But I don''t know how to do this.I found that there was no "click" event about treenodes...

推荐答案

不，Click事件是TreeView的一部分.
得到事件，确定它是哪个节点，然后离开...

No, the Click event is part of the TreeView.
You get the event, decide which node it is and off you go...

您可以尝试订阅 NodeMouseClick 的 AfterSelect 事件:

You can try subscribing to AfterSelect of NodeMouseClick events:

// Handle the After_Select event.
    private void TreeView1_AfterSelect(System.Object sender,
        System.Windows.Forms.TreeViewEventArgs e)
    {
        // Vary the response depending on which TreeViewAction
        // triggered the event.
        switch((e.Action))
        {
            case TreeViewAction.ByKeyboard:
                MessageBox.Show("You like the keyboard!");
                break;
            case TreeViewAction.ByMouse:
                MessageBox.Show("You like the mouse!");
                break;
        }
    }

或

or

void treeView1_NodeMouseClick(object sender,
    TreeNodeMouseClickEventArgs e)
{
    textBox1.Text = e.Node.Text;
}

格里夫！谢谢您的回答，我想我必须了解有关树视图控件的更多信息……非常感谢！我会试着像你说的那样！
