Hardware.Info本地开发运行没问题，放到服务器上抛异常

var hardwareInfo = new HardwareInfo();
hardwareInfo.RefreshAll(); // 刷新所有设备信息
MachineInfo info = new MachineInfo()
{
   // CPU信息
   CpuList = hardwareInfo.CpuList.Select(s => new MachineInfo.CPUInfo()
   {
	   Name = s.Name,
	   NumberOfCores = s.NumberOfCores,
	   NumberOfLogicalProcessors = s.NumberOfLogicalProcessors
   }).ToList(),

   // 内存信息
   Memory = new MachineInfo.MemoryInfo()
   {
	   TotalPhysical = hardwareInfo.MemoryStatus.TotalPhysical,
	   MemoryList = hardwareInfo.MemoryList.Select(s => new MachineInfo.MemoryItem()
	   {
		   Capacity = s.Capacity,
		   FormFactor = s.FormFactor.ToString(),
		   Manufacturer = s.Manufacturer,
		   PartNumber = s.PartNumber,
		   SerialNumber = s.SerialNumber,
		   Speed = s.Speed
	   }).ToList()
   },

   // 主板信息
   MotherboardList = hardwareInfo.MotherboardList.Select(s => new MachineInfo.MotherboardInfo()

   }).ToList(),

   // 系统信息
   OperatingSystem = new MachineInfo.OSInfo()
   {

   }
};

var hardwareInfo = new HardwareInfo();
//hardwareInfo.RefreshAll(); // 必须要这一行代码，不然不会更新,服务器没有显示器，会抛异常
hardwareInfo.RefreshCPUList(); // CPU 
hardwareInfo.RefreshMemoryStatus(); // 内存状态
hardwareInfo.RefreshMemoryList(); // 内存列表
hardwareInfo.RefreshMotherboardList(); // 主板
hardwareInfo.RefreshNetworkAdapterList(); // 网卡
hardwareInfo.RefreshOperatingSystem(); // 系统
hardwareInfo.RefreshDriveList(); // 硬盘
