thanks for the explanation, i understand what i did wrong now. however the code that you gave me doesn't seem to work, i get compile errors.

private void button1_Click(object sender, EventArgs e)
        {
            switch (p.ProcessName.ToLower())
            {
                case "firefox": {}
                case "star": {}
                    {
                        p.Kill;
                        break;
                    }
            }
        }

intellisense is telling "p" doesn't exist.
