Propriedades

  Nome Descrição
Propriedade pública DebugMode A Boolean that indicates whether WmiDataReaderTask should check if breakpoints are enabled.
Propriedade pública Destination Gets or sets the name of the destination for the WmiDataReaderTask.
Propriedade pública DestinationType Gets or sets a DestinationType value that indicates the type of destination, such as a file or a variable, used by the WmiDataReaderTask.
Propriedade pública ExecutionValue Gets an Object that contains the results of the WmiDataReaderTask task. (Substitui Task. . :: . .ExecutionValue.)
Propriedade pública Output Gets or sets an Object that contains the results of the WmiDataReaderTask task.
Propriedade pública OutputType Gets or sets a OutputType value that indicates the type of output, such as a DataTable or a string, returned by the WmiDataReaderTask.
Propriedade pública OverwriteDestination Gets or sets a OverwriteDestination value that determines how the WmiDataReaderTask should handle existing data in the destination specified by the Destination property.
Propriedade pública 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.
Propriedade pública Version *** Member deprecated; see Remarks. ***    Returns the version of the task. This property is read-only. (Herdado de Task.)
Propriedade pública WmiConnection Gets or sets the name of the WMIConn used by the WmiDataReaderTask task.
Propriedade pública WqlQuerySource Gets or sets the source of the Windows Management Instrumentation Query Language (WQL) query to be executed by the WmiDataReaderTask.
Propriedade pública 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.

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

Comentários

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.
