Question

我是在树视图中从FTP导入数据。

因为它显示的树视图没有任何名称（节点）..只有结构可见

我的代码是，

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);

当然应该是......

var directoryNode = new TreeNode(p);

..基于您的方法签名？

您的方法中也不存在name和path。

Answer 2

尝试

directoryNode.Text = name;

来自MSDN TreeNode Class

的

文本 - 获取或设置树节点标签中显示的文本。

尝试：

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;
        }

我不确定变量“name”和“path”来自何处？我猜他们等于root和p？我会留给你清理

如何在treeview中解决这个问题？
