C#获取计算机的计数器个数和物理内存

            //CPU个数 
            m_ProcessorCount = Environment.ProcessorCount;

            //获得物理内存 
            ManagementClass mc = new ManagementClass("Win32_ComputerSystem");
            ManagementObjectCollection moc = mc.GetInstances();
            foreach (ManagementObject mo in moc)
            {
                if (mo["TotalPhysicalMemory"] != null)
                {
                    m_PhysicalMemory = long.Parse(mo["TotalPhysicalMemory"].ToString());
                }
            }
