我想在 VB.NET 中创建一个层次结构,如下所示
<Parent>
<Child1><Child1 />
<Child2>
<Subchild1 />
<Subchild2 />
<Child2 />
</Parent>
我为
parent
创建了实体类和集合类, child1
, child2
, subchild1
和 subchild2
.我需要将父集合类实例传递给 XML 序列化器类以生成上面给出的分层节点结构。我不知道该怎么做。请给我一个 sample 。实体:
Public class Parent
Public property FirstName as string
Public property LastName as string
End Class
Public Class Child1
Public property Color as string
End class
Public Class Child2
Public property Color as string
End class
Public Class SubChild1
Public property FirstName as string
End Class
Public Class SubChild2
Public property FirstName as string
End Class
Collection Class:
Public class ParentS
Public Function Add(objrow as Parent, byref skey as object) as Parent
我是否需要将子类作为属性添加到父类?如何做到这一点并创建上面给出的结构。请帮忙。谢谢。
最佳答案
你可以这样:
Public Class Node
Public Property FirstName As String
Public Property LastName As String
Private _childNodes As New List(Of Node)
Public Property ChildNodes As List(Of Node)
Get
Return _childNodes
End Get
Set
_childNodes = value
End
End Property
End Class
用法 Dim parent As New Node
parent.FirstName = "John"
parent.LastName = "Doe"
Dim child_1 As New Node()
child_1.FirstName = "Jane"
child_1.LastName = "Doe"
parent.ChildNodes.Add(child_1)
更新Public Class Employee
Public Property FirstName As String
Public Property LastName As String
End Class
Public Class Department
Private _employees As New List(Of Employee)
Private _subDepartments As New List(Of Department)
Public Property SubDepartments As List(Of Department)
Get
Return _subDepartments
End Get
Set
_subDepartments = value
End
End Property
Public Property Employees As List(Of Employee)
Get
Return _employees
End Get
Set
_employees = value
End
End Property
End Class
用法 Dim dept As New Department
dept.Name = "Accounting"
Dim subDept1 As New Department()
subDept1.Name = "Audit"
dept.SubDepartments.Add(subDept1)
Dim employee1 As New Employee()
employee1.FirstName = "John"
employee1.LastName = "Doe"
dept.Employees.Add(employee1)
希望有帮助!这可以进一步重构,但这应该有效。
