如何给listview加一行

Question

 List<crm> ls =从数据里弄出来的crm集合
 //crm实体里面有id，name，date，price
 foreach (crm p in ls)
     {
                AddProduct(p);
      }   //循环添加实体到listview1
        private void AddProduct(crm p)
        {
            ListViewItem lvi = this.listView1.Items.Add(p.Id.ToString());
          
            lvi.SubItems.Add(p.Name);
            lvi.SubItems.Add(Convert.ToDateTime(p.Date.ToString()).ToString("yyyy-MM-dd"));
            lvi.SubItems.Add(p.Price.ToString());        }我想实现的，在price列的最后一行，加一行，就是price列的总和怎么实现啊？给我代码呗，我试过了，好乱啊

Answer 1

ListViewItem lvi = new ListViewItem();
lvi.Subitems.Add("");
lvi.Subitems.Add("");
lvi.Subitems.Add(sum.ToString());
listView1.Items.Add(lvi);

Answer 2

    float sum=0.0; 
    foreach (crm p in ls)
     {
                AddProduct(p);
                sum+=p.price;
      } 
      AddProduct((cmp)null)
   //循环添加实体到listview1
        private void AddProduct(crm p)
        {
            ListViewItem lvi;
            if(p!=null)
            {
               lvi = this.listView1.Items.Add(p.Id.ToString());
          
               lvi.SubItems.Add(p.Name);
               lvi.SubItems.Add(Convert.ToDateTime(p.Date.ToString()).ToString("yyyy-MM-dd"));
               lvi.SubItems.Add(p.Price.ToString());
            }
            else
            {
                lvi = this.listView1.Items.Add(string.Empty);
          
                lvi.SubItems.Add(string.Empty);
                lvi.SubItems.Add(string.Empty);
                lvi.SubItems.Add(sum.ToString());            }        }

ListViewItem lvi = new ListViewItem();
lvi.Subitems.Add("");
lvi.Subitems.Add("");

int sum=0;
foreach (crm p in ls)

ListViewItem li = new ListViewItem();
li.Text="";
li.SubItems.Add("");
ListView1.Items.Add(li);

Answer 5

用listview作这个ms效果不太好吧，个人认为放到一个label里，随便安排一个位置，不要放到listview里面
