如何在Treeview中解决此问题？

Question

i am import data from FTP in treeview.

in that its displaying treeview without any name(node)..only structure is visible

my code is,

treeView1.Nodes.Clear();
            treeView1.Nodes.Add(CreateDirectoryNode(root, "root"));



private TreeNode CreateDirectoryNode(string root, string p)
        {
            var directoryNode = new TreeNode(name);
            var directoryListing = GetDirectoryListing(path);

            var directories = directoryListing.Where(d => d.IsDirectory);
            var files = directoryListing.Where(d => !d.IsDirectory);

            foreach (var dir in directories)
            {
                directoryNode.Nodes.Add(CreateDirectoryNode(dir.FullPath, dir.Name));
            }
            foreach (var file in files)
            {
                directoryNode.Nodes.Add(new TreeNode(file.Name));
            }
            return directoryNode;
        }

Answer 1

var directoryNode = new TreeNode(name);

Surely this should be...

var directoryNode = new TreeNode(p);

..based on your method signature?

Also name and path don't exist within your method.

Answer 2

Try

directoryNode.Text = name;

from the MSDN TreeNode Class

Text - Gets or sets the text displayed in the label of the tree node.

try:

private TreeNode CreateDirectoryNode(string root, string p)
        {
            var directoryNode = new TreeNode(name);
            directoryNode.Text = name;
            var directoryListing = GetDirectoryListing(path);

            var directories = directoryListing.Where(d => d.IsDirectory);
            var files = directoryListing.Where(d => !d.IsDirectory);

            foreach (var dir in directories)
            {
                directoryNode.Nodes.Add(CreateDirectoryNode(dir.FullPath, dir.Name));
            }
            foreach (var file in files)
            {
                TreeNode tn = new TreeNode(file.Name);
                tn.Text = file.Name
                directoryNode.Nodes.Add(new TreeNode(tn));
            }
            return directoryNode;
        }

I am unsure where the variables "name" and "path" are coming from? I guess they equate to root and p? I will leave that for you to clear up
