文件系统树视图

本文介绍了文件系统树视图的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！ 问题描述

我正在使用文件系统，并且我有一个以文件路径作为属性的文件对象的 List.基本上我需要在 .NET 中创建一个树视图，但我正在努力想出最好的方法来做到这一点，因为我需要从如下列表中创建一个树结构:

Im working with file systems and I have a List<> of file objects that have the file path as a property. Basically I need to create a treeview in .NET but im struggling to think of the best way to go about doing this as I need to create a tree structure from a list like:

C:/WINDOWS/Temp/ErrorLog.txt C:/Program Files/FileZilla/GPL.html C:/Documents and Settings/Administrator/ntuser.dat.LOG

等等....

该列表根本没有结构化，我无法对当前对象结构进行任何更改.

The list is not structured at all and I cant make any changes to the current object structure.

我正在使用 C#.

推荐答案

如果你想坚持使用字符串，这样的事情会奏效...

If you wanted to stick with the strings something like this would work...

TreeNode root = new TreeNode(); TreeNode node = root; treeView1.Nodes.Add(root); foreach (string filePath in myList) // myList is your list of paths { node = root; foreach (string pathBits in filePath.Split('/')) { node = AddNode(node, pathBits); } } private TreeNode AddNode(TreeNode node, string key) { if (node.Nodes.ContainsKey(key)) { return node.Nodes[key]; } else { return node.Nodes.Add(key, key); } }
