我有一个类“产品”。每个产品都有一个名称。它由“小部件”列表组成。每个小部件都有一个编号。每个 Widget 又包含一个 Widget 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 和一个长度。换句话说，最后一个 Widget 不是由另一个 Widget 组成，而是由 Sockets 组成。我想要的 XML 输出看起来像这样。

我已经尝试了我能想到的任何技巧来定义我的类 Product 以进行序列化（ArrayList、List(of Widget)、XMLInclude 等以实现该结果 - 没有成功。以前有人遇到过这个问题吗？

在这里，您可以列出类（对象）的属性及其值。因此，在这一步之后，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
