使用文件系统目录结构填充TreeView

使用文件系统目录结构填充TreeView

选项1：递归方法：

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;}

选项＃2：非递归方法：

private static void ListDirectory(TreeView treeView, string path){    treeView.Nodes.Clear();    var stack = new Stack<TreeNode>();    var rootDirectory = new DirectoryInfo(path);    var node = new TreeNode(rootDirectory.Name) { Tag = rootDirectory };    stack.Push(node);    while (stack.Count > 0)    {        var currentNode = stack.Pop();        var directoryInfo = (DirectoryInfo)currentNode.Tag;        foreach (var directory in directoryInfo.GetDirectories())        { var childDirectoryNode = new TreeNode(directory.Name) { Tag = directory }; currentNode.Nodes.Add(childDirectoryNode); stack.Push(childDirectoryNode);        }        foreach (var file in directoryInfo.GetFiles()) currentNode.Nodes.Add(new TreeNode(file.Name));    }    treeView.Nodes.Add(node);}
