C# User-Defined Exceptions

C# 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 example

 using 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
