將現有的容器或任務物件加入集合。Executables
public:
void Join(Microsoft::SqlServer::Dts::Runtime::Executable ^ executable);
public void Join(Microsoft.SqlServer.Dts.Runtime.Executable executable);
member this.Join : Microsoft.SqlServer.Dts.Runtime.Executable -> unit
Public Sub Join (executable As Executable)
參數
- executable
- Executable
容器或任務的現有 TaskHost 名稱。
範例
以下範例建立一個 Bulk Insert 任務並設定一些屬性。 接著,Bulk Insert 任務會從第一個套件中移除,並加入第二個套件。 在第一個套件中設定的屬性保持不變。

using System.Collections.Generic;
using System.Text;
using Microsoft.SqlServer.Dts.Runtime;
using Microsoft.SqlServer.Dts.Tasks.BulkInsertTask;
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");
TaskHost myTask = exec as TaskHost;
BulkInsertTask myBI = myTask.InnerObject as BulkInsertTask;
myBI.DebugMode= false;
myBI.CheckConstraints = false;
myBI.KeepIdentity = true;
// Obtain the collection.
Executables pgkExecs = pkg.Executables;
// Show the number of executables in the collection.
Console.WriteLine("The first package contains {0} executables", pgkExecs.Count);
// It is a requirement to Remove the task from the
// existing package before adding it to the new package.
pkg.Executables.Remove(0);
// Show the number of executables in the collection afterwards.
Console.WriteLine("The first package now contains {0} executables", pgkExecs.Count);
Package pkg2 = new Package();
Executables p2Execs = pkg2.Executables;
// Show the number of executables in the second collection.
Console.WriteLine("The second package initially contains {0} executables", p2Execs.Count);
// Join the task from pkg to pkg2.
pkg2.Executables.Join(myTask);
// Show the number of executables in the second collection after Join.
Console.WriteLine("The second package now contains {0} executables", p2Execs.Count);
}

' Show the number of executables in the second collection after Join.
Console.WriteLine("The second package now contains {0} executables", p2Execs.Count)
End Sub
End Class
End Namespace
範例輸出:
The first package contains 1 executables
The first package now contains 0 executables
The second package initially contains 0 executables
The second package now contains 1 executables
備註
當你將容器或任務從一個容器(來源)移動到另一個(目的地)時使用 Join 。 你必須先從來源容器 Remove 移除物件,才能呼叫 Join 目的地。
