C#设置开机启动项代码

/要触发的事件，一般是checkBox1的CheckedChanged事件
private void checkBox1_CheckedChanged(object sender, EventArgs e)
        {
            if (checkBox1.Checked) //设置开机自启动  
            {
                MessageBox.Show ("设置开机自启动，需要修改注册表","提示");  // hovertree.com
                string path = Application.ExecutablePath;
                RegistryKey rk = Registry.LocalMachine;
                RegistryKey rk2 = rk.CreateSubKey(@"Software\Microsoft\Windows\CurrentVersion\Run");
                rk2.SetValue("JcShutdown", path);
                rk2.Close();
                rk.Close();
            }
            else //取消开机自启动  
            {
                MessageBox.Show ("取消开机自启动，需要修改注册表","提示");  
                string path = Application.ExecutablePath;
                RegistryKey rk = Registry.LocalMachine;
                RegistryKey rk2 = rk.CreateSubKey(@"Software\Microsoft\Windows\CurrentVersion\Run");
                rk2.DeleteValue("JcShutdown", false);
                rk2.Close();
                rk.Close();
            }  
        }
