Question

我有一个班级“产品”。每个产品都有一个名称。它包含一个“小部件”列表。每个Widget都有一个数字。每个窗口小部件都包含一个窗口小部件列表（可变深度）。最后有一个或多个“套接字”，每个套接字都有一个SocketID和一个Length。换句话说，最后一个Widget不包含另一个Widget而是Sockets。我想要的XML输出看起来像this。

我已经尝试过任何我能想到的技巧来定义我的类序列化产品（ArrayList，List（Widget），XMLInclude等）来实现这个结果 - 没有成功。有没有人遇到过这个问题？

在这里，您可以列出类（对象）的属性及其值。因此，在此步骤之后，您只需将它们保存在您喜欢的格式的简单文本文件中。

Imports System.Reflection

Public Class Form1
    Inherits System.Windows.Forms.Form

#Region " Windows Form Designer generated code "

    Public Sub New()
        MyBase.New()

        'This call is required by the Windows Form Designer.
        InitializeComponent()

        'Add any initialization after the InitializeComponent() call

    End Sub

    'Form overrides dispose to clean up the component list.
    Protected Overloads Overrides Sub Dispose(ByVal disposing As Boolean)
        If disposing Then
            If Not (components Is Nothing) Then
                components.Dispose()
            End If
        End If
        MyBase.Dispose(disposing)
    End Sub

    'Required by the Windows Form Designer
    Private components As System.ComponentModel.IContainer
