在 TreeView C# 中只查找子节点 [英] Find only child nodes in TreeView C#

问题描述

我有以下树

A
+-B
+-C 
| +-D
| +-E
+-F
  +-G
  +-H

我正在寻找B、D、E、G、H.排除有树的节点，只保留它们的子节点.

I am trying to find B, D, E, G, H. Exclude nodes that have tree and just keep their childs.

推荐答案

您可以在 TreeNode 列表中递归收集子项:

You can collect the children recursively in a List of TreeNodes:

 List<TreeNode> children = new List<TreeNode>();

 foreach(TreeNode node in  TV.Nodes) collectChildren(node);

 void collectChildren(TreeNode node)
 {
    if (node.Nodes.Count == 0) children.Add(node) 
    else  foreach(TreeNode n in node.Nodes) collectChildren(n);
 }
