C# Windows DataGridView 判斷CheckBox 選取的方法

最近在做一個C# winform的小東西,在用到向DataWindow 中添加新行.實現方法是右擊菜單後彈出一表單,新表單上有一個DataGridView ,第一列是個DataGridViewCheckBoxColumn列.要求是選中checkbox的行添加到父表單資料來源中.現就判斷哪些有選中的

foreach (DataGridViewRow dr in this.dataGridView1.Rows)
            {
                try
                {
                    //DataGridViewCheckBoxCell cbx = (DataGridViewCheckBoxCell)dr.Cells[0];
                    //if ((bool)cbx.FormattedValue)
                    if(dr.Cells[0].Selected)
                    {
                        arrShiftCode.Add(dr.Cells[1].Value);
                        arrShiftGroup.Add(dr.Cells[2].Value);
                    }
                }
                catch (Exception ex)
                {
                    MessageBox.Show(ex.Message);
                }            }

以上是一開始這樣寫的,發現選中了多個,始終只有最後一個是True,其他的都是False.最後經查資料有如下寫法即可      

            foreach (DataGridViewRow dr in this.dataGridView1.Rows)
            {
                try
                {
                    DataGridViewCheckBoxCell cbx = (DataGridViewCheckBoxCell)dr.Cells[0];
                    if ((bool)cbx.FormattedValue)
                    {
                        arrShiftCode.Add(dr.Cells[1].Value);
                        arrShiftGroup.Add(dr.Cells[2].Value);
                    }
                }
                catch (Exception ex)
                {
                    MessageBox.Show(ex.Message);
                }
            }
