推荐答案

使用其Parent属性从选定节点移动到其父节点，并相应地修改路径结构.您可以使用递归，但是您不需要它，因此最好使用循环，直到父级为null.

Move from a selected node to its parent using its Parent property and modify the path structure accordingly. You can use recursion but you don''t need it, so better use a cycle until the parent is null.

您可以将XML文件位置存储在节点的Tag属性中

You can store the XML file location in the Tag attributes of the node

private void tvFileMaps_MouseClick(object sender, MouseEventArgs e)
{
    TreeNode tn = SelectedTree.GetNodeAt(e.Location.X, e.Location.Y);
    string XMLLocation = tn.Tag != null ? tn.Tag.ToString() : string.Empty;
}

在TreeView中添加TreeNode时，请添加Tag 属性以及XML文件的位置.

At the time of adding the TreeNode in the treeView add the Tag property with the location of the XML file.
