问题描述：

我在 C# Windows 窗体应用程序中有此代码，但我在 WPF 中需要它.你有什么想法?

I have this code in C# Windows Form Application, but I need it in WPF. Do you have any ideas?

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;       
}

感谢您的帮助.

在 WPF 中而不是 Nodes 属性是 Items 属性而不是 TreeNode 你应该使用 TreeViewItem (msdn).

In WPF instead of Nodes property is Items property and instead of TreeNode you should use 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;

    }
