CManagedComponentWrapperClass 类

定义

Microsoft.SqlServer.Dts.Pipeline.Wrapper.Sql2012

Microsoft.SqlServer.DTSPipelineWrap.dll

示例

以下代码示例将组件添加到数据流任务中，并通过调用实例化方法检索CManagedComponentWrapper接口的实例。

Package p = new Package();  
MainPipe mp = ((TaskHost)p.Executables.Add("DTS.Pipeline")).InnerObject as MainPipe;  

IDTSComponentMetaData100 md = mp.ComponentMetaDataCollection.New();  
md.ComponentClassID = "DTSAdapter.OleDbSource";  

CManagedComponentWrapper wrp = md.Instantiate();

注解

CManagedComponentWrapperClass 代表数据流组件的设计实例，是数据流任务中程序性修改组件时使用的对象。 该类的方法由IDTSDesigntimeComponent100接口定义，用于修改属性和集合组件。 当调用组件的IDTSComponentMetaData100接口的实例化方法时，返回CManagedComponentWrapper接口。 该接口可以投射为CManagedComponentWrapperClass的实例，但这样做没有优势。 因此，通常不使用该类。
