WMI获取磁盘的GUID路径- wangbin5542 - 博客园企业库|免费b2b网站

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());
            }

Windows Management Instrumentation (WMI)

class Win32_Volume : CIM_StorageVolume
{
uint16 Access;
uint16 Availability;
uint64 BlockSize;
string Caption;
uint32 ConfigManagerErrorCode;
boolean ConfigManagerUserConfig;
string CreationClassName;
string Description;
boolean ErrorCleared;
string ErrorDescription;
string ErrorMethodology;
datetime InstallDate;
uint32 LastErrorCode;
string Name;
uint64 NumberOfBlocks;
string PNPDeviceID;
uint16[] PowerManagementCapabilities;
boolean PowerManagementSupported;
string Purpose;
string Status;
uint16 StatusInfo;
string SystemCreationClassName;
string SystemName;
string DeviceID;
uint64 Capacity;
boolean Compressed;
string DriveLetter;
uint32 DriveType;
string FileSystem;
uint64 FreeSpace;
boolean IndexingEnabled;
boolean DirtyBitSet;
string Label;
uint32 MaximumFileNameLength;
boolean Automount;
boolean QuotasEnabled;
boolean QuotasIncomplete;
boolean QuotasRebuilding;
