Determine Whether a String Representation of Date/Time is Valid

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.
