c#获取电脑运行状态（cpu,内存，网络，系统运行时间）

 public class DeviceMonitor
    {

        static readonly PerformanceCounter cpuCounter = new PerformanceCounter("Processor", "% Processor Time", "_Total");
        static readonly PerformanceCounter ramCounter = new PerformanceCounter("Memory", "Available MBytes");
        static readonly PerformanceCounter uptime = new PerformanceCounter("System", "System Up Time");


        public static bool GetInternetAvilable()
        {
            bool networkUp = System.Net.NetworkInformation.NetworkInterface.GetIsNetworkAvailable();
            return networkUp;
        }

        public static TimeSpan GetSystemUpTime()
        {
            uptime.NextValue();
            TimeSpan ts = TimeSpan.FromSeconds(uptime.NextValue());
            return ts;
        }

        public static string GetPhysicalMemory()
        {
            string str = null;
            ManagementObjectSearcher objCS = new ManagementObjectSearcher("SELECT * FROM Win32_ComputerSystem");
            foreach (ManagementObject objMgmt in objCS.Get())
            {
                str = objMgmt["totalphysicalmemory"].ToString();
            }
            return str;
        }

        public static string getCurrentCpuUsage()
        {
            return cpuCounter.NextValue() + "%";
        }

        public static string getAvailableRAM()
        {
            return ramCounter.NextValue() + "MB";
        }
    }

　

显示：

 Console.WriteLine("网络是否可用：" + DeviceMonitor.GetInternetAvilable());
                Console.WriteLine("系统已运行时间：" + DeviceMonitor.GetSystemUpTime());
                Console.WriteLine("物理总内存：" +  (double.Parse(DeviceMonitor.GetPhysicalMemory())/(1024*1024*1024)).ToString("F2")+"GB" );
                Console.WriteLine("当前CPU值：" + DeviceMonitor.getCurrentCpuUsage());
                Console.WriteLine("当前可用内存：" + DeviceMonitor.getAvailableRAM());

　效果：
