programming level 1... try to write a simple validation function yourself.

Here is the example:

DateTime someDateTime;
var dateTimeString = "99/23/56";

Yes, using the DateTime methods is a good approach. Perhaps using DateTime.TryParseExact might be better if the OP knows the supposed format of the date in advance.

Exactly Bob, Pavel, your method can lead to dates being validated that do not match the intended format.

You need to validate with required culture to make it correct, therefore only 4.
