            Console.WriteLine(pc.CounterName);
            Console.WriteLine(pc.CounterHelp);
            while(true)
            {
                Thread.Sleep(TimeSpan.FromSeconds(1));
                float cpuInfo = pc.NextValue();
                Console.WriteLine("cpu当前使用率为{0}",cpuInfo);
            }
