範例
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");
}
}
}
}

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=9.0.242.0, Culture=neutral, PublicKeyToken=89845dcd8080cc91
