即重新present树对象 [英] Objects that represent trees

问题描述

有没有在C＃中的任何对象（或.NET）的重新presents二叉树（或好奇）和正叉树？

Are there any objects in C# (or in .net) that represents a binary tree (or for curiosity) and n-ary tree?

我说的不是presentation树形控件，但作为模型对象。

I am not talking about presentation tree controls, but as model objects.

如果不是，请问有什么好的外部实现？

If not, are there any good external implementations?

推荐答案

在 NGenerics 项目是数据结构和算法的真棒集合包括二叉树。

The NGenerics project is a awesome collection of data structures and algorithms including a Binary Tree.

public class BinaryTree<T> : IVisitableCollection<T>, ITree<T>
{
  // Methods
  public void Add(BinaryTree<T> subtree);
  public virtual void breadthFirstTraversal(IVisitor<T> visitor);
  public virtual void 
         DepthFirstTraversal(OrderedVisitor<T> orderedVisitor);
  public BinaryTree<T> GetChild(int index);
  public bool Remove(BinaryTree<T> child);
  public virtual void RemoveLeft();
  public virtual void RemoveRight();

  // ...

  // Properties
  public virtual T Data { get; set; }
  public int Degree { get; }
  public virtual int Height { get; }
  public virtual bool IsLeafNode { get; }
  public BinaryTree<T> this[int i] { get; }
  public virtual BinaryTree<T> Left { get; set; }
  public virtual BinaryTree<T> Right { get; set; }

  // ...
}
