包含列表的VB.NET Serealize結構

Question

我正在尋找一種方法來序列化包含不同類型的對象，如字符串，整數和集合的結構。

我有這樣的數據結構：

Dim database as New mainStruct 

<Serializable()> Structure mainStruct 
    Public name As String 
    Public address As String 
    Public Shared bookings As IList(Of booking) = New List(Of booking) 
End Structure 

<Serializable()> Structure booking 
    Public id As Integer 
    Public category As String 
    Public description As String 
End Structure 

運行串行：

Dim fs As FileStream = New FileStream("x.bin", FileMode.OpenOrCreate) 
    Dim serial As New XmlSerializer(GetType(mainStruct)) 
    serial.Serialize(fs, database) 
    fs.Close() 

輸出只包含所有非集合變量，如：

<?xml version="1.0"?> 
    <mainStruct xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"> 
    <name>foo</name> 
    <address>bar</address> 
</mainStruct> 

我怎麼能序列化預訂集合，而不使用GetType（List（Of booking））創建單獨的文件？

謝謝！

共享成員不是串行化，因爲序列是所有有關保存類/結構實例，和共享成員不是一個實例的一部分。

實例屬性添加到您的結構，你應該是好去：

Public Property bookingList As IList(Of booking) 
    Get 
     Return mainStruct.bookings 
    End Get 
    Set(value As IList(Of booking) 
     mainStruct.bookings = value 
    End Set 
End Property 

如果你想被稱爲標籤<bookings>你可以申請一個XmlArray attribute的財產：

<XmlArray("bookings")> _ 
Public Property bookingList As IList(Of booking) 
    ...same code as above... 
End Property
