Exemplos
O exemplo a seguir é uma modificação do exemplo encontrado em Remover. Ele remove o executável usando a sintaxe do item.

using System.Collections.Generic;
using System.Text;
using Microsoft.SqlServer.Dts.Runtime;
using Microsoft.SqlServer.Dts.Tasks.BulkInsertTask;
namespace Executables_API
{
class Program
{
static void Main(string[] args)
{
Executable exec = pkg.Executables.Add("STOCK:BulkInsertTask");
TaskHost myTask = exec as TaskHost;
BulkInsertTask myBI = myTask.InnerObject as BulkInsertTask;
myBI.DebugMode = false;
myBI.CheckConstraints = false;
myBI.KeepIdentity = true;
// Obtain the collection.
Executables pgkExecs = pkg.Executables;
// Show the number of executables in the collection.
Console.WriteLine("The first package contains {0} executables", pgkExecs.Count);
// It is a requirement to Remove the task from the
// existing package before adding it to the new package.
// Remove the exectuable using the Executables[x] item syntax.
DtsContainer c = (DtsContainer)pkg.Executables[0];
pkg.Executables.Remove(c);
// Show the number of executables in the collection afterwards.
Console.WriteLine("The first package now contains {0} executables", pgkExecs.Count);
Package pkg2 = new Package();
Executables p2Execs = pkg2.Executables;
// Show the number of executables in the second collection.
Console.WriteLine("The second package initially contains {0} executables", p2Execs.Count);
// Join the task from pkg to pkg2.
pkg2.Executables.Join(myTask);
// Show the number of executables in the second collection after Join.
Console.WriteLine("The second package now contains {0} executables", p2Execs.Count);
}
}

Saída de exemplo:
The first package contains 1 executables
The first package now contains 0 executables
The second package initially contains 0 executables
The second package now contains 1 executables
Comentários
Se a chamada para o Contains método retornar true
, você poderá acessar o elemento especificado na coleção usando a sintaxe Executables[index]
. Se a Contains propriedade retornar false
, essa propriedade gerará uma exceção. Em C#, essa propriedade é o indexador da classe Executables.
