------解决方案--------------------
public Form1()
        {
            InitializeComponent();
            treeView1.HideSelection = true;
        }

TreeNode preNode = null;
        private void treeView1_BeforeSelect(object sender, TreeViewCancelEventArgs e)
        {

            if (preNode != null)
                preNode.ForeColor = Color.Black;
            e.Node.ForeColor = Color.Blue;
            preNode = e.Node;
        }

谢谢以上两位。请注意是webform，不是winform

展开treeview的属性SelectedNodeStyle，找到ForeColor，选择你想要的颜色
