            List<int> list = new List<int>();
            for (int i=0;i<this.dataGridView1.SelectedRows.Count;i++)
            {
                int id = Convert.ToInt32(this.dataGridView1.SelectedRows[i].Cells["id"].Value);
                list.Add(id);
            }

Answer 2

            List<int> idList = new List<int>();
            foreach (DataRow dr in this.dataGridView1.SelectedRows)
            {
                idList.Add(int.Parse(dr["id"].ToString()));
            }

Answer 3

不好意思上面是 是错的，打DataRow 打习惯了。呵呵            List<int> idList = new List<int>();
            foreach (DataGridViewRow dr in this.dataGridView1.SelectedRows)
            {
                idList.Add(int.Parse(dr.Cells["id"].Value.ToString().Trim()));
            }            MessageBox.Show(idList[0].ToString());
