从概念上讲,似乎派生类应该能够使用读写属性覆盖readonly属性.为什么这不可能？
Public Class Base
Protected _name As String
Public Overridable ReadOnly Property Name() As String
Get
return _name
End Get
End Property
End Class
Public Class Derived
Inherits Base
Public Overrides Property Name() As String
Get
Return MyBase.Name
End Get
Set(ByVal value As String)
_name = value
End Set
End Property
End Class
