文件系统的TreeView [英] File System TreeView

问题描述

林与文件系统的工作，我有一个List＆LT;>具有作为一个属性的文件路径文件的对象。基本上我需要.NET创建一个TreeView，但即时通讯奋力想到去这样做，因为我需要从列表中创建一个树形结构的最佳方式，如：

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...

该列表不是在所有结构化的，我不能让当前的对象结构的任何变化。

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

我工作在C＃。

非常感谢所有谁贡献

推荐答案

如果您想与琴弦坚持这样的事情会工作...

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);
    }
}
