            m.ExpInfo = "My Exception Message"
            Throw m
        Catch e As MyException
            Console.WriteLine(e.ExpInfo)
        End Try
    End Sub
End Module

Press any key to continue . . .

Explanation

In the above program, here we created a module Module1. In Module1 we created the class MyException, here we inherit the Exception class and implement a property to set and get the error message.

The Main() is the entry point for the program, here we created the object of MyException class and set the error message, and throw the exception using the Throw keyword. Then the given message will be printed on the console screen.
