Consistently Declare objects in Webservices

1句話

不要忘記 webservice 也是一個 class

是 class 就有 constructor

以上。

        protected PerformanceCounter cpuUsage;// = new PerformanceCounter("Processor","% Processor Time","_Total");
        protected PerformanceCounter ramUsage;// = new PerformanceCounter("Memory","Available MBytes");
        //protected CounterSample sample;
        
        public monitor()
        {
            cpuUsage = new PerformanceCounter("Processor","_Total");
            ramUsage = new PerformanceCounter("Memory","Available MBytes");
            //sample = cpuUsage.NextSample();
        }

        
        [WebMethod]
        public float getHostCpuUsage()
        {
            cpuUsage.NextValue();
            Thread.Sleep(100);
            cpuUsage.NextValue();
            Thread.Sleep(100);
            return cpuUsage.NextValue();
        }

        [WebMethod]
        public float getHostMemUsage()
        {
            return ramUsage.NextValue();
        }
