WMI class ' Win32_MappedLogicalDisk ' reference for C# and VB.NET

MOF Reference

[Description("The Win32_MappedLogicalDisk class represents a network storage devices that are mapped as logical disks on the computer system. The instances returned for this class will be as follows.\nIf user A is enumerating the instances, then the provider will look for a logon session of user A on that machine. If there is one (and only one) such logon session, then the provider will return the mapped drives of that session. If there is more than one session that user A has on the machine, then no mapped drive instances will be returned (since the provider has no reasonable way of deciding which session to use). If there are no sessions of user A running, and there is a locally logged on user B, then the provider will impersonate A and return the mapped drives of user B. This case supports the scenario of helpdesk wanting to see the instances of a locally logged on user. Again, if there is more than one session of user B running on the machine, then the provider has no way of deciding which to use. In this case no mapped drive instances will be returned."): ToSubClass, AMENDMENT, LOCALE(1033)]

{
	[key, Description("The SessionId property indicates the id of the session used by the user connected to the computer system. The user may be connected to the system via a local logon or via a terminal session."): ToSubClass] string SessionID;
	[Description("The Compressed property indicates whether the logical volume exists as a single compressed entity, such as a DoubleSpace volume.  If file based compression is supported (such as on NTFS), this property will be FALSE."): ToSubClass] boolean Compressed;
	[Description("The FileSystem property indicates the file system on the logical disk.\nExample: NTFS"): ToSubClass] string FileSystem;
	[Description("The MaximumComponentLength property contains the maximum length of a filename component supported by the Win32 drive. A filename component is that portion of a filename between backslashes.  The value can be used to indicate that long names are supported by the specified file system. For example, for a FAT file system supporting long names, the function stores the value 255, rather than the previous 8.3 indicator. Long names can also be supported on systems that use the NTFS file system.\nExample: 255"): ToSubClass] uint32 MaximumComponentLength;
	[Description("The SupportsFileBasedCompression property indicates whether the logical disk partition supports file based compression, such as is the case with NTFS. This property is FALSE, when the Compressed property is TRUE.\nValues: TRUE or FALSE. If TRUE, the logical disk supports file based compression."): ToSubClass] boolean SupportsFileBasedCompression;
	[Description("The VolumeName property indicates the volume name of the logical disk.\nConstraints: Maximum 32 characters"): ToSubClass] string VolumeName;
	[Description("The VolumeSerialNumber property indicates the volume serial number of the logical disk.\nConstraints: Maximum 11 characters\nExample: A8C3-D032"): ToSubClass] string VolumeSerialNumber;
	[Description("The SupportsDiskQuotas property indicates whether this volume supports disk Quotas"): ToSubClass] boolean SupportsDiskQuotas;
	[Description("The QuotasDisabled property indicates that Quota management is not enabled on this volume."): ToSubClass] boolean QuotasDisabled;
	[Description("The QuotasIncomplete property indicates that Quota management was used but has been disabled.  Incomplete refers to the information left in the file system  after quota management has been disabled."): ToSubClass] boolean QuotasIncomplete;
	[Description("The QuotasRebuilding property indicates an active state signifying that the file system is in process of compiling information and setting the disk up for quota management."): ToSubClass] boolean QuotasRebuilding;
	[Description("The ProviderName property indicates the network path name to the logical device."): ToSubClass] string ProviderName;

WMI is a huge subject, so therefore it is practically impossible to provide a comprehensive example program that covers anything. However, the book “Network programming in .NET” (Buy at Amazon UK) (Buy at Amazon US) covers a much wider scope of WMI, and explains how to leverage it to access the bounty of information held within this vast, yet simple object model.
