注释
Data flow components are added to the MainPipe class by calling the New method of the ComponentMetaDataCollection.
示例
The following code example adds an OLE DB Source component to a data flow task by calling the New method of the MainPipe class.
using System;
using Microsoft.SqlServer.Dts.Runtime;
using Microsoft.SqlServer.Dts.Pipeline.Wrapper;
namespace Microsoft.Samples.SqlServer.Dts
{
class CreateComponent
{
[STAThread]
static void Main(string[] args)
{
// Create the package.
Package p = new Package();
// Add the data flow task to the package.
MainPipe dataFlowTask = ((TaskHost)p.Executables.Add("DTS.Pipeline.1")).InnerObject as MainPipe;
if (dataFlowTask != null)
{
// Add a component to the data flow task.
IDTSComponentMetaData100 metaData = dataFlowTask.ComponentMetaDataCollection.New();
// Set the class ID of the component.
metaData.ComponentClassID = "DTSAdapter.OLEDBSource.1";
// Create an instance of the component.
CManagedComponentWrapper wrapper = metaData.Instantiate();
// Initialize the component.
wrapper.ProvideComponentProperties();
}
}
}
