Use the following C# 2.0 code to determine whether a string representation of date/time is valid:

string s="04/01/2008"; //string to be converted to date time object.DateTime result;bool success = DateTime.TryParse(s, out result); //try parsing the string to check if 's' contains valid date time.if(success) //returns 'true' if conversion was successful.{  //'result' contains a converted date time object.  ...}

The method for accomplishing the same thing in .NET 1.1 is tedious and less efficient; you need to use a try{}…catch{} block and catch the FormatException.
