导读：Namespace mySpace Public Class MyClass1 Private Property _myID As String Private Property _myName As String Private Property Y As Integer Public Property X As Integer Public Property myID As String Get Return _myID End Get Set(value As Stri

Namespace mySpace
Public Class MyClass1

Private Property _myID As String
Private Property _myName As String
Private Property Y As Integer
Public Property X As Integer

Public Property myID As String
Get
Return _myID
End Get
Set(value As String)
_myID = value
End Set
End Property
Public Property myName As String
Get
Return _myName
End Get
Set(value As String)
_myName = value
End Set

End Property

Public Property mX As Interger
Get
X
End Get
Set(value As Inter)
X=2*Y
End Set

End Property

End Class
End Namespace

注释：这里定义为属性的意义

1 通过私有属性来访问公有属性，达到安全控制的目的

2 通过私有属性来访问公有属性，还可以在赋值的时候，做一些限制或者特殊的处理，计算。达到对私有属性更高一层的控制。某一个属性的值改变了，自动触发另外一个属性的值。不用在外部通过事件的代码来实现。
