Question

I have a date that is stored as a string in the format YYYYDDMM. I would like to display that value in a ‘MM/DD/YYYY’ format. I am programming in c#. The current code that I am using is as follows:

txtOC31.Text = dr["OC31"].ToString().Trim();
strOC31date = dr["OC31DATE"].ToString().Trim();
DateTime date31 = DateTime.Parse(strOC31date);
strOC31date = String.Format("{0:MM/dd/yyyy}", date31);

However, I am getting an error because the YYYYMMDD string (strOC31date) is not being recognized as a valid datetime.

Answer 1

DateTime.ParseExact with an example

string res = "20120708";
DateTime d = DateTime.ParseExact(res, "yyyyddMM", CultureInfo.InvariantCulture);
Console.WriteLine(d.ToString("MM/dd/yyyy"));
