推荐答案

ajax计时器控件与您所需的完全相同

代码

ajax timer control do the exactly same as you required

Code

<asp:scriptmanager id="ScriptManager1" runat="server" xmlns:asp="#unknown" />
        <asp:timer runat="server" id="UpdateTimer" interval="5000" ontick="UpdateTimer_Tick" xmlns:asp="#unknown" />
        <asp:updatepanel runat="server" id="TimedPanel" updatemode="Conditional" xmlns:asp="#unknown">
            <triggers>
                <asp:asyncpostbacktrigger controlid="UpdateTimer" eventname="Tick" />
            </triggers>
            <contenttemplate>
                <asp:label runat="server" id="DateStampLabel" />
            </contenttemplate>
        </asp:updatepanel>

protected void UpdateTimer_Tick(object sender, EventArgs e)
{
    Response.Write("<script>alert('Time Over')</script>");
    Response.Redirect("result.aspx");
}

interval="5000" mean 5sec, you just need to modify this value 30min.
30min= 60000*30
