WPF的Application.Current.Shutdown()与Environment.Exit(0)区别

            Task.Factory.StartNew(() =>
            {
                Thread.CurrentThread.IsBackground = false;
                for (int i = 0; i < 1000; i++)
                {
                    Thread.Sleep(1000);
                    string s = i + " ";
                }
            });
            //①，Application.Current.Shutdown();
            //②，Environment.Exit(0);

1、当 Thread.CurrentThread.IsBackground = false; 时 ①只关掉了UI而后台进程没有关掉；

2、当 Thread.CurrentThread.IsBackground = true; 时 ①②都可以关掉UI和进程。

3、Process.GetCurrentProcess().Kill(); 彻底结束进程
