//Global.asax

Hi,
//Global.asax

public class Global : System.Web.HttpApplication
{
        public static int value = 0;
       // all other functions....
}

假设您在Menu.aspx页面中有链接。

Suppose you have your links in Menu.aspx page.

<form id="form1" runat="server">
    <div>
        <asp:hyperlink id="hyp" runat="server" navigateurl="~/Check.aspx" text="Clickme" onclick="redirect(event,this)" xmlns:asp="#unknown"></asp:hyperlink>
        <asp:hyperlink id="hyp1" runat="server" navigateurl="~/Check1.aspx" text="Clickme1" onclick="redirect(event,this)" xmlns:asp="#unknown"></asp:hyperlink>
        <asp:hyperlink id="hyp2" runat="server" navigateurl="~/Check2.aspx" text="Clickme2" onclick="redirect(event,this)" xmlns:asp="#unknown"></asp:hyperlink>
    </div>
    <script type="text/javascript">
        function redirect(e,a) {
            e.preventDefault();
            var url = a.href;

.ajax（{
type： POST，
url： < span class =code-string> Menu.aspx / SetValue，
data： {'网址'：' +网址+ '}，
contentType： application / json; charset = utf-8，
dataType： json，
成功： function （data）{
window 。 location .assign（url）;
}，
失败：功能（数据）{
}
}）;
}
< / 脚本 >
< / form >

.ajax({ type: "POST", url: "Menu.aspx/SetValue", data: "{ 'URL': '" + url + "' }", contentType: "application/json; charset=utf-8", dataType: "json", success: function (data) { window.location.assign(url); }, failure: function (data) { } }); } </script> </form>

//现在你的代码落后

// now your code behind

[WebMethod]
        public static void SetValue(string URL)
        {
            string path = new Uri(URL).AbsolutePath;
            // set global value according to redirect url
            switch (path)
            { 
                case "/Check.aspx":
                    Global.value = 1;
                    break;
                case "/Check1.aspx":
                    Global.value = 2;
                    break;
                case "/Check2.aspx":
                    Global.value = 3;
                    break;
            }
        }

//在此示例中您重定向到页面之一假设Check.aspx

// one of your redirect to page in this example suppose Check.aspx

protected void Page_Load(object sender, EventArgs e)
       {
           if (!IsPostBack)
           {
               if (Global.value != 1)
               {
                   Response.Redirect("Menu.aspx");
               }
               else
               {
                   //if you strictly about this rule then make global value again 0.
                   //Global.value = 0;
               }
           }
       }

希望它可以帮到你。

谢谢。
