Примеры
The following code example adds a Bulk Insert task to a package, creates an Executables collection, creates the enumerator, and shows the name of the task using the 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();
}
}
}

Console.WriteLine("The collection contains the following values:")
Dim i As Integer = 0
Dim myExec As Executable
Dim myTH As TaskHost
While (myEnumerator.MoveNext()) &&(myEnumerator.Current <> Nothing)
myExec = CType(myEnumerator.Current, Executable)
myTH = CType(myExec, TaskHost)
Console.WriteLine("[{0}] {1}",i = Console.WriteLine("[{0}] {1}",i + 1
End While
' Reset puts the index pointer before the beginning.
' Do not retrieve from the collection until MoveNext is called.
myEnumerator.Reset()
myEnumerator.MoveNext()
End Sub
End Class

Sample Output:
The collection contains the following values:
[0] {C435F0C7-97E8-4DCC-A0FF-C6C805D9F64E}
