我正在使用 XML 反序列化来处理来自我正在调用的 api 的 XML 响应。我要返回的属性之一需要根据类中的另一个属性进行更改。一个例子：

<XmlRoot("Foot")> _
Public Class Foo
    Private m_bar1 As String
    Private m_bar2 As String
    Private m_rawbar2 As String

    <XmlAttribute("Bar1")> _
    Public Property Bar1() As String
        Get
            return m_bar1
        End Get
        Set(value As String)
            m_bar1 = value
        End Set
    End Property

    <XmlAttribute("Bar2")> _
    Public Property RawBar2() As String
        Get
            return m_rawbar2
        End Get
        Set(value As String)
            m_rawbar2= value

            'This won't (always) work because the order in which the 
            'properties are deserialized is unknown
            'm_bar2 = m_bar1 & m_rawbar2 
        End Set
    End Property

    <XmlIgnore()> _
    Public ReadOnly Property Bar2() As String
        Get
            return m_bar2
        End Get
    End Property
End Class

在我的情况下， bar1 将是一个 url，而 bar2 将是同一域上的相对路径。我唯一可以设置 m_bar2 的时间是当每个属性都被反序列化时，因为顺序是未知的。最好的方法是什么？
