真是大傻B一个啊title竟然出现html标签,该怎么解决

真是大傻B一个啊，title竟然出现html标签
浏览页面的源代码，title里面竟然跑一个<span

HTML code

<head><title><span id="title">恋爱</span></title></head>

HTML code

<asp:Label ID="title" runat="server" Text=""></asp:Label>

C# code

        protected void Page_Load(object sender, EventArgs e)        {            string ST_sql = "select * from ST_news where ST_n_id=" + Request.QueryString["id"] + "";            SqlConnection cn = new SqlConnection(ConfigurationManager.AppSettings["conStr"]); //使用另外一个连接            cn.Open();            SqlCommand cmd = new SqlCommand(ST_sql, cn);            SqlDataReader dr = cmd.ExecuteReader();            //DataList1.DataSource = dr;            //DataList1.DataBind();            //SqlDataReader dr = cmd.ExecuteReader();            if (dr.Read())            {                title.Text = dr["ST_n_title"].ToString();                //content.Text = dr["内容字段名"].ToString();            }        }
