这是别人写的。什么意思啊。listViewHall.Items.Add（string key，string text， int imagekey）方法怎么用的啊。key项的名称。text项的文本。imageKey要为该项显示的图像的键。看不懂。那些图片该放哪里的

Answer 1

图片放在ImageList中，指定ListView的LargeImageList为此ImageList，然后指定每一项的ImageKey或ImageIndex为对应的值。

Answer 2

ListViewItemCollection.Add() 
用指定键，文本和图像创建一个项并添加到结合
imagelist中索引
