System.Management Namespace
- Reference
Provides access to a rich set of management information and management events about the system, devices, and applications instrumented to the Windows Management Instrumentation (WMI) infrastructure. Applications and services can query for interesting management information (such as how much free space is left on the disk, what is the current CPU utilization, which database a certain application is connected to, and much more), using classes derived from ManagementObjectSearcher and ManagementQuery, or subscribe to a variety of management events using the ManagementEventWatcher class. The accessible data can be from both managed and unmanaged components in the distributed environment.
Classes
| CompletedEventArgs | Holds event data for the Completed event. |
|---|---|
| ConnectionOptions | Specifies all settings required to make a WMI connection. |
| DeleteOptions | Specifies options for deleting a management object. |
| EnumerationOptions | Provides a base class for query and enumeration-related options objects. |
| EventArrivedEventArgs | Holds event data for the EventArrived event. |
| EventQuery | Represents a WMI event query. |
| EventWatcherOptions | Specifies options for management event watching. |
| InvokeMethodOptions | Specifies options for invoking a management method. |
| ManagementBaseObject | Contains the basic elements of a management object. It serves as a base class to more specific management object classes. |
| ManagementClass | Represents a Common Information Model (CIM) management class. A management class is a WMI class such as Win32_LogicalDisk, which can represent a disk drive, and Win32_Process, which represents a process such as Notepad.exe. The members of this class enable you to access WMI data using a specific WMI class path. |
| ManagementDateTimeConverter | Provides methods to convert Desktop Management Task Force (DMTF) date-time and time intervals to CLR-compliant DateTime and TimeSpan format and vice versa. |
| ManagementEventArgs | Represents the virtual base class to hold event data for WMI events. |
| ManagementEventWatcher | Subscribes to temporary event notifications based on a specified event query. |
| ManagementException | Represents management exceptions. |
| ManagementNamedValueCollection | Represents a collection of named values suitable for use as context information to WMI operations. The names are case-insensitive. |
| ManagementObject | Represents a WMI instance. |
| ManagementObjectCollection | Represents different collections of management objects retrieved through WMI. The objects in this collection are of ManagementBaseObject-derived types, including ManagementObject and ManagementClass. The collection can be the result of a WMI query executed through a ManagementObjectSearcher, or an enumeration of management objects of a specified type retrieved through a ManagementClass representing that type. In addition, this can be a collection of management objects related in a specified way to a specific management object - in this case the collection would be retrieved through a method such as GetRelated(). The collection can be walked using the ManagementObjectCollection.ManagementObjectEnumerator and objects in it can be inspected or manipulated for various management tasks. |
| ManagementObjectCollection.ManagementObjectEnumerator | Represents the enumerator on the collection. |
| ManagementObjectSearcher | Retrieves a collection of management objects based on a specified query. This class is one of the more commonly used entry points to retrieving management information. For example, it can be used to enumerate all disk drives, network adapters, processes and many more management objects on a system, or to query for all network connections that are up, services that are paused, and so on. When instantiated, an instance of this class takes as input a WMI query represented in an ObjectQuery or its derivatives, and optionally a ManagementScope representing the WMI namespace to execute the query in. It can also take additional advanced options in an EnumerationOptions. When the Get() method on this object is invoked, the ManagementObjectSearcher executes the given query in the specified scope and returns a collection of management objects that match the query in a ManagementObjectCollection. |
| ManagementOperationObserver | Manages asynchronous operations and handles management information and events received asynchronously. |
| ManagementOptions | Provides an abstract base class for all options objects. |
| ManagementPath | Provides a wrapper for parsing and building paths to WMI objects. |
| ManagementQuery | Provides an abstract base class for all management query objects. |
| ManagementScope | Represents a scope (namespace) for management operations. |
| MethodData | Contains information about a WMI method. |
| MethodDataCollection | Represents the set of methods available in the collection. |
| MethodDataCollection.MethodDataEnumerator | Represents the enumerator for MethodData objects in the MethodDataCollection. |
| ObjectGetOptions | Specifies options for getting a management object. |
| ObjectPutEventArgs | Holds event data for the ObjectPut event. |
| ObjectQuery | Represents a management query that returns instances or classes. |
| ObjectReadyEventArgs | Holds event data for the ObjectReady event. |
| ProgressEventArgs | Holds event data for the Progress event. |
| PropertyData | Represents information about a WMI property. |
| PropertyDataCollection | Represents the set of properties of a WMI object. |
| PropertyDataCollection.PropertyDataEnumerator | Represents the enumerator for PropertyData objects in the PropertyDataCollection. |
| PutOptions | Specifies options for committing management object changes. |
| QualifierData | Contains information about a WMI qualifier. |
| QualifierDataCollection | Represents a collection of QualifierData objects. |
| QualifierDataCollection.QualifierDataEnumerator | Represents the enumerator for QualifierData objects in the QualifierDataCollection. |
| RelatedObjectQuery | Represents a WQL ASSOCIATORS OF data query. It can be used for both instances and schema queries. |
| RelationshipQuery | Represents a WQL REFERENCES OF data query. |
| SelectQuery | Represents a WQL SELECT data query. |
| StoppedEventArgs | Holds event data for the Stopped event. |
| WqlEventQuery | Represents a WMI event query in WQL format. |
| WqlObjectQuery | Represents a WMI data query in WQL format. |
Enums
| AuthenticationLevel | Describes the authentication level to be used to connect to WMI. This is used for the COM connection to WMI. |
|---|---|
| CimType | Describes the possible CIM types for properties, qualifiers, or method parameters. |
| CodeLanguage | Defines the languages supported by the code generator. |
| ComparisonSettings | Describes the object comparison modes that can be used with CompareTo(ManagementBaseObject, ComparisonSettings). Note that these values may be combined. |
| ImpersonationLevel | Describes the impersonation level to be used to connect to WMI. |
| ManagementStatus | Describes the enumeration of all WMI error codes that are currently defined. |
| PutType | Describes the possible effects of saving an object to WMI when using Put(). |
| TextFormat | Describes the possible text formats that can be used with GetText(TextFormat). |
Delegates
| CompletedEventHandler | Represents the method that will handle the Completed event. |
|---|---|
| EventArrivedEventHandler | Represents the method that will handle the EventArrived event. |
| ObjectPutEventHandler | Represents the method that will handle the ObjectPut event. |
| ObjectReadyEventHandler | Represents the method that will handle the ObjectReady event. |
