	BufferManager	Gets the IDTSBufferManager100 object. (Производный от IDTSPipeline100.)
	BufferTempStoragePath	Gets or sets the file system path used to temporarily cache buffer data. (Производный от IDTSPipeline100.)
	ComponentMetaDataCollection	Gets the collection of data flow components in the task. (Производный от IDTSPipeline100.)
	DefaultBufferMaxRows	Gets or sets the maximum number of rows the task allows in an IDTSBuffer100 buffer. (Производный от IDTSPipeline100.)
	DefaultBufferSize	Gets or sets the default size of the IDTSBuffer100 objects created by the task. (Производный от IDTSPipeline100.)
	EnableCacheUpdate	Инфраструктура. Gets or sets whether the IDTSPipeline100 enabled the updating of cache. (Производный от IDTSPipeline100.)
	EnableDisconnectedColumns	Gets or sets a value that indicates whether the data flow task enables the disconnected columns in the main pipe. (Производный от IDTSPipeline100.)
	EngineThreads	Gets or sets the number of threads the data flow task uses. (Производный от IDTSPipeline100.)
	Events	Sets the events interface that the data flow and its components use to raise events during execution. (Производный от IDTSPipeline100.)
	IsSavingXml	Инфраструктура. Gets or sets whether the IDTSPipeline100 is saving xml. (Производный от IDTSPipeline100.)
	PathCollection	Gets the IDTSPathCollection100 collection for the data flow task. (Производный от IDTSPipeline100.)

Методы

	Имя	Описание
	GetNextPasteID	Gets the next available ID that the data flow task generates. (Производный от IDTSPipeline100.)

Замечания

The MainPipe (displayed as the Data Flow Task in SQL Server Data Tools (SSDT)) is the managed implementation of the IDTSPipeline100 COM interface. It is the interface used from managed code when programmatically creating or modifying a data flow task in a Package. For an overview of the methods and properties available to this object, see the MainPipeClass documentation.

Примеры

The following code example adds the MainPipe object to a Package and retrieves the MainPipe using the InnerObject property of the TaskHost.

Package p = new Package();
Executable e = p.Executables.Add("DTS.Pipeline.1");
TaskHost thMainPipe = e as TaskHost;
MainPipe dataFlowTask = thMainPipe.InnerObject as MainPipe;
