How do I convert date in integer format to DateTime without using DateTime?

I have tried:

Regex regex = new Regex(@"^(0[1-9]|1[012])(0[0-9]|1[0-9]|2[0-9]|3[01])(1[789]|[2-9][0-9])\d\d+$");
if (regex.IsMatch(txt_fromdate.Text) == true)
            {
                DateTime dt = DateTime.ParseExact(txt_fromdate.Text, "MMddyyyy", null);
            }

Hey Prithivi989, i think we can't get the exact date.

Case 1: If the number is 12122012 means we can find out the date (12th December 2012).

Case 2: If the number is 122012 means we can find out the date (2nd January 2012).

Case 3: If the number is 1232012 means we can find out the date (3rd December 2012).

Case 4: But the problem is if the number is 1122012 means then can't say the exact date (2nd November 2012 or 12th January 2012).
