        </asp:Repeater>
        <asp:Button ID="Button1" runat="server" Text="退出登录" />
    </form>
</body>

C#后台

 protected void Page_Load(object sender, EventArgs e)
    {
        Button1.Click += Button1_Click;
        List<Model> list = null;
        if (Request.Cookies["User"] == null)
        {
            Response.Redirect("Default.aspx");//如果Cookie为空（未保存登录状态）自动跳回登录界面
        }
        else
        {
            Label1.Text = Request.Cookies["User"].Value + "欢迎回来！";
        }
        list = new Operation().SelectUtb();
        Repeater1.DataSource = list;//指向要绑定的数据
        Repeater1.DataBind();//绑定数据
        if (Session["Detele"] != null)//点击删除根据页面传回的值确定删除是否成功
        {
            if (Convert.ToBoolean(Session["Detele"]))
            {
                Response.Write("<script>alert('删除成功！');</script>");
                Session["Detele"] = null;
            }
            else
            {
                Response.Write("<script>alert('删除失败！');</script>");
                Session["Detele"] = null;
            }
        }
        if (Session["Update"] != null)//点击修改根据页面传回的值确定是否成功
        {
            if (Convert.ToBoolean(Session["Update"]))
            {

                Session["Update"] = null;
            }

                Session["Update"] = null;
            }
        }
    }

    void Button1_Click(object sender, EventArgs e)
    {
        Response.Cookies["User"].Expires = DateTime.Now.AddDays(-1);//点击退出将Cookie的过期时间变为前一天使得保存的登录状态失效
        Response.Write("<script>window.location.href=window.location.href</script>");//刷新本页面，由于Cookie没有值将会自动跳回登录界面
    }

4.删除界面：

html部分没有东西

C#后台

protected void Page_Load(object sender, EventArgs e)
    {
        Session["Detele"] = new Operation().delete(Request["User"]);//根据点击是传过来的用户编号进行删除操作并返回一个Session确定是否成功。
        Response.Write("<script>window.open('Default3.aspx','_parent');</script>");//在本页面返回登录界面
    }

5.修改界面：
