Demo1：ListView基本操作和Group使用。
Code:

        private void Demo1_Click(object sender, EventArgs e)        {            //用于计算加载用时，建议使用Button的Click事件来观察            Stopwatch sp = new Stopwatch();            sp.Start();            lvContainer.BeginUpdate();            //设置ListView的相关属性            //imageListSource(ImageList)只有一张图片            lvContainer.View = View.SmallIcon;            lvContainer.SmallImageList = imageListSource;            lvContainer.GridLines = true;            lvContainer.FullRowSelect = true;            lvContainer.MultiSelect = false;            lvContainer.ShowGroups = true;  //显示分组            lvContainer.Alignment = ListViewAlignment.Top;     //ListViewItem排序规则，进行分组后建议使用top            //创建ListViewGroup            ListViewGroup listOdd = new ListViewGroup();            listOdd.Name = "奇数项";            listOdd.HeaderAlignment = HorizontalAlignment.Center;   //文本在列头居中            ListViewGroup listEven = new ListViewGroup();            listEven.Name = "偶数项";            listEven.HeaderAlignment = HorizontalAlignment.Left;     //左侧对齐            //强分组加入到ListView            lvContainer.Groups.Add(listOdd);            lvContainer.Groups.Add(listEven);            ;            //加载ListViewItem            for (int i = 0; i < 10; i++)            {                ListViewItem item = new ListViewItem();                item.ImageIndex = 0;                item.Text = i.ToString();                //将ListViewItem加入到Grop中                if (i % 2 == 0)                {                    listEven.Items.Add(item);                }                else                 {                    listOdd.Items.Add(item);                }                lvContainer.Items.Add(item);            }            //测试不进行分组的ListViewItem效果            lvContainer.Items.Add(new ListViewItem() { Text = "11", ImageIndex = 0 });            lvContainer.EndUpdate();            sp.Stop();            Console.WriteLine(sp.Elapsed.ToString());                     }
