Minimizing to system tray

I'm trying and failing at minimizing my program to my system tray. Can someone tell me what I'm doing wrong?

private void button3_Click(object sender, EventArgs e)

{

System.Windows.Forms.NotifyIcon ni = new System.Windows.Forms.NotifyIcon();

ni.Icon = new System.Drawing.Icon("icon.ico");

ni.Visible = true;

ni.DoubleClick += delegate(object sender, EventArgs args)

{

this.Show();

this.WindowState = FormWindowState.Normal;

};

this.ShowInTaskbar = false;

}

Your method has a parameter named sender, and when you use sender name as a parameter at your delegate they confilict.

So change the name of the parameter at your anonymous delegate at NotifyIcon Doubleclick method tosomething else.

ni.DoubleClick +=

delegate(object sender1, EventArgs args)

You are forgetting to call this.Hide().

Error 1 A local variable named 'sender' cannot be declared in this scope because it would give a different meaning to 'sender', which is already used in a 'parent or current' scope to denote something else ni.DoubleClick += delegate(object sender, EventArgs args)

that line errors, is my issue.

ni.DoubleClick +=
