Question

我需要使用WMI获取机器的电源设置。我正在使用MSDN Link来获取所需的值。我需要返回列表中的特定值。以下C＃代码执行此操作：

string NamespacePath = @"root\cimv2\power";
string powerPlanClass = "Win32_powerplan";
string powerSettingClass = "Win32_PowerSettingDataIndex";

ManagementClass powerPlanManagementClass = new ManagementClass(NamespacePath + ":" + powerPlanClass);
ManagementObject powerPlanManagementObject = null;
foreach (ManagementObject managementObject in powerPlanManagementClass.GetInstances())
{
    if (managementObject["IsActive"] != null && Boolean.Parse(managementObject["IsActive"].ToString()))
    {
        powerPlanManagementObject = managementObject;
    }
}

Dictionary<string, PowerSetting> powerItems = new Dictionary<string, PowerSetting>()
    {
       {"AC", new PowerSetting() },
       {"DC", new PowerSetting() }
    };


foreach (ManagementObject oObject in powerPlanManagementObject.GetRelated(powerSettingClass))
        {
            var instanceId = oObject["instanceId"];
            string[] powerSourceSettings = instanceId.ToString().Split(new string[] { @"\" }, StringSplitOptions.RemoveEmptyEntries);
            var powerSourceType = powerSourceSettings[2];
            ManagementObjectCollection managementObjects = oObject.GetRelated("Win32_PowerSetting");
            var elementName = string.Empty;
            foreach (var managementObject in managementObjects)
            {
                elementName = managementObject["ElementName"].ToString();
            }
            var indexValue = uint.Parse(oObject["settingindexvalue"].ToString());

            if (elementName.Equals("Hibernate after",StringComparison.OrdinalIgnoreCase))
            {                    
                if (powerSourceType.Equals("AC", StringComparison.Ordinal))
                {
                    powerItems["AC"].HibernateAfter = indexValue;
                }                    
            }
        }

请注意匹配字符串“Hibernate after”。这适用于具有语言环境的计算机，但不适用于其他语言环境。有没有其他方法可以使WMI属性独立于机器的语言环境？

您可以在Win32_PowerSetting课程的InstanceID而不是ElementName中使用GUID。在我的机器中，它是Microsoft:PowerSetting\{9d7815a6-7ee4-497e-8888-515a05f02364}。虽然我找不到官方文档，但是这个GUID 9d7815a6-7ee4-497e-8888-515a05f02364似乎对于某些Windows版本和语言环境来说是常见的，因为＆＃34; hibernate之后的标识符是＆＃34;或者＆＃34; hibernate idle＆＃34;。
