推荐答案

你的问题不是很清楚。

如果你想在树视图中显示文件夹结构，请浏览

C＃文件浏览器 [ ^ ]

增强的BrowseForFolder样式TreeView [ ^ ]。



这里 [ ^ ]是一个更简单的示例，可以帮助您入门。

Your question is not very clear.
If you are looking to display folder structures in a treeview, go through
C# File Browser[^]
Enhanced BrowseForFolder styled TreeView[^].

Here[^] is a simpler example that can help you get started.

private void ListDirectory(TreeView treeView, string path)
        {
            treeView.Nodes.Clear();
            var rootDirectoryInfo = new DirectoryInfo(path);
            treeView.Nodes.Add(CreateDirectoryNode(rootDirectoryInfo));
        }

        private static TreeNode CreateDirectoryNode(DirectoryInfo directoryInfo)
        {
            var directoryNode = new TreeNode(directoryInfo.Name);
            foreach (var directory in directoryInfo.GetDirectories())
                directoryNode.Nodes.Add(CreateDirectoryNode(directory));
            foreach (var file in directoryInfo.GetFiles())
                directoryNode.Nodes.Add(new TreeNode(file.Name));
            return directoryNode;
        }

        private void button1_Click(object sender, EventArgs e)
        {
            foreach (var obj in opt.checkedListBox1.CheckedItems)
            {
                ListDirectory(treeView1, "E:\\mails\\" + obj);
               
                treeView1.ExpandAll();
            }

        }

我已经实现了以上所述，但无法循环查看所有已检查的文件夹..请指导我哪里出错???

I hav achieved the above as follows but am unable to loop for all the checked folders.. please guide me where am going wrong???

你可以点击树节点上的函数，一旦节点事件火灾，您可以检查新路径并生成新的子节点，我已经完成并且它工作了



如果你想我可以与你分享< br $>


谢谢，

Hi,

You can call function on click on tree node, once the node event fire, you can check for the new path and generate the new sub node, I have done and it worked

if you want I can share the same with you

Thanks,
