这是采集出来的Json，部分电脑（特别是笔记本）无法获取到：

下面是代码：

引用OpenHardwareMonitorLib.dll
调用

	HardwareMonitor hardwareMonitor = new HardwareMonitor();HardwareMonitorModel hardwareMonitorModel = hardwareMonitor.GetHardwareInfo();

实现

public class HardwareMonitor
{private Computer computer;public HardwareMonitor(){computer = new Computer{CPUEnabled = true,GPUEnabled = true,HDDEnabled = true,MainboardEnabled = true,RAMEnabled = true // 新增内存监控};}public HardwareMonitorModel GetHardwareInfo(){var model = new HardwareMonitorModel();try{computer.Open();// 多次更新以确保数据稳定for (int i = 0; i < 3; i++){UpdateAllHardware();System.Threading.Thread.Sleep(100);}// 收集硬件信息foreach (var hardware in computer.Hardware){var hardwareInfo = new HardwareInfo{Name = hardware.Name,Type = GetHardwareTypeString(hardware.HardwareType),WmiReport = hardware.HardwareType == HardwareType.HDD ?
