汇总列 [英] Summing columns

问题描述

你好.
我有带有"cCommonPrice"单元格的datagridview.我正在尝试label.text在此单元格中显示日期的总和

这是我的代码

hello.
i have datagridview with ''cCommonPrice'' cell. im trying to label.text show sum of date in this cell

this my code

private void btnSell_Click(object sender, EventArgs e)
{

    if (Program.myList.Contains(txtBarCode.Text))
    {
        SelectProduct(txtBarCode.Text);
    }

    for (int i = 0; i < dgvProducts.Rows.Count; i++)
    {
        decimal mon = 0;
        decimal comPrice;
        comPrice = (decimal)dgvProducts.Rows[i].Cells["cPrice"].Value;
        mon = comPrice;
        mon = mon + comPrice;
        lblPrice.Text = mon.ToString();
    }
    txtQuantity.ResetText();
    txtBarCode.ResetText();
}

但这不起作用
我需要帮助总结
我正在使用C#Winforms
datagridview源不是sql table

but it does not work
i need help for summing
Im using c# winforms
datagridview source is not sql table

推荐答案

我认为您的代码中存在一些问题.写这样的东西

I think there is some problem in your code. Write something like this

                decimal mon = 0;
                decimal comPrice;

for (int i = 0; i < dgvProducts.Rows.Count; i++)
            {
                try
                {
                comPrice = (decimal)dgvProducts.Rows[i].Cells["cPrice"].Value;
                mon += comPrice;
                }
                catch(Exception e)
                {}
            }
lblPrice.Text = mon.ToString();
