Implementing Tuples

I am very new to VB.net.  

In the following code I am trying to implement tuples.  You'll notice in the SQL clause that I pulled [System Name] and Agency ID and I want them to appear as AgencyID &  "-" & [System Name]  in a dropdown list.  I'm figuring that I will use tuples in lstProfiles in order to create the list.  What changes do I need to make in order to make that happen?

 Public Function fetchActiveProfiles() As List(Of String)
        Dim lstProfiles As New List(Of String)

        Dim sqlCmd As String
        sqlCmd = ""
        sqlCmd = sqlCmd & " select [System Name],AgencyID"
        sqlCmd = sqlCmd & " from tblOrgProfile"
        sqlCmd = sqlCmd & " Where Active = 1"
        sqlCmd = sqlCmd & " order by [System Name]"

        Try
            Using con As New SqlConnection(GetConnectionString)
                con.Open()

                Using cmd As New SqlCommand(sqlCmd, con)
                    cmd.CommandType = CommandType.Text

                    Using rs As SqlDataReader = cmd.ExecuteReader()
                        If Not rs.HasRows Then
                            Return lstProfiles
                        End If

                        'rs.NextResult()
                        While rs.Read
                            lstProfiles.Add(rs.GetString(0))
                        End While
                    End Using
                End Using

                con.Close()
            End Using
        Catch ex As Exception
            Throw New DatabaseConnectionException()
        End Try

        Return lstProfiles
    End Function

Very good solution and that works well.  The purpose of me asking how to do this using tuples was mainly for learning purposes so if its possible for an expert to provide how I might do that using .NET that would be most helpful.
