using Microsoft.SqlServer.Dts.Runtime;  
  
namespace Executables_API

        {  
            Package pkg = new Package();  
            Executable exec = pkg.Executables.Add("STOCK:BulkInsertTask");  
  
            // Obtain the collection.  
            Executables pgkExecs = pkg.Executables;  
            foreach (Executable eachExec in pgkExecs)  
            {  
                TaskHost th = exec as TaskHost;  
                Console.WriteLine("Executable creation name is: {0}", th.CreationName);  
            }  
  
            // Show use of Contains.  
            if (pgkExecs.Contains(0))  
            {  
                Console.WriteLine("Contains returned true");
