C#设置程序开机自启动，代码别人的，没有经过测试

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");                  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();            }          }
