c# - 在Win32_Volume中设置属性

Question

我试图弄清楚如何为磁盘设置“IndexingEnabled”属性值(启用/禁用磁盘索引)。从文档中可以得出，可以读取/写入此属性。

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
    }
}

或者

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);
    }
}

不会生成错误，但是属性的值不会更改。管理员权限处于 Activity 状态。我究竟做错了什么？谢

SetPropertyValue仅更新包装对象。直到 Put 被调用(例如volume.Put();)，更改才会提交(并且不会生效)。
