Properties, Arrays and ArrayLists using vb.net - vb.net

Question

In my code behind in my Web project I have a Property
Public Shared UserAttributes(2) As String
Public Property _UserAttributes(ByVal Index As Integer) As String
Get
Return UserAttributes(Index)
End Get
Set(value As String)
UserAttributes(Index) = value
End Set
End Property
And I also have an ArrayList declared as Friend
Friend UserParameters As New ArrayList
I call my property like that:
_UserAttributes(0) = "parameter1"
_UserAttributes(1) = "parameter2"
_UserAttributes(2) = "parameter3"
UserParameters.Add(UserAttributes)
_UserAttributes(0) = "parameter1,1"
_UserAttributes(1) = "parameter2,1"
_UserAttributes(2) = "parameter3,1"
UserParameters.Add(UserAttributes)
From the above code we may see the two pairs of Attributes having one text each one.
What I need now is:
After I add the three Attributes from my Property to my ArrayList
The second three Attributes of my property NOT to spoil the first one.
Which by now that they are doing
And finally I have two(2) _items in my ArrayList which they have the same text on each _item (which is the last one).
What I need is to write the second (or more) set of Attributes without spoiling the previous _items from ArrayList.

Answer 1

Finally I've made it to solve this puzzle as follows
One Property as ArrayList
Public Property _UserParameters As ArrayList
Get
Return UserParameters
End Get
Set(value As ArrayList)
UserParameters = value
End Set
End Property
Second Property as Array
Public Property _UserAttributes(ByVal Index As Integer) As String
Get
Return UserAttributes(Index)
End Get
Set(value As String)
UserAttributes(Index) = value
End Set
End Property
And from code behind I use this code:
Dim UserAttributes As New Hashtable
Dim key As Object = Nothing
Dim Param As Object = Nothing
Dim myList As New ArrayList
Dim item As Object = UserAttributes
UserAttributes.Add("UserId", "Parametr1")
UserAttributes.Add("UserName", "Parametr2")
UserAttributes.Add("UserMail", "Parametr3")
For Each item In UserAttributes
key = item.Key
Param = item.value
logHandler._UserParameters.Add(key & "^" & Param)
Next
myList.Add(logHandler.UserParameters.ToArray)
UserAttributes.Clear()
logHandler.UserParameters.Clear()
UserAttributes.Add("UserId", "Parametr1-1")
UserAttributes.Add("UserName", "Parametr2-1")
UserAttributes.Add("UserMail", "Parametr3-1")
For Each item In UserAttributes
key = item.Key
Param = item.value
logHandler._UserParameters.Add(key & "^" & Param)
Next
myList.Add(logHandler.UserParameters.ToArray)
The use of HashTable solves my issue, Along with the conversion from HashTable parameters to String
Which add them first to the ArrayList Property
And after that add them to the second ArrayList
And the result of these ArrayList I add it to a Pull Down menu control.
And Why I'm doing all that?
That is because I have many users with the same attributes as keys but deferent values
Good day to all, with many thanks.
