C# - 如何使用 LibreHardwareMonitor 獲取 CPU 溫度/CPU 負載/當前電壓/VID 電壓/當前頻率？

Question

對於我的 C#.Net Framework 項目，我需要獲得 5 個值：

1. CPU負載
2. 處理器溫度
3. 當前電壓
4. 顯示電壓
5. 當前頻率

我試過 WMI，但它不適用於現代 CPU，並且無法正確獲取這些值。 在做了一些研究之后，我認為獲取這些值的最佳方法是使用 OpenHardwareMonitor 或 LibreHardwareMonitor ( Git )。

因此，我安裝了 LibreHardwareMonitor NuGet，它添加了所有引用和 GitHub 編譯的示例代碼，但控制台立即關閉。

從下面的示例代碼中，您可以看出它輸出了它可以獲得的每個指標，而我只需要上面提到的那 5 個值。

如果有人有使用 LibreHardwareMonitor 或 OpenHardwareMonitor 的經驗，如果你能告訴我如何獲得我需要的那些值，我將不勝感激。

public class UpdateVisitor : IVisitor
{
    public void VisitComputer(IComputer computer)
    {
        computer.Traverse(this);
    }
    public void VisitHardware(IHardware hardware)
    {
        hardware.Update();
        foreach (IHardware subHardware in hardware.SubHardware) subHardware.Accept(this);
    }
    public void VisitSensor(ISensor sensor) { }
    public void VisitParameter(IParameter parameter) { }
}

public void Monitor()
{
    Computer computer = new Computer
    {
        IsCpuEnabled = true,
        IsGpuEnabled = true,
        IsMemoryEnabled = true,
        IsMotherboardEnabled = true,
        IsControllerEnabled = true,
        IsNetworkEnabled = true,
        IsStorageEnabled = true
    };

    computer.Open();
    computer.Accept(new UpdateVisitor());

    foreach (IHardware hardware in computer.Hardware)
    {
        Console.WriteLine("Hardware: {0}", hardware.Name);
        
        foreach (IHardware subhardware in hardware.SubHardware)
        {
            Console.WriteLine("\tSubhardware: {0}", subhardware.Name);
            
            foreach (ISensor sensor in subhardware.Sensors)
            {
                Console.WriteLine("\t\tSensor: {0}, value: {1}", sensor.Name, sensor.Value);
            }
        }

        foreach (ISensor sensor in hardware.Sensors)
        {
            Console.WriteLine("\tSensor: {0}, value: {1}", sensor.Name, sensor.Value);
        }
    }
    
    computer.Close();
}

只需將此代碼與 OpenHardwareMonitor 一起使用。 然后從ReportSystemInfo()中提取cpuUsage、cpuTemp等；

using System;
using OpenHardwareMonitor.Hardware;

namespace PPSU_hwmonitor_c
{
    class Program
    {
        /**
         *  Define vars to hold stats
         **/

        // CPU Temp
        static float cpuTemp;
        // CPU Usage
        static float cpuUsage;
        // CPU Power Draw (Package)
        static float cpuPowerDrawPackage;
        // CPU Frequency
        static float cpuFrequency;
        // GPU Temperature
        static float gpuTemp;
        // GPU Usage
        static float gpuUsage;
        // GPU Core Frequency
        static float gpuCoreFrequency;
        // GPU Memory Frequency
        static float gpuMemoryFrequency;

        /**
         * Init OpenHardwareMonitor.dll Computer Object
         **/

        static Computer c = new Computer()
        {
            GPUEnabled = true,
            CPUEnabled = true,
            //RAMEnabled = true, // uncomment for RAM reports
            //MainboardEnabled = true, // uncomment for Motherboard reports
            //FanControllerEnabled = true, // uncomment for FAN Reports
            //HDDEnabled = true, // uncomment for HDD Report
        };

        /**
         * Pulls data from OHM
         **/

        static void ReportSystemInfo()
        {
            foreach (var hardware in c.Hardware)
            {

                if (hardware.HardwareType == HardwareType.CPU)
                {
                    // only fire the update when found
                    hardware.Update();

                    // loop through the data
                    foreach (var sensor in hardware.Sensors)

                        }

Answer 2

我試過你的答案，但對於溫度和 cpu 時鍾（可能還有其他），結果是 0。這是我的輸出：

CPU使用率：5,867474
CPU溫度：0
CPU頻率：0
顯卡溫度：28
GPU核心頻率：1139
gpu內存頻率：4303,992
GPU使用率：1

我錯過了什么？
