DateTime.TryParse all possible type of dates

Iwant to check if date is in correct type. there is many possibilities of correct dates like 02.08.2010, 2.8.2010, 02.8.2010 02.08, 02.August,...
i can test each on with code like this
if (DateTime.TryParse(DateTime.ParseExact(date, "dd.M.", new CultureInfo("sl-SI")).ToString(), out dt))
but then i can have 40 if statements. Is it possible to check all dates with one if statement or one loop? {
