Example

The following code example creates a ForEachEnumeratorHost to hold a ForEachSMOEnumerator enumerator, and displays the host properties.

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

namespace Microsoft.SqlServer.SSIS.Sample
{
    internal class EnumType
    {
        public const string SMOEnum = "Foreach SMO Enumerator";
    }
    class Program
    {
        static void Main(string[] args)
        {
            Application app = new Application();
            ForEachEnumeratorInfos infos = app.ForEachEnumeratorInfos;
            ForEachEnumeratorInfo info = null;

            foreach (ForEachEnumeratorInfo enumInfo in infos)
            {
                Console.Write("Available enumerators: {0}\n", enumInfo.Name);
                if (enumInfo.Name == EnumType.SMOEnum)
                {
                    // Set the ForEachEnumeratorInfo variable
                    // to the SMo enumerator, and use it 
                    // later in the CreateNew method.
                    info = enumInfo;
                }
        }
            ForEachEnumeratorHost enumH = info.CreateNew();
            Console.WriteLine();
            Console.WriteLine("Host InnerObject: " + enumH.InnerObject.ToString());
            Console.WriteLine("CollectionEnumerator? {0}", enumH.CollectionEnumerator);
            Console.WriteLine("CreationName: {0}",  enumH.CreationName);
            Console.WriteLine("Description:  {0}", enumH.Description);

        }
    }
