方法

	名称	说明
	AcquireConnections	Establishes a connection to a connection manager.
	DeleteExternalMetadataColumn	Deletes the external metadata column at the specified index from the collection of external metadata columns.
	DeleteInput	Deletes an IDTSInput100 object from the IDTSInputCollection100 collection.
	DeleteOutput	Deletes an IDTSOutput100 object from the IDTSOutputCollection100 collection.
	DeleteOutputColumn	Deletes an IDTSOutputColumn100 object from the IDTSOutputColumnCollection100 collection.
	DescribeRedirectedErrorCode	Returns the description of the specified error code.
	GetEnumerationCollection	Returns the IDTSFriendlyEnumCollection100 of a component.
	InsertExternalMetadataColumnAt	Inserts a new external metadata column into the collection of external metadata columns at the specified index.
	InsertInput	Adds an IDTSInput100 object to the IDTSInputCollection100.
	InsertOutput	Adds a new IDTSOutput100 object.
	InsertOutputColumnAt	Creates a new IDTSOutputColumn100 object and inserts it into the IDTSOutputColumnCollection100.
	MapInputColumn	Establishes a relationship between an input column and a corresponding external metadata column.
	MapOutputColumn	Establishes a relationship between an output column and a corresponding external metadata column.
	OnDeletingInputColumn	Called when deleting an IDTSInputColumn100 object from the IDTSInputColumnCollection100.
	OnInputPathAttached	Called when an IDTSInput100 object is connected to another component through the IDTSPath100 interface.
	OnInputPathDetached	Called when an IDTSPath100 object that contains the specified IDTSInput100 object is deleted.
	OnOutputPathAttached	Called when an IDTSOutput100 object of the component is attached to a downstream component.
	ProvideComponentProperties	Initializes the ComponentMetaData of the component when a component is first added to the data flow task.
	ReinitializeMetaData	Fixes any errors identified during design-time validation that result in the component returning VS_NEEDSNEWMETADATA.
	ReleaseConnections	Frees the connections established during AcquireConnections at either design time or run time.
	SetComponentProperty	Assigns a value to an IDTSCustomProperty100 of a component.
	SetExternalMetadataColumnDataTypeProperties	Sets the data type properties of the specified external metadata column.
	SetExternalMetadataColumnProperty	Sets an individual property of an external metadata column.
	SetInputColumnProperty	Assigns a value to the IDTSCustomProperty100 of an IDTSInputColumn100 object.
	SetInputProperty	Assigns a value to the IDTSCustomProperty100 of an IDTSInput100 object.

注释

This interface is one of two interfaces implemented by data flow components; IDTSRuntimeComponent100 is the other. This interface defines the design-time interface for a component and contains methods that are called when the component properties and collections of the ComponentMetaData are modified. Managed component developers do not explicitly implement this interface, and instead use the PipelineComponent base class, which implements the methods of both these interfaces.

When programmatically adding or modifying existing components in a data flow task, the design-time instance of a component should be used instead of accessing the component metadata directly. Modifying the ComponentMetaData directly bypasses the ability of the component to validate and reject changes to its metadata, and should be avoided. Managed code developers access the design-time instance of a component, and use the methods of the IDTSDesigntimeComponent100 interface, through the CManagedComponentWrapper.

示例

The following code example demonstrates how to access the design-time instance of a component.

Package p = new Package();
MainPipe dataFlow = ((TaskHost)p.Executables.Add("SSIS.Pipeline.2")).InnerObject as MainPipe;

IDTSComponentMetaData100 md = dataFlow.ComponentMetaDataCollection.New();
md.ComponentClassID = "DTSAdapter.OleDbSource";
CManagedComponentWrapper wrp = md.Instantiate();
wrp.ProvideComponentProperties();

Dim p As Package = New Package 
Dim dataFlow As MainPipe = CType(CType(p.Executables.Add("SSIS.Pipeline.2"), TaskHost).InnerObject, MainPipe) 
Dim md As IDTSComponentMetaData100 = dataFlow.ComponentMetaDataCollection.New 
md.ComponentClassID = "DTSAdapter.OleDbSource" 
Dim wrp As CManagedComponentWrapper = md.Instantiate 
wrp.ProvideComponentProperties
