文章发到这里了：Detecting a Client's screen resolution in ASP.NET by Serge Baranovsky 12/8/2002 Article source code: screenresolution.zipWhile there is no "native" to determine client bowser screen resolution in .NET Framework your ASP.NET application still can retrieve this information using little client-side JavaScript trick. Into your page (default.aspx in our case) we want to add code that will redirect to the screen detection page if it has never been done yet in the current session - Session["ScreenResolution"] is null default.aspx:<script runat="server" language="C#"> public void Page_Load(Object sender, EventArgs e){ if (Session["ScreenResolution"] == null) { // Session variable is not set // Redirect to the screen resolution detection script Response.Redirect("detectscreen.aspx"); } else { // Session variable is set // Display it on the page screenresolution.Text = Session["ScreenResolution"].ToString(); } } </script> <HTML> <BODY> User screen resolution: <asp:label id="screenresolution" runat="server">undetected</asp:label> </BODY> <HTML> The screen resolution detection script (detectscreen.aspx) determines the client screen height, width, color depth and redirects back to the default.aspx page detectscreen.aspx:<script runat="server" language="C#"> public void Page_Load(Object sender, EventArgs e){ if (Request.QueryString["action"] != null) { // store the screen resolution in Session["ScreenResolution"] // and redirect back to default.aspx Session["ScreenResolution"] = Request.QueryString["res"].ToString(); Response.Redirect("default.aspx"); } } // JavaScript code below will determine the user screen resolution // and redirect to itself with action=set QueryString parameter </script> <HTML><BODY> <script language="javascript"> res = "&res="+screen.width+"x"+screen.height+"&d="+screen.colorDepth top.location.href="detectscreen.aspx?action=set"+res </script> </BODY></HTML> Here is yet another script that will be useful while testing the two above - it resets the Session["ScreenResolution"] variable to null reset.aspx:<script runat="server" language="C#"> public void Page_Load(Object sender, EventArgs e){ Session["ScreenResolution"] = null; } </script> Session["ScreenResolution"] has been reset to <i>null</i>
将javascript获得的时间赋给一个hidden
<INPUT type="hidden" id="aaa" name="aaa" value=时间>
然后在服务器端取出
Request.Form["aaa"]

Article source code: screenresolution.zipWhile there is no "native" to determine client bowser screen resolution in .NET Framework your ASP.NET application still can retrieve this information using little client-side JavaScript trick. Into your page (default.aspx in our case) we want to add code that will redirect to the screen detection page if it has never been done yet in the current session - Session["ScreenResolution"] is null default.aspx:<script runat="server" language="C#"> public void Page_Load(Object sender, EventArgs e){ if (Session["ScreenResolution"] == null) {
// Session variable is not set
// Redirect to the screen resolution detection script
Response.Redirect("detectscreen.aspx");
} else {
// Session variable is set
// Display it on the page
screenresolution.Text = Session["ScreenResolution"].ToString();
}
} </script> <HTML>
<BODY>
User screen resolution: <asp:label id="screenresolution" runat="server">undetected</asp:label>
</BODY>
<HTML>
The screen resolution detection script (detectscreen.aspx) determines the client screen height, width, color depth and redirects back to the default.aspx page detectscreen.aspx:<script runat="server" language="C#"> public void Page_Load(Object sender, EventArgs e){ if (Request.QueryString["action"] != null) {
// store the screen resolution in Session["ScreenResolution"]
// and redirect back to default.aspx
Session["ScreenResolution"] = Request.QueryString["res"].ToString();
Response.Redirect("default.aspx");
}
}
// JavaScript code below will determine the user screen resolution
// and redirect to itself with action=set QueryString parameter </script> <HTML><BODY>
<script language="javascript">
res = "&res="+screen.width+"x"+screen.height+"&d="+screen.colorDepth
top.location.href="detectscreen.aspx?action=set"+res
</script>
</BODY></HTML>
Here is yet another script that will be useful while testing the two above - it resets the Session["ScreenResolution"] variable to null reset.aspx:<script runat="server" language="C#"> public void Page_Load(Object sender, EventArgs e){ Session["ScreenResolution"] = null; } </script> Session["ScreenResolution"] has been reset to <i>null</i>
然後再把'var'=textbox.text
主意你用的是html 控件的時候要加上 runat="server"
var d,t;
d = new Date();
t = d.getTime();第二步，对客户端的hidden控件付值
<input type='hidden' name='hDate'>
<script language='javascript'>
document.all['hData'].value = t;
</script>第三步，在服务器段获取这个值
DateTiem dt;
dt = DateTime.Parse( Request.Params["hData"] );
