文件系统树视图 [英] File System TreeView

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);
    }
}
