Defining Widening Operator And Narrowing Operator

Question

Here is documentation for Widening and Narrowing Operators.
There is confusion.
Which operator should I create for converting one class to another or one structure to other or structure to class or class to structure.
Any proper example that should explain.
Allow time to reverse.

Answer 1

=
With value types
Module Module1
Sub Main()
Dim x As Short = 1
Dim y As Integer = x
Console.WriteLine(y)
Console.ReadLine()
End Sub
End Module
And with classes
Module Module1
Sub Main()
Dim x As New Dog With {.Head = "Blue"}
Dim y as Mamal = x
Console.WriteLine(y.Head)
Console.ReadLine()
End Sub
End Module
Public Class Mamal
Public Property Head As String
End Class
Public Class Dog
Inherits Mamal
End Class
Success
Cor
Am I using right operator here:
Public Module Main
Sub Main()
Dim Someone As Person = "Someone"
Dim Name As String = Someone
Console.WriteLine(Name)
Console.ReadKey()
End Sub
End Module
Public Class Person
Private _Name As String
Public ReadOnly Property Name As String
Get
Return _Name
End Get
End Property
Public Shared Narrowing Operator CType(Person As Person) As String
Return Person._Name
End Operator
Public Shared Narrowing Operator CType(Person As String) As Person
Return New Person(Person)
End Operator
Sub New(Name As String)
Me._Name = Name
End Sub
End Class
Allow time to reverse.
