阻止控制台程序退出

阻止控制台程序退出的一个方法，取自 surging的服务端。

class Program
    {
        //用来阻止程序退出
        private static readonly ManualResetEvent _shutdownBlock = new ManualResetEvent(false);
        static void Main(string[] args)
        {
            Console.WriteLine("Hello World!");
　　　　　　　//启动其他线程
            //Console.Read();
            Console.CancelKeyPress += Console_CancelKeyPress;
            AppDomain.CurrentDomain.ProcessExit += (sender, eventArgs) =>
            {
　　　　　　　　　　//等待退出信号触发
                _shutdownBlock.WaitOne();
            };
        }
        //Ctrl+C 退出程序
        private static void Console_CancelKeyPress(object sender, ConsoleCancelEventArgs e)
        {
            e.Cancel = true;
            _shutdownBlock.Set();
        }
    }

 另：asp.net Core也是采用此方法
