获取总行数：dataGridView1.Rows.Count;

获取当前选中行索引：int i = this.dataGridView1.CurrentRow.Index;

获取当前选中列索引：int j = this.dataGridView1.CurrentCell.ColumnIndex

selecteRows.Add(r);

}

}if (selectedRowsIndex.Count > 1)

{

if (MessageBox.Show("确定删除" + selectedRowsIndex.Count.ToString() + "行数据吗?", "删除前确认", MessageBoxButtons.YesNo) == DialogResult.Yes)

{

foreach (DataGridViewRow r in selecteRows)
