自定义类中的图像不填充图像列表

Question

我尝试使用包含另一个包含图像的类列表的类，通过图像列表填充列表视图。

专辑类：

public class Camera
{
    List<Photo> _photos = new List<Photo>();
    string _title = string.Empty;

    public List<Photo> Photos
    {
        get
        {
            return this._photos;
        }
        set
        {
            this._photos = value;
        }
    }

照片类

public class Photo
{

    Image _photo = null;
    String _description = string.Empty;


    public Image PhotoImage
    {
        get
        {
            return this._photo;
        }
        set
        {
            this._photo = value;
        }
    }

相关代码

public Form1()
    {
        InitializeComponent();

        btnCapture.Enabled = false;

        this.listAlbum.View = View.LargeIcon;
        this.imageList1.ImageSize = new Size(64, 48);
        this.listAlbum.LargeImageList = this.imageList1;

        foreach (EncoderDevice edv in EncoderDevices.FindDevices(EncoderDeviceType.Video))
        {
            comboCameraSelect.Items.Add(edv.Name);
        }            
    }
private Image GetScreenShot()
    {
        Image temp = null;

        using (Image screenImage = new Bitmap(panelPreview.Width, panelPreview.Height))
        {
            using (Graphics g = Graphics.FromImage(screenImage))
            {                    
                Rectangle rectanglePanelVideoPreview = panelPreview.Bounds;
                Point sourcePoints = panelPreview.PointToScreen(new Point(panelPreview.ClientRectangle.X, panelPreview.ClientRectangle.Y));
                g.CopyFromScreen(sourcePoints, Point.Empty, rectanglePanelVideoPreview.Size);
            }

            temp = screenImage;
        }

        return temp;

    }

public void btnCapture_Click(object sender, EventArgs e)
    {
        Photo p = new Photo();
        p.PhotoImage = GetScreenShot();            

        album.Photos.Add(p);

        this.imageList1.Images.Add(p.PhotoImage);

        ListViewItem item = new ListViewItem();
        item.ImageIndex = j;
        item.ImageKey = j.ToString();
        this.listAlbum.Items.Add(item);

        j = (j + 1);
    }

当程序到达

时

this.imageList1.Images.Add(p.PhotoImage);

它抛出一个异常，说参数无效，尽管它是一个图像。

列表视图似乎可以获得索引，因为滚动条在多个循环后出现，但没有显示任何拇指，也没有任何可选项。

非常感谢任何建议。

感谢。
