c# - 使用 View.Details 用 ImageList 填充 ListView

Question

将图标加载到我的列表视图时出现问题。我可以让图像在大视图中工作，但不能在细节上工作，不太确定我做错了什么。

private void CreateList()
{
    listView1.View = View.Details;

    listView1.Columns.Add("Icon", -2, HorizontalAlignment.Center);

    listView1.Columns.Add("Name", -2, HorizontalAlignment.Left);

    imageList1.ImageSize = new Size(32, 32);

    for (int i = 0; i < subKeys.Length; i++)
    {
        if (subKeys[i].Contains("App"))
        {
            imagePath = subKeys[i];

            if (System.IO.File.Exists(imagePath))
            {
                imageList1.Images.Add(Image.FromFile(imagePath));
            }

            numberOfImages++;
        }
    }

    listView1.StateImageList = this.imageList1;
}

Answer 1

改变

listView1.StateImageList = this.imageList1;

到

listView1.SmallImageList = this.imageList1;

并确保为每个 ListItem设置ImageIndex、 或属性。ImageKey

listItem.ImageIndex = 0; // or,
listItem.ImageKey = "myImage";

Answer 2

试试这个代码：

        DirectoryInfo dir = new DirectoryInfo(@"c:\myPicutures"); //change and get your folder
        foreach (FileInfo file in dir.GetFiles())
        {
            try
            {
                this.imageList1.Images.Add(Image.FromFile(file.FullName));
            }
            catch{
                Console.WriteLine("This is not an image file");
            }
        }
        this.listView1.View = View.LargeIcon;
        this.imageList1.ImageSize = new Size(32, 32);
        this.listView1.LargeImageList = this.imageList1;
        //or
        //this.listView1.View = View.SmallIcon;
        //this.listView1.SmallImageList = this.imageList1;

        for (int j = 0; j < this.imageList1.Images.Count; j++)
        {
            ListViewItem item = new ListViewItem();
            item.ImageIndex = j;
            this.listView1.Items.Add(item);
        }

您甚至可以添加第二列，并“添加”文件名。
