Answer 1

haven't tried it outside of just making sure it builds, runs, and seems to populate the datatable fine.

        var dataTable = new DataTable();
        dataTable.Columns.Add("Col1", list1.GetType().GetGenericArguments().First());
        dataTable.Columns.Add("Col2", list2.GetType().GetGenericArguments().First());
        dataTable.Columns.Add("Col3", list3.GetType().GetGenericArguments().First());
        dataTable.Columns.Add("Col4", list4.GetType().GetGenericArguments().First());

        // assumes they all match on count
        for (int i = 0; i < list1.Count; i++)
        {
            dataTable.Rows.Add(list1[i], 
                               list2[i],
                               list3[i],
                               list4[i]);
        }
