Defines the base class that is used when developing managed data flow components.
Namespace: Microsoft.SqlServer.Dts.Pipeline
Assembly: Microsoft.SqlServer.PipelineHost (in Microsoft.SqlServer.PipelineHost.dll)
Syntax
'Declaration
Public Class PipelineComponent
'Usage
Dim instance As PipelineComponent
public class PipelineComponent
public ref class PipelineComponent
type PipelineComponent = class end
public class PipelineComponent
Hinweise
Inherit from this class to create your own data flow component. This class implements the required component interfaces, IDTSDesigntimeComponent100 and IDTSRuntimeComponent100. You override the base class implementation of these methods to provide the functionality of your component. PipelineComponent provides helper methods in addition to the methods of the component interfaces to help you in developing your component.
Beispiele
The following code example shows a component that implements the DtsPipelineComponentAttribute and inherits from the PipelineComponent class.
using System;
using Microsoft.SqlServer.Dts.Pipeline.Wrapper;
namespace Microsoft.Samples.SqlServer.Dts
{
[DtsPipelineComponent(DisplayName="SampleComponent")]
public class SampleComponent : PipelineComponent
{
public override ProvideComponentProperties()
{
// TODO: Implement component intialization.
}
public override DTSValidationStatus Validate()
{
// TODO: Implement component validation.
}
public override void ProcessInput( int inputID, PipelineBuffer buffer)
{
// TODO: For transformation and destination components,
// implement code to process incoming rows.
}
}
}
Imports System
Imports Microsoft.SqlServer.Dts.Pipeline.Wrapper
Namespace Microsoft.Samples.SqlServer.Dts
