无需 WMI 即可获取电池信息

发布于 2024-11-02 09:47:20 字数 491 浏览 0 评论 0原文

有没有办法在没有 WMI 的情况下获取电池 DesignCapacity 和 FullChargeCpacity ？ WMI 不支持此值，因此我需要找到其他方法来获取它们。

或者也许有人有更好（更简单）的想法来获取 C# 中电池的磨损程度？

顺便提一句我尝试以这种方式使用它，但只是返回 null

ManagementObjectSearcher query = 
        new ManagementObjectSearcher("SELECT DesignCapacity FROM Win32_Battery");

foreach (ManagementObject queryObj in query.Get())
{
    string dc = Convert.ToString(queryObj.GetPropertyValue("DesignCapacity"));
    label1.Text = dc + " mAh";
}

谢谢

Is there some way to obtain the battery DesignCapacity and FullChargeCpacity without WMI ?
This values are not supported in WMI so I need to find other way to get them.

Or maybe somebody have better (easier) idea to get the wear level of battery in C#?

BTW
I try to use it this way but just returned null

ManagementObjectSearcher query = 
        new ManagementObjectSearcher("SELECT DesignCapacity FROM Win32_Battery");

foreach (ManagementObject queryObj in query.Get())
{
    string dc = Convert.ToString(queryObj.GetPropertyValue("DesignCapacity"));
    label1.Text = dc + " mAh";
}

Thanks

要获取这些特定值，您需要针对不同的类而不是 win32_battery 进行单独的查询。

DesignCapacity 可以从 BatteryStaticData 查询

FullChargeCacity 可以从 BatteryFullChargedCapacity 查询

您还需要在代码中使用不同的范围来进行查询。这些类位于 root/WMI 中，而不是 root/cimv2

string scope = "root/WMI";
string query = "SELECT DesignedCapacity FROM BatteryStaticData";

ManagementObjectSearcher batteriesQuery = new ManagementObjectSearcher(scope, query);

ManagementObjectCollection batteries = batteriesQuery.Get();

foreach (ManagementObject battery in batteries)
{
    if (battery != null)
    {
        foreach (var property in battery.Properties)
        {
            Console.Log("Property name: " + property.Name + " Property value: " + property.Value);
        }
    }
}

To get those particular values you need to do separate queries against different classes instead of win32_battery.

DesignCapacity can be queried from BatteryStaticData

FullChargeCacity can be queried from BatteryFullChargedCapacity

You'll need to use a different scope in the code also for the query. These classes are found in root/WMI instead of root/cimv2

string scope = "root/WMI";
string query = "SELECT DesignedCapacity FROM BatteryStaticData";

ManagementObjectSearcher batteriesQuery = new ManagementObjectSearcher(scope, query);

ManagementObjectCollection batteries = batteriesQuery.Get();

foreach (ManagementObject battery in batteries)
{
    if (battery != null)
    {
        foreach (var property in battery.Properties)
        {
            Console.Log("Property name: " + property.Name + " Property value: " + property.Value);
        }
    }
}
