                if (line != null)

Correction:

......
           var query = from r in listRunner
                        //orderby r.Time
                        //select r;
                        select new {  r.Name, r.Time, r.Age };

            dataGridView1.DataSource = query.ToList();
   }

           var query = from r in listRunner
                        //orderby r.Time
                        //select r;

            dataGridView1.DataSource = query.ToList();
   }

Thanks a lot, it's working now.

But can you explain me why in this part of the code. There is no need to do that ?

private void Form1_Load(object sender, EventArgs e)
{
ObjectQuery<PersonName> personNameQuery = personNameContext.PersonName;
dgvPersonName.DataSource = personNameQuery;
dgvPersonName.Columns["ID"].Visible = false;
}
