DataGridView如何只删除选中Checked的项啊?

C# code

                    for (int i = 0; i < dgv_DaoYouGuanLi.Rows.Count; i++)                    {                        if (dgv_DaoYouGuanLi.Rows[i].Cells["选择"].Selected==true)                        {                            string ZdyId = dgv_DaoYouGuanLi.Rows[i].Cells["ZdyId"].Value.ToString().Trim();                            string sql = B_XT.delDY(ZdyId);                            bool flag = TranClass.RunTran(sql);                            if (flag)                            {                                dgv_DaoYouGuanLi.Rows.RemoveAt(dgv_DaoYouGuanLi.Rows[i].Index);                            }                            else                            {                                MessageBox.Show("删除出现异常，请重新删除！", "错误提示", MessageBoxButtons.OK, MessageBoxIcon.Error);                            }                        }                    }

C# code

       for (int i = 0; i < dataGridView1.Rows.Count; i++)            {                DataGridViewCheckBoxCell chk = (DataGridViewCheckBoxCell)dataGridView1.Rows[i].Cells["选择"];                if ((Boolean)chk.EditedFormattedValue == true)                { string ZdyId = dgv_DaoYouGuanLi.Rows[i].Cells["ZdyId"].Value.ToString().Trim();                            string sql = B_XT.delDY(ZdyId);                            bool flag = TranClass.RunTran(sql);                            if (flag)                            {                                dgv_DaoYouGuanLi.Rows.RemoveAt(dgv_DaoYouGuanLi.Rows[i].Index);                            }                            else                            {                                MessageBox.Show("删除出现异常，请重新删除！", "错误提示", MessageBoxButtons.OK, MessageBoxIcon.Error);                            }                  }            }
[解决办法]
删除的话，到这来
for (int i = dataGridView1.Rows.Count-1; i >=0; i--)
