C#擷取CPU溫度（OpenHardwareMonitorLib.dll庫）

作者嘗試過WinIo，Rdmsr，WMI，OpenHardwareMonitorLib。OpenHardwareMonitorLib和rdmsr都是用的WinRing0.sys驅動，然後要在程式裡面加載這個驅動就可讀取這些寄存器的值。OpenHardwareMonitorLib把驅動封裝到自己的内部來了，這裡講的是OpenHardwareMonitorLib的方法，很簡單：

OpenHardwareMonitorLib.dll下載下傳位址：​​javascript:void(0)​​

1、下載下傳OpenHardwareMonitorLib庫，并引用到項目中
