Question

我有两个对象：

public class DPMenu
{
    private String menuDescription;
    private List<DPMenuItem> menuItems = new List<DPMenuItem>(4);   // Initialize list with 4 items

    public DPMenu(String menuHeader)
    {
        menuDescription = menuHeader;
    }

    public String Description
    {
        get { return menuDescription; }
        set { menuDescription = value; }
    }

    public List<DPMenuItem> MenuItems
    {
        get { return menuItems; }
    }
}

和

public class DPMenuItem
{
    private String itemDescription;
    private String itemActionLink;

    public String Description
    {
        get { return itemDescription; }
        set { itemDescription = value; }
    }

    public String Link
    {
        get { return itemActionLink; }
        set { itemActionLink = value; }
    }
}

我可以一次创建填充内部列表的对象DPMenu吗？例如

List<DPMenu> mainMenu = new List<DPMenu>();
DPMenu menuHeader;

List<DPMenuItem> menuItems = new List<DPMenuItem>() {
    new DPMenuItem { Description = "A", Link = "A" },
    new DPMenuItem { Description = "B", Link = "B" }
};

menuHeader = new DPMenu("HD").MenuItems.AddRange(menuItems);

但它不起作用...... 谢谢！

为什么不保持简单并只创建另一个重载的构造函数？

public DPMenu(String menuHeader, List<DPMenuItem> itemList)
{
    menuDescription = menuHeader;
    menuItems = itemList;
}

完成后，只需让您的代码执行以下操作即可。不确定你要做什么，但希望这会有所帮助。

  List<DPMenuItem> menuItems = new List<DPMenuItem>() {

                new DPMenuItem { Description = "A", Link = "A" },
                new DPMenuItem { Description = "B", Link = "B" }
  };
  menuHeader = new DPMenu("HD", menuItems);

一次创建内部类中的对象列表
