CurrentUICulture.DateTimeFormat).ToString("MM/dd/yyyy");

modify this code to you requirement....
