C# User-Defined ExceptionsC# allows us to create user-defined or custom exception. It is used to make the meaningful exception. To do this, we need to inherit Exception class. C# user-defined exception exampleusing System; public class InvalidAgeException : Exception { public InvalidAgeException(String message) : base(message) { } } public class TestUserDefinedException { static void validate(int age) { if (age < 18) { throw new InvalidAgeException("Sorry, Age must be greater than 18"); } } public static void Main(string[] args) { try { validate(12); } catch (InvalidAgeException e) { Console.WriteLine(e); } Console.WriteLine("Rest of the code"); } } Output: InvalidAgeException: Sorry, Age must be greater than 18 Rest of the code
