ListView 绑定ImageList 的 有关问题.

ListView 绑定ImageList 的 问题......
下面这段代码有没有问题?为什么图标没有根据条件更换?盼高手指点....
  ListView listView1 = new ListView();
  listView1.Bounds = new Rectangle(new Point(10, 10), new Size(300, 200));
  listView1.View = View.LargeIcon;
  listView1.AllowColumnReorder = true;
  listView1.Alignment = ListViewAlignment.Default;
  listView1.Sorting = SortOrder.Ascending;
  for (int i = 100; i < 105; i++)
  {
  ListViewItem item = new ListViewItem(Convert.ToString(i), 0);
  listView1.Items.AddRange(new ListViewItem[] { item });
  ImageList imageListLarge = new ImageList();
  if (i<102)
  {
  imageListLarge.Images.Add(Bitmap.FromFile(@"F:\Test\Resources\a.ICO"));
  }
  else
  {
  imageListLarge.Images.Add(Bitmap.FromFile(@"F:\Test\Resources\b.ico"));
  }
  listView1.LargeImageList = imageListLarge;
  }
  this.Controls.Add(listView1);

------解决方案--------------------------------------------------------
ListViewItem item = new ListViewItem(Convert.ToString(i), 0); 
括号中的0就是你的ImageList的索引
而且你的ImageList要绑定到ListView
listview1.LargeImage=你的ImageList这是大图标
