问题描述

我已将哈希表存储在会话变量中，现在我想在不同标签的其他页面上检索其数据。

i have stored hash table in a session variable now i want to retrieve its data on other page in different labels.

推荐答案

请参阅：http://forums.asp.net/t/1353450.aspx [ ^ ]请记住，不应将大数据存储到会话中。

See this : http://forums.asp.net/t/1353450.aspx[^] Remember, you should not store large data into session.

As hastable存储keyvaluespair值，你必须将keyvalue对存储在hastable中。

请参考以下示例...在此示例中，我将数据存储在一个页面的会话变量中，并将其访问到另一个页面。



希望这会对你有所帮助。



default.aspx.cs

As the hastable stores the keyvaluespair values, you have to store keyvalue pair in hastable.
refer the following example for the same.. in this example i am storing data in session variable from one page and access it in to another page.

hope this will help you.

default.aspx.cs

public partial class _Default : System.Web.UI.Page
   {
       protected void Page_Load(object sender, EventArgs e)
       {

           try
           {
               Dictionary<int, string> dict = new Dictionary<int, string>();
               dict.Add(1, "value1");
               dict.Add(2, "value2");
               Hashtable ht = new Hashtable(dict);
               Session["data"] = ht;
               Response.Redirect("default2.aspx", false);
           }
           catch (Exception)
           {
               throw;
           }
       }
   }

default2.aspx。 cs

default2.aspx.cs

public partial class default2 : System.Web.UI.Page
   {
       protected void Page_Load(object sender, EventArgs e)
       {
           if (Session["data"] != null)
           {
               Hashtable ht = Session["data"] as Hashtable;


           }
       }
   }
