以递归方式将子节点添加到树中

问题描述

嗨peeps ..


我使用来自IE COntrols的TreeView控件创建一个目录

结构，并尝试递归执行。


代码有效，但我的问题是如何让子目录显示为树中的叶子而不是新的分支？

？


这里是代码..


private void RecurseTree（DirectoryInfo theDir，int nLevel）

{

TreeNode libraryNode = null;

DirectoryInfo [] subFolders = theDir.GetDirectories（）;


//填充树

for（int i = 0; i< subFolders.Length; i ++）

{

libraryNode = new TreeNode（）;

libraryNode.Text = subFolders [i] .Name;

treeDocuments.Nodes.Add（libraryNode）;

libraryNode = null;

RecurseTree（subFolders [i]，nLevel + 1）;

}

}


任何帮助表示赞赏！

在树中出现

Hi peeps..

Im using the TreeView control from IE COntrols to create a directory
structure, and trying to do it recursively.

The code works, but my question is simply how can I make the subdirs appear
as leaves in the Tree, rather than as new branches?

Here''s the code..

private void RecurseTree(DirectoryInfo theDir, int nLevel)
{
TreeNode libraryNode = null;
DirectoryInfo[] subFolders = theDir.GetDirectories();

// populate the tree
for (int i=0; i < subFolders.Length; i++)
{
libraryNode = new TreeNode();
libraryNode.Text = subFolders[i].Name;
treeDocuments.Nodes.Add(libraryNode);
libraryNode = null;
RecurseTree(subFolders[i], nLevel+1);
}
}

Any help appreciated!

Cheers
Dan
