示例

下面的代码示例演示一个组件，该组件实现 DtsPipelineComponentAttribute 并继承自 PipelineComponent 该类。

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   

 <DtsPipelineComponent(DisplayName="SampleComponent")> _   
 Public Class SampleComponent   
 Inherits PipelineComponent   

   Public Overrides Sub ProvideComponentProperties()   
    ' TODO: Implement component intialization.  
   End Sub   

   Public Overrides Function Validate() As DTSValidationStatus   
    ' TODO: Implement component validation.  
   End Function   

   Public Overrides Sub ProcessInput(ByVal inputID As Integer, ByVal buffer As PipelineBuffer)   
    ' TODO: For transformation and destination components,  
    '  implement code to process incoming rows.  
   End Sub   
 End Class   
End Namespace  

注解

继承自此类以创建自己的数据流组件。 此类实现所需的组件接口和 IDTSDesigntimeComponent100IDTSRuntimeComponent100。 重写这些方法的基类实现，以提供组件的功能。 PipelineComponent 除了组件接口的方法外，还提供帮助程序方法，以帮助你开发组件。
