WMI获取磁盘的GUID路径

Windows支持一种特殊的UNC (Universal Naming Convention)路径表示法：\\?\Volume{}。例如我的D盘可以表示成\\?\Volume{7676e0e1-60fd-11de-a55b-806e6f6e6963}\。

获取到磁盘的GUID路径

Caption:盘符

DeviceID:GUID路径

例如：

   SelectQuery selectQuery = new
               SelectQuery("Win32_Volume");
            ManagementObjectSearcher searcher =
                new ManagementObjectSearcher(selectQuery);
            foreach (ManagementObject disk in searcher.Get())
            {
                tmpArray.Add(disk.Properties["Caption"].Value.ToString());
                tmpArray2.Add(disk.Properties["DeviceID"].Value.ToString());
            }

class Win32_Volume : CIM_StorageVolume

uint16 Access;

string SystemCreationClassName;
string SystemName;
string DeviceID;
uint64 Capacity;
boolean Compressed;
string DriveLetter;
