private void dataGridView1_CellClickobject sender DataGridViewCellEventArgs e if eColumnIndex == 11 dataGridView1Columns11ReadOnly = false;

要实现双击列后可以编辑值的效果，可以使用以下代码：

private void dataGridView1_CellDoubleClick(object sender, DataGridViewCellEventArgs e) { if (e.ColumnIndex == 11) { dataGridView1.Columns[11].ReadOnly = false; this.dataGridView1.BeginEdit(true); } }
