private static PerformanceCounter cpuCounter;
private static PerformanceCounter memoryCounter;

cpuCounter = new PerformanceCounter
{
   CategoryName = "Processor",
   CounterName = "% Processor Time",
   InstanceName = "_Total"
};

memoryCounter = new PerformanceCounter
{
    CategoryName = "Memory",
    CounterName = "Available Bytes"
};
[...]
public double CpuUsage
{
   get
   {
      lock (lockToken)
      {
          return Math.Round(cpuCounter.NextValue(), 2);
      }
   }
 }
 public double MemoryUsage
 {
    get
    {
       lock (lockToken)
       {
          return Math.Round(memoryCounter.NextValue() / totalMemory * 100, 2);
       }
    }
  }

总内存：

 using (var searcher = new ManagementObjectSearcher("SELECT totalphysicalmemory FROM Win32_ComputerSystem"))
        {
            using (var wmiData = searcher.Get())
            {
                foreach (var mo in wmiData)
                {
                    totalMemory = long.Parse(mo["totalphysicalmemory"].ToString());
                }
            }
        }

为了获得虚拟内存，你必须自己做一些研究。
