Need to sort a diction by the String Keys?


' Get list of keys.
 Dim keys As List(Of String) = EMailSessionTotals.Keys.ToList

 ' Sort the keys.

 ' Loop over the sorted keys.
 Dim str As String
 For Each str In keys
 _counter += 1
 Dim _li As New ListViewItem
 _li.Text = str
 If _counter Mod 2 = 0 Then
 _li.BackColor = Color.LightGray
 End If
