Osservazioni

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.

Esempi

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("SSIS.Pipeline.2")).InnerObject as MainPipe;
            IDTSComponentMetaData100 md = mp.ComponentMetaDataCollection.New();
            md.ComponentClassID = "DTSAdapter.OleDbSource";
            CManagedComponentWrapper wrp = md.Instantiate();
            wrp.ProvideComponentProperties();
        }
    }
}

     Dim md As IDTSComponentMetaData100 = mp.ComponentMetaDataCollection.New 
     md.ComponentClassID = "DTSAdapter.OleDbSource" 
     Dim wrp As CManagedComponentWrapper = md.Instantiate 
     wrp.ProvideComponentProperties 
   End Sub
