Title
Body
I have a string in the following format yyyyMMdd and I am trying to get it to look like this: yyyy-MM-dd When I try: string date = "20121004"; Convert.ToDateTime(date).ToString("yyyy-MM-dd"); I get the error: FormatException: String was not recognized as a valid DateTime. Would the following work or would I run into a problem: private string GetValidDate(string date,string format) { DateTime result; if(DateTime.TryParseExact(date, "yyyy-MM-dd", CultureInfo.InvariantCulture, DateTimeStyles.None, out result)) { return date; } else if(DateTime.TryParseExact(date, "yyyyMMdd", CultureInfo.InvariantCulture, DateTimeStyles.None, out result)) { return DateTime.ParseExact(date, "yyyyMMdd", CultureInfo.InvariantCulture).ToString("yyyy-MM-dd"); } else { return "Invalid Date Format"; } }
