Proprietà

	Nome	Descrizione
	DebugMode	A Boolean that indicates whether WmiDataReaderTask should check if breakpoints are enabled.
	Destination	Gets or sets the name of the destination for the WmiDataReaderTask.
	DestinationType	Gets or sets a DestinationType value that indicates the type of destination, such as a file or a variable, used by the WmiDataReaderTask.
	ExecutionValue	Gets an Object that contains the results of the WmiDataReaderTask task. Esegue l'override di Task.ExecutionValue.
	Output	Gets or sets an Object that contains the results of the WmiDataReaderTask task.
	OutputType	Gets or sets a OutputType value that indicates the type of output, such as a DataTable or a string, returned by the WmiDataReaderTask.
	OverwriteDestination	Gets or sets a OverwriteDestination value that determines how the WmiDataReaderTask should handle existing data in the destination specified by the Destination property.
	SuspendRequired	Gets or sets a Boolean that indicates if tasks should suspend when they encounter a breakpoint. This value is set by the runtime engine for tasks and containers when a breakpoint is encountered.
	Version	*** Member deprecated; see Remarks. ***    Returns the version of the task. This property is read-only. Ereditato da Task.
	WmiConnection	Gets or sets the name of the WMIConn used by the WmiDataReaderTask task.
	WqlQuerySource	Gets or sets the source of the Windows Management Instrumentation Query Language (WQL) query to be executed by the WmiDataReaderTask.
	WqlQuerySourceType	Gets or sets a QuerySourceType value that indicates the source type, such as file connection or a variable, of the Windows Management Instrumentation Query Language (WQL) query to be executed by the WmiDataReaderTask.

Metodi

	Nome	Descrizione
	AcceptBreakpointManager	Passes a BreakpointManager reference to the WmiDataReaderTask task. This method is called by the runtime and is not used in code.
	CanUpdate	*** Member deprecated; see Remarks. ***    A Boolean that indicates whether the new package XML can update the old package XML. Ereditato da Task.
	Equals	Determines whether two object instances are equal. Ereditato da DtsObject.
	Execute	Runs the task. Esegue l'override di Task.Execute(Connections, VariableDispenser, IDTSComponentEvents, IDTSLogging, Object).
	GetConnectionID	Gets a String containing the ID of the connection. Ereditato da Task.
	GetConnectionName	Gets a String containing the name of the connection. Ereditato da Task.
	GetHashCode	Returns the hash code for this instance. Ereditato da DtsObject.
	GetType	Ereditato da Object.
	InitializeTask	Initializes the properties associated with the WmiDataReaderTask task. This method is called by the runtime and is not used in code. Esegue l'override di Task.InitializeTask(Connections, VariableDispenser, IDTSInfoEvents, IDTSLogging, EventInfos, LogEntryInfos, ObjectReferenceTracker).
	LoadFromXML	This method is not callable by your application code. To load a package saved as .xml, use the Application.LoadPackage method.
	ResumeExecution	Resumes execution of the task after pausing. The task or container is resumed by the runtime engine.
	SaveToXML	This method is not callable by your application code. To save a package as .xml, use the Application.SaveToXml method.
	SuspendExecution	Indicates that the executable needs to suspend. This method is called by the runtime engine.
	ToString	Ereditato da Object.
	Update	*** Member deprecated; see Remarks. ***    This method updates the old package XML with the new package XML if CanUpdate is set to true. Ereditato da Task.
	Validate	Verifies that the task is properly configured. Esegue l'override di Task.Validate(Connections, VariableDispenser, IDTSComponentEvents, IDTSLogging).

Osservazioni

The class uses a WMIConn connection to connect to a server, execute a Windows Management Instrumentation Query Language (WQL) query against it, and return the results. The WQL query can either be provided directly, or a variable or file connection can be used to dynamically provide WQL queries at execution time.

Similarly, this class can use either a file connection or variable to receive the results of the WQL query. The output type of the WQL query results can also be specified.
