If what you want is to show an image for your ListViewItem, then you need to create an ImageList, fill it with images, assign the ImageListto the ListViewand then tell every ListViewItemwhich image from the list to use:
如果你想要的是显示图像为您ListViewItem的，那么你需要创建一个ImageList中，用图像填充它，将分配的ImageList到ListView控件，然后告诉每一个ListViewItem其图像从列表中使用：
var listView = new ListView();
// create image list and fill it
var imageList = new ImageList();
imageList.Images.Add("itemImageKey", image);
// tell your ListView to use the new image list
listView.LargeImageList = imageList;
// add an item
var listViewItem = listView.Items.Add("Item with image");
// and tell the item which image to use
listViewItem.ImageKey = "itemImageKey";
You can read more about ListViewItem and how to set/use images in this MSDN articleor in this MSDN tutorial.

};
ImageList il = new ImageList();
DownloadImagesFromWeb(address, il);
il.ImageSize = new Size(32, 32);
int count = 0;
listView1.LargeImageList = il;
List<string> names = new List<string>() { "1", "2", "3", "4" };
foreach (string s in names)
{
ListViewItem lst = new ListViewItem();
lst.Text = s;
lst.ImageIndex = count++;
listView1.Items.Add(lst);
}
}
private void DownloadImagesFromWeb(List<string> adress, ImageList il)
{
foreach (string img in adress)
{
System.Net.WebRequest request = System.Net.WebRequest.Create(img);
System.Net.WebResponse resp = request.GetResponse();
System.IO.Stream respStream = resp.GetResponseStream();
Bitmap bmp = new Bitmap(respStream);
respStream.Dispose();
il.Images.Add(bmp);
}
}
This is an option for you not to copy each image manualy to your computer, instead you provide the url and place that image in a new bitmap and add to the list.
这是一个选项，您无需手动将每个图像复制到您的计算机，而是提供 URL 并将该图像放置在新位图中并添加到列表中。
