C# - Part 45 - Custom Exceptions in C# - Tutorial For Beginners

In C#, custom exceptions allow you to create specific error handling mechanisms for your application's logic. They provide more informative error messages compared to generic exceptions like System.Exception. Here's how to create and use them: Creating Custom Exceptions: Inheritance: Inherit from the System.Exception class. This establishes the class as a type of exception. Naming Convention: By convention, name your custom exception class by ending it with "Exception," for example, InvalidAgeException. Constructors: It's recommended to provide at least three constructors for your custom exception class: A parameterless constructor for scenarios without a specific message. A constructor that takes a message string for providing more context about the error. A constructor that takes a message string and an inner exception. This allows you to chain exceptions, which can be useful for debugging purposes. Complete list of C# exceptions : https://mikevallotton.wordpress.com/2009/07/08/net-exceptions-all-of-them/
