C＃列出所有分区，包括Microsoft保留分区

Question

ManagementClass devs = new ManagementClass(@"Win32_Diskdrive");
ManagementObjectCollection moc = devs.GetInstances();
foreach (ManagementObject mo in moc)
{
    UInt32 physicalDiskNumber = (UInt32)mo["Index"];
    UInt64 diskSize = (UInt64)mo["Size"];
    foreach (ManagementObject b in mo.GetRelated("Win32_DiskPartition"))
    {
        //b["Name"] gives something like "Disk #0, Partition #0"
        string[] elems = b["Name"].ToString().Split(',');
        int partitionNumber = Int32.Parse(elems[1].Replace("Partition #", "").Trim());
        ulong size = (ulong) b["Size"];

    }
}

这是我的代码，用于检索所有磁盘上的所有分区。但是，它不会检索Microsoft保留分区。我想检索磁盘上的所有分区，包括MSR分区。我怎样才能在C＃中实现这个目标？
