如何在C#中创建树视图首选项对话框类型的界面？

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

        // 添加根节点
        TreeNode rootNode = new TreeNode("首选项");
        treeView.Nodes.Add(rootNode);

        // 添加子节点
        TreeNode generalNode = new TreeNode("常规");
        TreeNode appearanceNode = new TreeNode("外观");
        TreeNode advancedNode = new TreeNode("高级");
        rootNode.Nodes.Add(generalNode);
        rootNode.Nodes.Add(appearanceNode);
        rootNode.Nodes.Add(advancedNode);

        // 添加更多子节点
        TreeNode languageNode = new TreeNode("语言");
        TreeNode themeNode = new TreeNode("主题");
        generalNode.Nodes.Add(languageNode);
        appearanceNode.Nodes.Add(themeNode);
    }
}

private void okButton_Click(object sender, EventArgs e)
{
    // 处理确定按钮单击事件
    this.DialogResult = DialogResult.OK;
}

private void cancelButton_Click(object sender, EventArgs e)
{
    // 处理取消按钮单击事件
    this.DialogResult = DialogResult.Cancel;
}

private void preferencesToolStripMenuItem_Click(object sender, EventArgs e)
{
    // 创建并显示首选项对话框
    PreferencesDialog preferencesDialog = new PreferencesDialog();
    if (preferencesDialog.ShowDialog() == DialogResult.OK)
    {
        // 处理确定按钮单击事件
    }
}
