总和列表查看小数点

Question

我需要一些帮助来总结小数点。

我使用下面的代码来显示一个列表视图，并希望在列表视图的最后一行显示销售价格的总和。

foreach (Stock c in stock) 
{ 
    string[] subitems = new string[4]; 
    subitems[0] = c.ID.ToString(); 
    subitems[1] = c.ItemDescription; 
    subitems[2] = "£" + c.PurchasePrice; 
    subitems[3] = "£" + c.SalePrice; 

    ListViewItem listItem = new ListViewItem(subitems); 
    SalelistView.Items.Add(listItem); 

    ItemNumberTofFnd.Text = ""; 
} 

如何显示总销售价格？

我试过decimal T += c.SalePrice，但我很不确定，因为我之前没有做过这种事情。

像这样的东西？

decimal total; 
foreach (Stock c in stock) 
{ 
    string[] subitems = new string[4]; 
    subitems[0] = c.ID.ToString(); 
    subitems[1] = c.ItemDescription; 
    subitems[2] = "£" + c.PurchasePrice; 
    subitems[3] = "£" + c.SalePrice; 

    total += c.SalePrice; 

    ListViewItem listItem = new ListViewItem(subitems); 
    SalelistView.Items.Add(listItem); 

    ItemNumberTofFnd.Text = ""; 
} 
SalelistView.Items.Add("Total " + total);
