Примеры

The following code example creates a package and adds a Bulk Insert task. It then gets the Properties, and views the Get and Set property values along with the property name.

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

namespace Executables_API
{
    class Program
    {
        static void Main(string[] args)
        {
            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);
