从另一个asp.net页访问列表对象

Question

I create a list ...

private static List<int[]> arrayList = new List<int[]>();

public static void Add(int Id, int Quantity)
{
    int[] buying = new int[] {Id, Quantity};
    arrayList.Add(buying);
}

Now ideally I want to access these list objects from another page, but its the first time I've really used lists and arrays so I don't know where to start?

any pointers?

Thanks

Answer 1

Save the objects's state from one page in Session:

Session["arrayList"] = arrayList

Access it in another Page:

if(Session["arrayList"]!=null)
 List<int[]> arrayList = Session["arrayList"] as List<int[]>;

Answer 2

1) Your List is private. U must do it public 2) Where is this code located?

Answer 3

You can expose another method like so

public static IEnumerable<int> MyArrayList()
{
     return arrayList;
}

This way you can only read the elements in the next page. If you want to add any elements then you can use your Add() method.
