C#之TreeView、TreeNode使用實例代碼

private void treeViewLeft_AfterSelect(object sender, TreeViewEventArgs e)
{
        String strNodeText = e.Node.Text;
        //根據點擊的不同的節點，觸發對應的事件
        switch (strNodeText)
        {
                case "aa":
                this.label1.Text = "fffff";
                break;
                case "bb":
                MDIParent1 md = new MDIParent1();
                md.Show();
                break;
                case "cc":
                break;
        }
}
