试图了解通过会话传输列表框值/项目.

Trying to understand transfering listbox values/items with sessions.(试图了解通过会话传输列表框值/项目.)

问题描述

在我的第一页我有两个列表框 Movies 和 Snacks

On my first page I have two listboxes for Movies and Snacks

Movies 称为 lbDisplay，Snacks 称为 lbSelected.

我目前正在使用具有以下代码的转到购物车"功能:

I am currently using a "Go to cart" function that has the following code:

Session["lbSelectedMovies"] = lbDisplay;
Session["lbSelectedSnacks"] = lbSelected;
Response.Redirect("RingU6POSReview.aspx");

在重定向页面上，我希望将给定值传输到的两个列表框称为 lbRvMovies 和 lbRvSnacks

on the redirected page the two listboxes that I want the given values to transfer to are called lbRvMovies and lbRvSnacks

页面名为RingU6POSReview.aspx

谁能帮助我了解在重定向客户时如何传递值?

Can anyone help me understand how to transfer the values when I redirect the customer?

推荐答案

在第二页上说你有另一个列表框(比如 ListBox1)，你想给它分配传递的值，然后使用下面的任何一个.3种方法:

On the 2nd page say you have another list box (say ListBox1) to which you want to assign the passed values then use the any one of the foll. 3 methods:

   ListBox  ListBox1 = null;

        ListBox1 = Session["lbSelectedMovies"] as ListBox;

或

ListBox ListBox1 = new ListBox();       
    foreach (ListItem Item in ((ListBox)(Session["lbSelectedMovies"])).Items)
    {          
        ListBox1.Items.Add(new ListItem(Item.Text, Item.Value));
    }

或

ListBox1.Items.AddRange((ListItem[])Session["lbSelectedMovies"]);
