A question

I got a string value that actually get from directoryInfo. What i wanted to accomplish is to convert the string value to a date value for making comparison.

The folder name is sample like this C:\FOLD\20111120 and properly another folder path is like this C:\FOLD\20111021

20111120 is actually a date format. I am trying to convert it into date format to made some comparison decide to deleting the whole directory or not.

I think i shall paste my code here

DirectoryInfo dir = new DirectoryInfo(_FolderPath);  foreach (DirectoryInfo f in dir.GetDirectories()) {      String folderName = f.ToString();      DateTime ConDt = Convert.ToDateTime(folderName);      Console.WriteLine(ConDt);      Console.WriteLine(ConDt.GetType());    //Console.WriteLine(folderName.GetType());    //Console.WriteLine(f.GetType()); } 

I tried with Convert.toDatetime() and i get error that unable to made the converstion.How can i do so with this?

You should have to use DateTime.TryParseExact.

var newDate = DateTime.ParseExact("20111120",                                    "yyyyMMdd",                                     CultureInfo.InvariantCulture); 

OR

string str = "20111021"; string[] format = {"yyyyMMdd"}; DateTime date;  if (DateTime.TryParseExact(str,                             format,                             System.Globalization.CultureInfo.InvariantCulture,                            System.Globalization.DateTimeStyles.None,                             out date)) {      //valid }
