推荐答案

事情是这样的：

    public void BindDirectoryToTreeView(string directoryPathToBind)
    {
        TreeNode rootNode = new TreeNode();
        treeView1.Nodes.Add(rootNode);
        RecurseFolders(directoryPathToBind, rootNode);
    }

    public void RecurseFolders(string path, TreeNode node)
    {
        var dir = new DirectoryInfo(path);
        node.Text = dir.Name;

        try
        {
            foreach (var subdir in dir.GetDirectories())
            {
                var childnode = new TreeNode();
                node.Nodes.Add(childnode);

                RecurseFolders(subdir.FullName, childnode);
            }
        }
        catch (UnauthorizedAccessException ex)
        {
            // TODO:  write some handler to log and/or deal with 
            // unauthorized exception cases
        }

        foreach (var fi in dir.GetFiles().OrderBy(c=>c.Name))
        {
            var fileNode = new TreeNode(fi.Name);
            node.Nodes.Add(fileNode);
        }
    }

您会通过调用<$ C $调用代码C> BindDirectoryToTreeView（C：\）; 的实例。请注意，你应该有一个具有此代码的形式命名为TreeView1的TreeView。

You would invoke the code by calling BindDirectoryToTreeView("c:\"); for instance. Note that you should have a treeview named treeView1 on the form that has this code.
