用什么集合来存储树结构? [英] What collection to store a tree structure?

问题描述

我想在集合中存储组织结构图.我认为树数据结构最适合我的需求，因为我需要向一个节点添加多个节点.

I want to store an organisation chart in a collection. I think a tree data structure will be best suited to my needs, as I need to add multiple nodes to one node.

LinkedList 仅提供将一个节点添加到另一个节点的功能，如果我理解正确的话.

LinkedList only provides adding one node to another node, if I understand it correctly.

我看过 C5 treeset 集合，但它似乎没有 Add() 方法可以将 2 个以上的节点添加到一个节点.

I have looked at C5 treeset collection, but it doesn't seem to have Add() method to add more than 2 nodes to one node.

我还查看了 Windows 窗体库中的 Treeview 类，但我不想将 Windows 窗体 dll 添加到我的项目中，因为我正在构建一个服务层应用.(或者还好吗?)

I have also looked at Treeview class from Windows Forms library, but I do not want to add Windows forms dll to my project, since I am building a service layer application. (or is it fine?)

我不想写自己的树集合类，如果第三方已经提供了一个?

I do not want to write my own tree collection class, if there is already one provided by 3rd party?

有什么建议吗?

谢谢

推荐答案

这样的事情可以作为一个起点.通过使用泛型，这个人可以拥有一棵任何东西的树

Something like this can be a starting point. By using generics this one can hold a tree of anything

class TreeNode<T>
{
    List<TreeNode<T>> Children = new List<TreeNode<T>>();

    T Item {get;set;}

    public TreeNode (T item)
    {
        Item = item;
    }

    public TreeNode<T> AddChild(T item)
    {
        TreeNode<T> nodeItem = new TreeNode<T>(item);
        Children.Add(nodeItem);
        return nodeItem;
    }
}

一个包含字符串树的样本

A sample which holds a tree of strings

string root = "root";
TreeNode<string> myTreeRoot = new TreeNode<string>(root);
var first = myTreeRoot.AddChild("first child");
var second = myTreeRoot.AddChild("second child");
var grandChild = first.AddChild("first child's child");
