If you are building SSIS 2005 packages programmatically and adding data flow components, you will probably need to know the creation name of the component to add. I can never find a handy reference when I need one, hence this rather mundane post. See also CreationName for SSS 2008.

We start with a very simple snippet for adding a component:

// Add the Data Flow Task 
package.Executables.Add("STOCK:PipelineTask");

// Get the task host wrapper, and the Data Flow task 
TaskHost taskHost = package.Executables[0] as TaskHost;
MainPipe dataFlowTask = (MainPipe)taskHost.InnerObject;

// Add OLE-DB source component - ** This is where we need the creation name **
IDTSComponentMetaData90 componentSource = dataFlowTask.ComponentMetaDataCollection.New();
componentSource.Name = "OLEDBSource";
componentSource.ComponentClassID = "DTSAdapter.OLEDBSource.1"; 

So as you can see the creation name for a OLE-DB Source is DTSAdapter.OLEDBSource.1.

CreationName Reference 

Here is a simple console program that can be used to enumerate the pipeline components installed on your machine, and dumps out a list of all components like that above. You will need to add a reference to the Microsoft.SQLServer.ManagedDTS assembly.

using System;
using System.Diagnostics;
using Microsoft.SqlServer.Dts.Runtime;

public class Program
{
    static void Main(string[] args)
    {
        Application application = new Application();
        PipelineComponentInfos componentInfos = application.PipelineComponentInfos;
        foreach (PipelineComponentInfo componentInfo in componentInfos)
        {
            Debug.WriteLine(componentInfo.Name + "\t" + componentInfo.CreationName);
        }
        Console.Read();
    }
}
