how do I select first ischecked property of list to true and rest false

Question

How do I select first ischecked property of list to true and rest false.

unitnames_list = (from DataRow row in dt_get_unitnames.Rows
                  select new tb_units
                  {
                      UnitID = Convert.ToInt32(row["UnitID"].ToString()),
                      UnitName = row["UnitName"].ToString(),
                      ischecked = true
                  }).ToList();

`ischecked = false`, then `unitnames_list[0].ischecked = false;` — , Jan 31 '17 at 06:18
And I assume you corrected my typo - `unitnames_list[0].ischecked = true;` (not `false`) :) — , Jan 31 '17 at 06:25

Following How do you add an index field to Linq results, one possible solution would be

unitnames_list = dt_get_unitnames.Rows.Select((row, index) =>
    new tb_units
    {
        UnitID = Convert.ToInt32(row["UnitID"].ToString()),
        UnitName = row["UnitName"].ToString(),
        ischecked = index == 0
    }).ToList();
