场景: C#中使用listView控件，实现动态添加，选中删除等操作.

        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
                    }
                }
            }
        }
