TreeView C＃文件路径

Question

我在查看SelectedTreeView的路径时遇到问题。

private void btn3_Click(object sender, RoutedEventArgs e)
    {
        String TreeViewName = treeView1.SelectedItem.ToString().Replace("Item", String.Empty);
        MessageBox.Show(TreeViewName);
    }

结果是：System.Windows.Controls.TreeView标题： FILENAME s.Count：1

我需要一个文件路径，因为我将TreeView用作文件浏览器，并且，如果我想从treeview中运行文件，它将无法正常工作，因为它会写入结果。

谢谢你的帮助

加：

更改为SelectedValuePath后，文本框为空。 您有其他想法吗？ 解决解决方案后，我需要从TreeView运行文件。 我的代码是

   private void button2_Click(object sender, EventArgs e)
    {
        System.Windows.Forms.FolderBrowserDialog dlg = new System.Windows.Forms.FolderBrowserDialog();

        dlg.Description = "Vyberte složku, kterou přidat";

        if (dlg.ShowDialog() == System.Windows.Forms.DialogResult.OK)
        {
            txtbox1.Text = dlg.SelectedPath;
            ListDirectory(treeView1, dlg.SelectedPath);
        }

    }

     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;

    }

    private void btn3_Click(object sender, RoutedEventArgs e)
    {
        String TreeViewName = treeView1.SelectedValuePath.ToString().Replace("Item", String.Empty);
        txtbox2.Text = TreeViewName;
        System.Diagnostics.Process.Start(TreeViewName);
    }`

对于您的情况，您必须采用TreeViewItem的Header字符串：

private void Button_Click(object sender, RoutedEventArgs e)
{
    TreeViewItem SelectedTreeViewItem = SampleTreeView.SelectedItem as TreeViewItem;
    string FileName = "";

    if (SelectedTreeViewItem != null)
    {
        FileName = SelectedTreeViewItem.Header.ToString(); // Here
    }

    MessageBox.Show(FileName);
}
