C# 在Win32\u卷中设置属性

我试图弄清楚如何为磁盘设置“IndexingEnabled”属性值（磁盘索引已启用/禁用）。从文档中可以看出，此属性可以读/写

using (ManagementObjectSearcher Win32_Volume =
    new ManagementObjectSearcher("Select IndexingEnabled from Win32_Volume where DriveLetter = 'C:'"))
{
    foreach (ManagementObject volume in Win32_Volume.Get())
    {
        volume.SetPropertyValue("IndexingEnabled", true); // true or false
    }
}

或

不会生成错误，但属性的值不会更改。管理员权限处于活动状态。我做错了什么？thank

SetPropertyValue

仅更新包装器对象。在调用之前不会提交更改（并且不会生效），例如

volume.Put（）

ManagementScope scope = new ManagementScope("\\\\.\\root\\cimv2");
ObjectQuery query = new ObjectQuery("Select IndexingEnabled from Win32_Volume where DriveLetter='C:'");
scope.Connect();

using (ManagementObjectSearcher searcher = new ManagementObjectSearcher(scope, query))
{
    foreach (ManagementBaseObject drive in searcher.Get())
    {
        drive.SetPropertyValue("IndexingEnabled", true);
    }
}
