C# 写的一个 Windows 服务，无法安装，一直报错！

    public partial class MyService : ServiceBase
    {
        int i = 0;
        bool iswhile = true;
        public MyService()
        {
            InitializeComponent();
        }

        protected override void OnStart(string[] args)
        {
            Task.Factory.StartNew(() =>
            {
                while (iswhile)
                {
                    LogHelper.Write("Run " + i);
                    Thread.Sleep(1000);
                }
            });
        }

        protected override void OnStop()

            iswhile = false;
            Thread.Sleep(1000);
            LogHelper.Write("End Run " + i);
        }
