How to store SortedList in Session or Cache.

Imports System.Collections

Dim lst As New SortedList()  
lst.Add("Key1","ValueA")  
lst.Add("Key2","ValueB")  
Session("SortedList") = lst

'To convert Session again into SortedList,we will write below code:-
Dim sort_lst_obj As SortedList = CType(Session("SortedList"),SortedList)

'To access value from SortedList
Dim str_value1 As String = sort_lst_obj("Key1")
Dim str_value2 As String = sort_lst_obj("Key2")
