            </td>
        </tr>
    </table>
    </form>
</body>
</html>

这是服务器端代码:

Here is server side code:

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.UI;
using System.Web.UI.WebControls;
public partial class ZTest2 : System.Web.UI.Page
{
    protected void Page_Load(object sender, EventArgs e)
    {
    }
    protected void btnGetTime_Click(object sender, EventArgs e)
    {
        txtServerTime.Text = DateTime.Now.ToString("dd-MMM-yy hh:mm:ss");
    }
}
