Question

我创建了一个pos payform，但是当检测到相同的产品时，它将自动检测到它，并且它在增加数量行而不是最终价格行。这是我的代码：

private void Dodadivotabela()
{
    bool Found = false;

    if (dataGridView1.Rows.Count > 0)
    {
        foreach (DataGridViewRow row in dataGridView1.Rows)
        {
            if (Convert.ToString(row.Cells[0].Value) == txtBarajKod.Text)
            {
                row.Cells[3].Value =
                Convert.ToString(1 + Convert.ToInt64(row.Cells[3].Value));
                Found = true;
                break;
            }
        }
    }

    if (!Found)
    {
        price = float.Parse(txtCena.Text);
        quantity = float.Parse(txtKolicina.Text);
        finalprice = price *  quantity;

        var firstrow = txtBarajKod.Text;
        var secrow = txtNaziv.Text;
        var thirdrow = price;
        var forthrow = quantity;
        var fifthrow = finalprice;

        dataGridView1.Rows.Add(prvred, vtorred, tretred, cetvrtred, pettired);
    }
}

这是我对总行的计算：

 public void PresmetajTotal()
 {
     var vkp = 0;
     for (var i = 0; i < dataGridView1.Rows.Count; i++)
     {
         vkp += Convert.ToInt32(dataGridView1.Rows[i].Cells[4].Value);
         txtTotal.Text = vkp.ToString();
     }
 }

问题在于DGV中有4行，数量行已更新，但最终价格行保持不变。

Answer 1

当“ Found”为true时，如果“发现”为false，则似乎正在运行计算

If(Found){...}

而不是

If(!Found){...}

C＃计算总行数
