c# 在树视图后面创建一个 ID

Question

如何在树视图后面添加 ID？代码：string players = "Name:Peter ID:1 Name:karl ID:2 Name:max ID:3 Name:Nils ID:4";var user = players.split().Where(a => a.StartWith("Name:")).ToList();var ID = players.split().Where(a => a.StartWith("ID:")).ToList();for(int i= 0; i<user.Count(); i++) {    var pl = user[i].Substring(user[i].IndexOf(":") + 1);    var plid = ID[i].Substring(ID[i].IndexOf(":") + 1);    treeView1.Nodes.Add(pl);}现在，如果选择用户，我想在文本框中显示 ID编辑：我试过了treeView1.Tag = plid;但这不起作用..

考虑这个模式：

for(int i= 0; i<user.Count(); i++) {

    TreeNode tn = new TreeNode();

    tn.Text = "The name";

    tn.Tag = "The ID";

    treeView1.Nodes.Add(tn);

}
