属性值

The IDTSComponentMetaDataCollection90 collection.

备注

This collection contains the data flow components that have been added to the task. Components are created and added to the collection by calling the New method.

示例

The following code example shows how to add and initialize a new component in the collection.

using System;
using Microsoft.SqlServer.Dts.Runtime;
using Microsoft.SqlServer.Dts.Pipeline.Wrapper;

namespace Microsoft.Samples.SqlServer.Dts
{
    public class Class1
    {
        public static void Main( string []args )
        {
            Package p = new Package();
            MainPipe mp = ((TaskHost)p.Executables.Add("DTS.Pipeline")).InnerObject as MainPipe;
            IDTSComponentMetaData90 md = mp.ComponentMetaDataCollection.New();
            md.ComponentClassID = "DTSAdapter.OleDbSource";
            CManagedComponentWrapper wrp = md.Instantiate();
            wrp.ProvideComponentProperties();
        }
    }
}

Imports System 
Imports Microsoft.SqlServer.Dts.Runtime 
Imports Microsoft.SqlServer.Dts.Pipeline.Wrapper 
Namespace Microsoft.Samples.SqlServer.Dts 

 Public Class Class1 

   Public Shared Sub Main(ByVal args As String()) 
     Dim p As Package = New Package 
     Dim mp As MainPipe = CType(CType(p.Executables.Add("DTS.Pipeline"), TaskHost).InnerObject, MainPipe) 
     Dim md As IDTSComponentMetaData90 = mp.ComponentMetaDataCollection.New 
     md.ComponentClassID = "DTSAdapter.OleDbSource" 
     Dim wrp As CManagedComponentWrapper = md.Instantiate 
     wrp.ProvideComponentProperties 
   End Sub 
 End Class 
End Namespace
