Try casting it to a DateTime inside of a try...catch? Use RegEx?

DateTime.TryParse() and such.

Thank you guys. I used DateTime.TryParse().

Also, another question: How to quickly convert a collection into an array?

Thanks again.

It depends on the collection. ArrayList and List<T> have a parameterless
ToArray method, which creates an array containing elements from the
collection. In addition, ICollection and ICollection<T> exposes a CopyTo
method, which can be used in the following manner:

Widget[] arr = new Widget[coll.Count];
coll.CopyTo(arr, 0);
