推荐答案

复选框有一个酒店IsChecked属性。您可以使用它来计算您的定价值。

对于那些检查的复选框，您只能为它们执行价格计算。 U可以使用此属性来区分已选中和未选中的复选框。

Checkbox have a property IsChecked property. U can use it to calculate your pricing values.
For those check boxes which are check u can perform price calculation for them only. U can use this property to differentiate between check boxes which are checked and which are not.

DataGridView包含DataGridViewRows集合。集合中的每一行都是 DataGridViewRow [ ^ ]。



要获得所选行的总和，您需要遍历行集合：

DataGridView contains DataGridViewRows collection. Each row in the collection is DataGridViewRow[^].

To get the total sum of selected rows, you need to iterate through the collection of rows:

    private void button1_Click(object sender, EventArgs e)
    {
        DataGridViewCell dc = null;
        DataGridViewCheckBoxCell cbx = null;
        double mySum = 0;
        string s = string.Empty;
        foreach (DataGridViewRow dr in dataGridView1.Rows)
        {
            dc = dr.Cells[2];
            cbx = (DataGridViewCheckBoxCell)dc;
            if (Convert.ToBoolean(cbx.Value))
            {
                mySum += double.Parse(dr.Cells[0].Value.ToString());
            }
        }
        s = String.Format("Total sum: {0}", mySum.ToString());
        MessageBox.Show(s);
    }
}
