How to write User Defined exceptions in C#?

Question

hi can any one tell me how to write user defined exceptions in C#?As we have in Java can we write in C#?

Answer 1

You want to inherit from System.Exception and preferrably provide (at minimum) the same public constructors and pass the parameters on to the base constructors. Add the relevant properties and/or methods you deem appropriate for your particular need.

public class MyException : System.Exception
{
     public MyException() : base() { }
     public MyException(string message) : base(message) { }
     public MyException(string message, Exception innerException) : base(message, innerException) { }
}
