C# 遍历TreeView所有节点

 

public void PrintTreeViewNode(TreeNodeCollection node)
        {
            foreach (TreeNode n in node)
            {
                Response.Write(n.Text+",");
                PrintTreeViewNode(n.ChildNodes);
            }
        }


调用  PrintTreeViewNode(TreeView1.Nodes);
