var userdateformat = DateTime.ParseExact("20101020", "yyyyMMdd", System.Globalization.CultureInfo.CurrentCulture);
Modify as you want to modify.

IFormatProvider culture = new CultureInfo("en-EN", false); // use your culture info
DateTime dt = DateTime.ParseExact(myDateTimeString, "yyyyMMdd", culture, DateTimeStyles.NoCurrentDateDefault);
yyyyMMdd is input format here.
And then if you wish convert it to string:
String output = String.Format("{0:dd/MM/yyyy}", dt);

Right - except that it probably makes sense either to use `CultureInfo.CurrentCulture` or `CultureInfo.InvariantCulture` dependening on the scenario. – Noldorin Jan 01 '10 at 19:26

I changed user override to false. So it uses default now. But it will not cause any problems here even it overrides. Or am I wrong? – JCasso Jan 01 '10 at 19:32

string strStartDateMain = "20100102";
string strStartDateFinal = new DateTime(Convert.ToInt32strStartDateMain.Substring(0, 4)), Convert.ToInt32(strStartDateMain.Substring(4, 2)), Convert.ToInt32(strStartDateMain.Substring(6))).ToString("dd/MM/yyyy");

I got this answer by doing R&D on that topic. Here If we have a string like "20100102", Than we can get output like "02/01/2010" – Ashish Jan 01 '10 at 19:26

3Indeed, this isn't the right way to do it. This will give somewhat cryptic error messages if the format isn't quite right, or if the string is too short. – Jon Skeet Jan 01 '10 at 19:54

This is only used whene our strStartDateMain will comes in a same range and length. – Ashish Jan 01 '10 at 20:06
