Contoh

Contoh kode berikut menunjukkan bagaimana ConnectionManager properti diatur saat memuat paket secara terprogram.

// TODO: Replace the path to the package with a valid path.  
string package = @"c:\Package.dtsx";  

// Create the application and load the package.  
Application a = new Application();  
Package p = a.LoadPackage( package , null );  

// Walk the Executables collection looking for data flow tasks.  
foreach (Executable e in p.Executables)  
{  
    MainPipe mp = ((TaskHost)e).InnerObject as MainPipe;  
    if( e != null )  
    {  
        // Walk the components.  
        foreach( IDTSComponentMetaData100 md in mp.ComponentMetaDataCollection )  
        {  
            // Walk the RuntimeConnectionCollection.  
            foreach( IDTSRuntimeConnection100 rc in md.RuntimeConnectionCollection )  
            {  
                // Check to see if the package's connections collection contains the   
                // Connectionmanager stored in the RuntimeConnection.  
                if (p.Connections.Contains(rc.ConnectionManagerID))  
                    rc.ConnectionManager = DtsConvert.ToConnectionManager100(p.Connections[rc.ConnectionManagerID]);  
                else  
                    Console.WriteLine("The ConnectionManager " + rc.ConnectionManagerID + " was not found in the Package's Connections collection.");  
            }  
        }  
    }  
}

       If p.Connections.Contains(rc.ConnectionManagerID) Then   
         rc.ConnectionManager = DtsConvert.ToConnectionManager100(p.Connections(rc.ConnectionManagerID))   
       Else   
         Console.WriteLine("The ConnectionManager " + rc.ConnectionManagerID + " was not found in the Package's Connections collection.")   
       End If   
     Next   
   Next   
 End If   
Next  

Keterangan

Properti ConnectionManager berisi, atau set, referensi ke instans aktual objek yang IDTSConnectionManager100 terkandung dalam paket. Pada runtime, referensi ini diatur secara otomatis oleh mesin runtime SSIS menggunakan ConnectionManagerID properti untuk menemukan koneksi dalam paket dan menetapkan referensi.

Pada waktu desain SSIS Designer melakukan penugasan ini saat memuat dan menginisialisasi komponen. Namun, ketika memuat dan mengedit komponen secara terprogram, menggunakan model objek di luar perancang, properti harus diatur secara eksplisit. Komponen tidak memiliki kemampuan untuk mereferensikan koneksi secara eksplisit menggunakan ConnectionManagerID properti karena Connections pengumpulan paket tidak terekspos ke komponen.
