C＃WPF中的TreeView目录

我在C＃Windows窗体应用程序中有这个代码，但我需要它在WPF中。 你有什么想法？

private void button1_Click(object sender, EventArgs e) { ListDirectory(treeView1, "C:\\Users\\Patrik\\Pictures"); } 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; } 

感谢帮助。

在WPF而不是Nodes属性中是Items属性，而不是TreeNode您应该使用TreeViewItem （ msdn ）。

  private void ListDirectory(TreeView treeView, string path) { treeView.Items.Clear(); var rootDirectoryInfo = new DirectoryInfo(path); treeView.Items.Add(CreateDirectoryNode(rootDirectoryInfo)); } private static TreeViewItem CreateDirectoryNode(DirectoryInfo directoryInfo) { var directoryNode = new TreeViewItem { Header = directoryInfo.Name }; foreach (var directory in directoryInfo.GetDirectories()) directoryNode.Items.Add(CreateDirectoryNode(directory)); foreach (var file in directoryInfo.GetFiles()) directoryNode.Items.Add(new TreeViewItem { Header = file.Name }); return directoryNode; }
