.net 如何在Windows气泡通知中显示图像？

是否可以在Windows气泡通知中显示自定义图像/图标？net framework中的控件支持气泡通知，但它只允许默认图标，如信息、错误等

---

如果NotifyIcon不支持此功能，是否有其他API.net框架允许使用自定义图像进行通知？

未经测试，但您可以更改图标，希望这有帮助

notificationIcon.Icon =  new Icon(Properties.Resources.ResourceManager.GetStream("<Image Location From root>"));

notificationIcon.Icon=新图标（Properties.Resources.ResourceManager.GetStream（“”）；

找到了答案。Windows API支持自定义图标，但托管的.net界面非常简单。Win32 api接受一个结构。此结构具有设置自定义图标的字段

    public enum NotifyFlags
    {
        NIF_MESSAGE = 0x01, NIF_ICON = 0x02, NIF_TIP = 0x04, NIF_INFO = 0x10, NIF_STATE = 0x08,
        NIF_GUID = 0x20, NIF_SHOWTIP = 0x80, NIF_REALTIME = 0x40,
    }

    public enum NotifyCommand { NIM_ADD = 0x0, NIM_DELETE = 0x2, NIM_MODIFY = 0x1, NIM_SETVERSION = 0x4 }

    [StructLayout(LayoutKind.Sequential)]
    public struct NOTIFYICONDATA
    {
        public Int32 cbSize;
        public IntPtr hWnd;
        public Int32 uID;
        public NotifyFlags uFlags;
        public Int32 uCallbackMessage;
        public IntPtr hIcon;
        [MarshalAs(UnmanagedType.ByValTStr, SizeConst = 128)]
        public String szTip;
        public Int32 dwState;
        public Int32 dwStateMask;
        [MarshalAs(UnmanagedType.ByValTStr, SizeConst = 256)]
        public String szInfo;
        public Int32 uVersion;
        [MarshalAs(UnmanagedType.ByValTStr, SizeConst = 64)]
        public String szInfoTitle;
        public Int32 dwInfoFlags;
        public Guid guidItem; //> IE 6
        public IntPtr hBalloonIcon;
    }

    [DllImport("shell32.dll")]
    public static extern System.Int32 Shell_NotifyIcon(NotifyCommand cmd, ref NOTIFYICONDATA data);

    private void AddBalloon(string title, string message, Image image)
    {
        NOTIFYICONDATA data = new NOTIFYICONDATA();

        data.cbSize = Marshal.SizeOf(data);
        data.uID = 0x01;
        data.hWnd = Handle;
        data.dwInfoFlags = NIIF_USER;
        data.hIcon = Icon.Handle;
        data.hBalloonIcon = IntPtr.Zero;
        if (message.Image != null)
        {
            data.hBalloonIcon = ((Bitmap)image).GetHicon();
            data.dwInfoFlags |= NIIF_LARGE_ICON;
        }
        data.szInfo = message;
        data.szInfoTitle = title;

        data.uFlags = NotifyFlags.NIF_INFO | NotifyFlags.NIF_SHOWTIP | NotifyFlags.NIF_REALTIME;

        Shell_NotifyIcon(NotifyCommand.NIM_MODIFY, ref data) != 1);
    }

我曾建议：

notificationIcon.Icon =  new Icon(Properties.Resources.ResourceManager.GetStream("<Image Location From root>"));

并将系统托盘图标更改回原始图标，使引出序号提示中的图标保留为新图标。

无帮助：（这将设置任务栏中显示的图标-它不会影响引出序号通知图标。

private void notifyIcon_BalloonTipShown(object sender, EventArgs e)
