C#用opneHardwareMonitor获取显卡温度

Question

C#用OpenHardwareMonitor读显卡温度为什么都说可以用，但是一只是卡在computer.Open();这一直找不到系统文件，有什么办法能解决嘛，源码网上找的

Answer 1

你的代码没大毛病，测试了nuget上2个版本的dll，都是可以的；显然2021年的OpenHardwareMonitor.0.9.6更科学；
另外你的那个判断Name多余。
版本1：OpenHardwareMonitorLibCore.1.0.2

版本2、nuget的 OpenHardwareMonitor.0.9.6

这是测试代码，添加nuget引用就能跑了。

        public static void Main(string[] args)

            var computer = new Computer();
            computer.Open();
            computer.CPUEnabled = true; //这个很关键
            computer.Accept(updateVisitor);

            for (int i = 0; i < computer.Hardware.Length; i++)
            {
