using System;
using System.Collections;
using System.Collections.Generic;
using System.Text;
using Microsoft.SqlServer.Dts.Runtime;
using Microsoft.SqlServer.Dts.Runtime.Enumerators.Item;

namespace ForEachEnums
{
    class Program
    {
        static void Main(string[] args)
        {
            Application app = new Application();
            ForEachEnumeratorInfos feInfos = app.ForEachEnumeratorInfos;

            // Search the collection by name.
            if (feInfos.Contains("For Each File Enumerator"))
                Console.WriteLine("The collection contains {0} enumerator", feInfos[0].Name);
            else
                Console.WriteLine("The collection does not contain {0} enumerator", feInfos[0].Name);
        }
    }
