예

The following code example adds the Bulk Insert task as an executable, then uses Contains to verify the existance of at least one executable in the package.

using System;
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);
            }

            // Show use of Contains.
            if (pgkExecs.Contains(0))
            {
                Console.WriteLine("Contains returned true");
            }
            else
            {
                Console.WriteLine("Contains returned false");
            }
        }
    }
}

Imports System
Imports System.Collections.Generic
Imports System.Text
Imports Microsoft.SqlServer.Dts.Runtime
 
Namespace Executables_API
        Class Program
        Shared  Sub Main(ByVal args() As String)
            Dim pkg As Package =  New Package() 
            Dim exec As Executable =  pkg.Executables.Add("STOCK:BulkInsertTask") 
 
            ' Obtain the collection.
            Dim pgkExecs As Executables =  pkg.Executables 
            Dim eachExec As Executable
            For Each eachExec In pgkExecs
                Dim th As TaskHost =  exec as TaskHost 
                Console.WriteLine("Executable creation name is: {0}", th.CreationName)
            Next
 
            ' Show use of Contains.
            If pgkExecs.Contains(0) Then
                Console.WriteLine("Contains returned true")
            Else 
                Console.WriteLine("Contains returned false")
            End If
        End Sub
        End Class
End Namespace

Sample Output:

Executable creation name is: Microsoft.SqlServer.Dts.Tasks.BulkInsertTask.BulkInsertTask, Microsoft.SqlServer.BulkInsertTask, Version=10.0.000.0, Culture=neutral, PublicKeyToken=89845dcd8080cc91

Contains returned true
