Convert A String Into Date?

Oct 14, 2011

I am trying to convert a string into Date (to put it later into INSERT command). My problem is that the string I am reading is always different (there is no rule what format it is going to be - as this is user-dependent).I found such piece of code on the stackoverflow:

DateTime myDate =
DateTime.ParseExact("2009-05-08 14:40:52,531",
"yyyy-MM-dd HH:mm:ss,fff",
System.Globalization.CultureInfo.InvariantCulture)

but in my case it will not work as I don't know what kind of format I am going to import.Is there any universal import function which checks all known formats? If now how should I write it?

I have a string that holds a value in the format of ddMMyyhhmmss.

Example 240512024707

I need to be able to convert this date to a real .NET Date object.

I am currently using CDate but it seems CDate does not recognize the format, is there any way of specifying the string format to CDate ???

row.Item("NoteDate") = CDate(n.noteText.Substring(0, 12).ToString).ToString("dd/MM/yyyy hh:mm:ss")
