c# - 如何读取硬盘温度？

Question

是否可以使用某种 SMART API 或类似的东西查看硬盘温度？

我只想要温度，C# 中没有别的

Answer 1

这是本文的代码片段 希望对您有所帮助

//S.M.A.R.T.  Temperature attribute
const byte TEMPERATURE_ATTRIBUTE = 194;

public List<byte> GetDriveTemp()
{
    var retval = new List<byte>();
    try
    {
        ManagementObjectSearcher searcher = new ManagementObjectSearcher("root\\WMI", "SELECT * FROM MSStorageDriver_ATAPISmartData");
        //loop through all the hard disks
        foreach (ManagementObject queryObj in searcher.Get())
        {
            byte[] arrVendorSpecific = (byte[])queryObj.GetPropertyValue("VendorSpecific");
            //Find the temperature attribute
            int tempIndex = Array.IndexOf(arrVendorSpecific, TEMPERATURE_ATTRIBUTE);
            retval.Add(arrVendorSpecific[tempIndex + 5]);
        }
    }
    catch (ManagementException err)
    {
        Console.WriteLine("An error occurred while querying for WMI data: " + err.Message);
    }
    return retval;
}

使用 VMI 并MSStorageDriver_ATAPISmartData获取VendorSpecific字节数组和 115 字节数是温度。为什么是115？更多在这里。

使用VMI Code Creator生成的部分代码

ManagementObjectSearcher searcher = new ManagementObjectSearcher("root\\WMI",
"SELECT * FROM MSStorageDriver_ATAPISmartData");

foreach (ManagementObject queryObj in searcher.Get())
{
   if (queryObj["VendorSpecific"] != null)
   {
       byte[] arrVendorSpecific = (byte[])(queryObj["VendorSpecific"]);
       string temp = arrVendorSpecific[115].ToString();
    }
 }
