场景: C#中使用listView控件，实现动态添加，选中删除等操作.

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22

private void addButton_Click(object sender, EventArgs e) {      string item1Str = coutNumber.ToString(); //第一列文本      string item2Str = coutNumber.ToString(); //第二列文本      this .listView1.Items.Add( new ListViewItem( new string[] { item1Str, item2Str })); //添加一行      coutNumber++; //listView的行数递增 }   private void delButton_Click(object sender, EventArgs e) {      foreach (ListViewItem item in listView1.Items)      {          if (listView1.SelectedItems.Contains(item))          {              int indexDel = listView1.Items.IndexOf(listView1.FocusedItem);              if (listView1.SelectedItems.Count != 0 )              {                 listView1.Items.RemoveAt(indexDel); //删除              }          }      } }
