Using sql to load a datatable and create a dictionary

    Dim SalesRep As New System.Collections.Generic.Dictionary(Of String, String)(StringComparer.InvariantCultureIgnoreCase)
    Using tbl As New Data.DataTable("SalesRep")
        SqlCommand.CommandText = "Select Initial,FullName from QB_SalesRep"
        tbl.Load(SqlCommand.ExecuteReader())
        ' --- Option ONE use the array to iterate
        Array.ForEach(tbl.Rows.Cast(Of Data.DataRow).ToArray(),
                      Sub(f)
                          SalesRep.Add(f.ItemAsString("Initial"), f.ItemAsString("FullName"))
                      End Sub)
        ' --- Option TWO use plain linq to create the dictionary
        SalesRep = tbl.Rows _
            .Cast(Of Data.DataRow) _
            .AsEnumerable() _
            .ToDictionary(Function(f) f.Item("Initial").toString(), Function(f) f.Item("FullName").toString)
