我有一个使用递归从 XML 生成控件的过程。系统很复杂。我已经尽可能小了。最后一个插件是可见的，其余的不可见。我怀疑GenerateControls()是坏了。为什么不显示所有插件？

形式：

public partial class PdLoadingForm : Form
{        
    public PdLoadingForm()
    {
        InitializeComponent();

        PhysDocDocument document = MockDocument();//Generate some mock data
        GenerateControls(document.Nodes);//Generate controls using recursion.
    }

    private PhysDocDocument MockDocument()
    {
        PhysDocDocument document = new PhysDocDocument();
        PhysDocNode outerNode = new PhysDocNode();
        outerNode.Display = "outer Node";

        //Generate 3 plugins.  Each plugin generates a textbox.  I only see 1 Textbox.
        //I expect to see 3 textboxes.
        for(int i = 0; i < 3; i++)
        {
            PhysDocNode innerNode = new PhysDocNode() { Display = "test" + i };

            PhysDocNode innerNodeContent = new PhysDocNode() { Display = "IO" };
            innerNodeContent.Plugins.Add(new Plugin());

            innerNode.Nodes.Add(innerNodeContent);
            outerNode.Nodes.Add(innerNode);
        }

        document.Nodes.Add(outerNode);

        return document;

    }

    private void GenerateControls(List<PhysDocNode> children, CustomControl parent = null)
    {
        foreach (PhysDocNode node in children)
        {
            CustomControl parentControl = new CustomControl(node);                

            if (node.Nodes != null && node.Nodes.Count > 0)
                GenerateControls(children: node.Nodes, parent: parentControl);

            foreach (Plugin plugin in node.Plugins)
            {  
                Control childControl = plugin.CreateUIControl();//Ask the plugin for a control
                AddControl(childControl: childControl, parent: parentControl);
            }

            AddControl(childControl: parentControl, parent: parent);
        }
    }

    private void AddControl(Control childControl, Control parent)
    {
        childControl.Dock = DockStyle.Top;

        if(parent == null)//add to form
            Controls.Add(childControl);
        else//add to parent
            parent.Controls.Add(childControl);
    }
}

插入：

public class Plugin
{
    [XmlAttribute]
    public string type { get; set; }

    public Control CreateUIControl()
    {
        TextBox testBox = new TextBox();
        testBox.Text = "plugin";

        return testBox;
    }
}

自定义控件：

public class CustomControl: UserControl
{    
    public CustomControl(PhysDocNode nodeInfo)
    {
        InitializeComponent();
        Label label = new Label();
        label.Text = "Rtb..." + nodeInfo.Display;
        label.Dock = DockStyle.Top;
        contentPanel.Controls.Add(label);//just drop a panel on the user control in design view
    }

查看文档，似乎Dock 属性管理标签相对于其父级的定位。

例如，您可以尝试通过将其Top 属性的值设置为控件列表中其索引的倍数来指定标签位置。
