Конструкторы

  Имя Описание
Открытый метод WmiDataReaderTask Initializes a new instance of the WmiDataReaderTask class.

В начало

Свойства

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

Методы

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

Замечания

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.

For more information about the features of this task, see Задача «Модуль чтения данных WMI».

Безопасность многопоточности

Любые открытые статический (Shared в Visual Basic) элементы этого типа потокобезопасны. Потокобезопасность с элементами экземпляров не гарантируется.
