Not about most efficient but for an alternative, you can use the Select method:

DataRow[] rows= dataTable.Select();

And now you have an IEnumerable of rows. This method may help someone:

public static List ConvertDataTableToGenericList(DataTable dt)
{
     var columnNames = dt.Columns.Cast()
            .Select(c => c.ColumnName)
            .ToList();

     var properties = typeof(T).GetProperties();
     DataRow[] rows= dt.Select();
     return rows.Select(row =>
     {
          var objT = Activator.CreateInstance();
          foreach (var pro in properties)
          {
              if (columnNames.Contains(pro.Name))
                   pro.SetValue(objT, row[pro.Name]);
          }

          return objT;
     }).ToList();
}
