how to convert date from yyyyMMdd format to mm-dd-yyyy fomrat

I have a string which contains date in yyyyMMdd format. I want to convert that date into system date format using ConvertTo.DateTime() method or any other simple method.

string value = "19851231";  //yyyyMMdd

DateTime dateTime = 1985/12/31;

string time = "19851231";
DateTime theTime= DateTime.ParseExact(time,
                                        "yyyyMMdd",
                                        CultureInfo.InvariantCulture,
                                        DateTimeStyles.None);

have at look at the static methods DateTime.Parse() and DateTime.TryParse(). They will allow you to pass in your date string and a format string, and get a DateTime object in return.
