将数组存储到会话 [英] Storing array to session

问题描述

如何在会话中添加数组？有办法吗？继承我的代码：

 protected void CompetencyRetrieve（object sender，EventArgs e）
 {
 int index = Convert。 ToInt32（maxindex.Text）; // ERROR HERE 
 
 DropDownList box1 =（DropDownList）Gridview1.Rows [index] .Cells [1] .FindControl（DropDownList1）; 
 DropDownList box2 =（DropDownList）Gridview1.Rows [index] .Cells [2] .FindControl（DropDownList2）; 
 DropDownList box3 =（DropDownList）Gridview1.Rows [index] .Cells [3] .FindControl（DropDownList3）; 
 
 var Trainings = DataService.Instance.getTraining（box2.Text，box1.Text）; 
 if（Trainings.Rows.Count！= 0）
 {
 box3.DataSource = Trainings; 
 box3.DataTextField =ProgramsDesc; 
 box3.DataValueField =Programs_id; 
 box3.DataBind（）; 
 
 //此处会话
 
} 
其他
 {
 box3.Items.Clear（）; 
} 
 
 
} 
 

每次这个功能触发器，将添加数组的条目，然后存储在会话中。任何帮助？

存储所有物品数组。

  string  [] a =  new   string  [] {  a，  b，  c}; 
会话[  values] = a; 

在下一页中，您可以像这样检索它。

  string  [] a =（ string  []）会话[ 值 

Hi,

how can I add an array to a session? is there a way to do it? heres my code:

protected void CompetencyRetrieve(object sender, EventArgs e)
   {
       int index = Convert.ToInt32(maxindex.Text); // ERROR HERE

           DropDownList box1 = (DropDownList)Gridview1.Rows[index].Cells[1].FindControl("DropDownList1");
           DropDownList box2 = (DropDownList)Gridview1.Rows[index].Cells[2].FindControl("DropDownList2");
           DropDownList box3 = (DropDownList)Gridview1.Rows[index].Cells[3].FindControl("DropDownList3");

           var Trainings = DataService.Instance.getTraining(box2.Text, box1.Text);
           if (Trainings.Rows.Count != 0)
           {
               box3.DataSource = Trainings;
               box3.DataTextField = "ProgramsDesc";
               box3.DataValueField = "Programs_id";
               box3.DataBind();

               //session here

           }
           else
           {
               box3.Items.Clear();
           }


   }

each time that this function triggers, an entry to the array will be added, then stored inside a session. any help?

解决方案

Try this
may be this will help you..
To store all items of the array.

string[] a = new string[]{"a","b","c"};
Session["values"] = a;

And in the next page, you can retrieve it like this.

string[] a = (string[])Session["values"]
