minimize app to system tray - no icon appears

Question

i need to minimize app to system tray (see my icon there). But after starting the app, the icon dissapears from taskbar (that is fine) but i cannot see it in system tray (that is bad).

Where can be a mistake, please? PS: i am using WPF.

This is inner code of my event:

System.Windows.Forms.NotifyIcon notifyIcon = new System.Windows.Forms.NotifyIcon();
            if (WindowState.Minimized == this.WindowState)
            {
                notifyIcon.Visible = true;
                notifyIcon.BalloonTipText = "Radek app";
                notifyIcon.BalloonTipTitle = "Welcome Message";
                notifyIcon.BalloonTipIcon = System.Windows.Forms.ToolTipIcon.Info;                
                notifyIcon.ShowBalloonTip(3000);                
                this.ShowInTaskbar = false;
            }

            else if (WindowState.Normal == this.WindowState)
            {
                this.WindowState = WindowState.Normal;
                this.ShowInTaskbar = true;
                notifyIcon.Visible = false;
            }

Answer 1

That Info icon is for the balloon, not the TrayIcon itself, you should add your image (I recommend 16x16px png file) to your application resources, then you can use it like:

var iconHandle = Properties.Resources.YourIconImage.GetHicon();
NotifyIcon.Icon = System.Drawing.Icon.FromHandle(iconHandle);

Answer 2

您需要设置图标，如下所示：

notifyIcon.Icon = new System.Drawing.Icon(Path to your Icon);
