Свойства

	Имя	Описание
	Buffer	Gets the ID of a PipelineBuffer that is allocated for an IDTSInput100 object and provided to the component in the ProcessInput method.
	BufferBase	Инфраструктура.
	Component	Gets the IDTSComponentMetaData100 of an IDTSInput100 object.
	CustomPropertyCollection	Gets the IDTSCustomPropertyCollection100 object of an IDTSInput100 object.
	Dangling	Gets or sets a value that notifies the data flow engine that the input can be unattached.
	Description	Gets or sets the description of an IDTSInput100 object.
	Description	Gets or sets the description of an IDTSObject100. (Производный от IDTSObject100.)
	ErrorOrTruncationOperation	Gets or sets a String that specifies the types of errors or truncations that can occur while processing a PipelineBuffer row.
	ErrorRowDisposition	Gets or sets a value from a DTSRowDisposition enumeration that specifies how the component will handle error conditions that occur when processing a row from a PipelineBuffer object.
	ExternalMetadataColumnCollection	Gets the collection of columns that reflects the columns in an external data source, which are used to validate an IDTSInputColumnCollection100 when the component is not connected to the external data source.
	HasSideEffects	Gets or sets a value that indicates whether a data flow component should be removed or remain in the execution plan of a data flow task when its output is not attached to a downstream component and when the RunInOptimizedMode property of the Data Flow task is true.

	InputColumnCollection	Gets the IDTSInputColumnCollection100 of an IDTSInput100 object.
	IsAttached	Gets a value that indicates if an IDTSInput100 is attached to an upstream component through an IDTSPath100 object.
	IsSorted	Gets a value that indicates whether the columns in an IDTSInputColumnCollection100 are sorted.
	Name	Gets or sets the name of an IDTSInput100 object.
	Name	Gets or sets the name of an IDTSObject100 object. (Производный от IDTSObject100.)

Замечания

The IDTSInput100 object represents a connection point between two components, and, when connected to the IDTSOutput100 of an upstream component, establishes the flow of data between components. A connection between an IDTSInput100 and an IDTSOutput100 is established through the IDTSPath100 object. The input represents the EndPoint property of the IDTSPath100 object.

At design time, the columns in the IDTSOutputColumnCollection100 of the output that the input is connected to are selected for use by the component. These columns are then available to the component during component execution.

Примеры

The following code example demonstrates a component adding an input to its collection in the ProvideComponentProperties method.

using System;
using Microsoft.SqlServer.Dts.Pipeline;
public class DtsSampleComponent : PipelineComponent
{ 
public override void ProvideComponentProperties()
{
IDTSInput100 input = ComponentMetaData.InputCollection.New();
input.Name = "SampleComponentInput0";
}
}

Imports System 
Imports Microsoft.SqlServer.Dts.Pipeline 

Public Class DtsSampleComponent 
Inherits PipelineComponent 

 Public Overloads Overrides Sub ProvideComponentProperties() 
   Dim input As IDTSInput100 = ComponentMetaData.InputCollection.New 
   input.Name = "SampleComponentInput0" 
 End Sub 
End Class
