dim arr(5,5) as string

Label1.Text = arr(1,1).tostring

I have an object that has a property called GroupID with is a 2 dimensional array

    Public Property GroupID() As Integer(,)
        Get
            Return Me.mint_groupID
        End Get
        Set(ByVal Value As Integer(,))
            Me.mint_groupID = Value
        End Set
    End Property

objEmployee.GroupID  = GetEmployeeGroupAnRole() As Integer(,)

That fucntion returns a value pair collection of (GroupID, RoleID) the user's belong to

So practically I am getting somethin like this

(0,0) = 222
(0,1) = 3
(1,0) = 232
(1,1) = 1
(,)
(,)
'
'
'
etc...

Let me know if you need further detail

(0,0) = 222
(0,1) = 3
(1,0) = 232
(1,1) = 1
(,)
(,)

if you are not doing arithemetic on the 'numbers', then you would be better off to treat them as strings

    Dim mint_groupID() as String(,)

    Public Property GroupID() As String(,)
        Get
            Return Me.mint_groupID
        End Get
        Set(ByVal Value As String(,))
            Me.mint_groupID = Value
        End Set
    End Property

objEmployee.GroupID  = GetEmployeeGroupAnRole() As String(,)

What I need is this loop to work using a 2 dimensional array

           For i = 0 To UBound(cUser.GroupID, 1) - 1
                For j = 0 To UBound(cUser.GroupID, 1) - 1
                    Me.lblGroup.Text = "(" & cUser.GroupID(i, 0).ToString & ", " & cUser.GroupID(0, j) & ")" & "<br/>"
                Next
            Next

Question:
How do i loop to display the content of the array?
