Exemplos

O exemplo de código a seguir adiciona uma tarefa Bulk Insert a um pacote, cria uma Executables coleção, cria o enumerador e mostra o nome da tarefa usando o TaskHost.

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

namespace Executables_API  
{  
    class Program  
    {  
        static void Main(string[] args)  
        {  
            // Create the package and add the BulkInsertTask.  
            Package pkg = new Package();  
            Executable exec = pkg.Executables.Add("STOCK:BulkInsertTask");  

            // Obtain the collection.  
            Executables pgkExecs = pkg.Executables;  

            //Create the Enumerator.  
            ExecutableEnumerator myEnumerator = pgkExecs.GetEnumerator();  
            Console.WriteLine("The collection contains the following values:");  
            int i = 0;  
            Executable myExec;  
            TaskHost myTH;  
            while ((myEnumerator.MoveNext()) && (myEnumerator.Current != null))  
            {  
                myExec = (Executable)myEnumerator.Current;  
                myTH = (TaskHost)myExec;  
                Console.WriteLine("[{0}] {1}", i++, myTH.Name);  
            }  
            // Reset puts the index pointer before the beginning.  
            // Do not retrieve from the collection until MoveNext is called.  
            myEnumerator.Reset();  
            myEnumerator.MoveNext();  

        }  
    }  
}
