xml 中的重复元素，其中 vb class 在导出为序列化到 xml 时有一个属性的列表

Question

我有一个 class 定义如下：

Public Class details
    Public Property description As String
    Public Property rooms As New List(Of rooms)
End Class

Public Class rooms
    Public Property room_name As String
    Public Property room_description As String
End Class

它的房子详细信息，每间房子有多个房间。

我编码如下：

Dim clsPDts As New details
clsPDts.description = "test property name"
Dim tmpRoom As New rooms
tmpRoom.room_name = "BEDROOM ONE"
tmpRoom.room_description = "Fitted wardrobes with mirror sliding doors"
clsPDts.details.rooms.Add(tmpRoom)

然后输出如下：

Dim objStreamWriter As New StreamWriter("D:\Product.xml")
Dim x As New XmlSerializer(clsPDts.GetType)
x.Serialize(objStreamWriter, clsPDts)
objStreamWriter.Close()

XML 文件应该如下所示，因为它必须是这样的格式：

<details>
    <description>A Two Bedroomed Second Floor Apartment Situated Within this Seafront Development.</description>
    <rooms>
      <room_name>COMMUNAL HALLWAY</room_name>
      <room_description>Communal entrance door with entry phone system.</room_description>
    </rooms>
    <rooms>
      <room_name>ENTRANCE HALL</room_name>
      <room_description>Personal entrance door. Built-in airing cupboard, storage heater.</room_description>
    </rooms>
    <rooms>
      <room_name>BEDROOM ONE</room_name>
      <room_description>Fitted wardrobes with mirror fronted sliding doors</room_description>
    </rooms>
</details>

但它目前如下所示，其他多个房间周围有额外的房间元素：

<details>
  <description>A Two Bedroomed Second Floor Apartment Situated Within this Seafront Development.</description>
  <rooms>
    <rooms>
      <room_name>COMMUNAL HALLWAY</room_name>
      <room_description>Communal entrance door with entry phone system.</room_description>
    </rooms>
    <rooms>
      <room_name>ENTRANCE HALL</room_name>
      <room_description>Personal entrance door. Built-in airing cupboard, storage heater.</room_description>
    </rooms>
    <rooms>
      <room_name>BEDROOM ONE</room_name>
      <room_description>Fitted wardrobes with mirror fronted sliding doors</room_description>
    </rooms>
  </rooms>
</details>

我不确定如何去掉多余的外部元素？

Answer 1

您需要像下面的代码一样将标签指定为 XmlElement

Imports System.Xml
Imports System.Xml.Serialization
Module Module1

    Sub Main()

    End Sub

End Module

<XmlRoot("details")>
Public Class details
    <XmlElement("description")>
    Public Property description As String
    <XmlElement("rooms")>
    Public Property rooms As New List(Of rooms)
End Class

<XmlRoot("rooms")>
Public Class rooms
    <XmlElement("room_name")>
    Public Property room_name As String
    <XmlElement("room_decription")>
    Public Property room_description As String
End Class
