通过查询字符串参数更改会话变量
|
我们在www.CrownCountry.com/calendar/index.aspx上有一个日历。标头控件包含一个下拉框和一个按钮，可让您选择/过滤显示的类别。我相信这是通过会话变量来处理的。我们希望能够从其他站点链接并传递查询字符串，该查询字符串将使我们能够发送到已经显示/重定向了所选类别的站点。

if ( System.Web.HttpContext.Current.Session[\"category\"] != null ) HMenucategories.Value = (string)System.Web.HttpContext.Current.Session[\"category\"];中。在上面的代码之前的某处添加以下代码。if(!String.IsNullOrEmpty(Request.QueryString[\"category\"])) Session.Add(\"category\", Request.QueryString[\"category\"]);殿虫
上的GET值并将其分配给会话变量？ 因此，无需查看您的代码（每个值）：void Page_Init(object sender,EventArgs e) { Session[\"value\"] = Request.Querystring[\"value\"]; }
