Значение свойства

The IDTSConnectionManager90 of the component.

Замечания

The ConnectionManager property contains, or sets, a reference to the actual instance of the IDTSConnectionManager90 object contained in the package. At runtime, this reference is set automatically by the SSIS runtime engine using the ConnectionManagerID property to locate the connection in the package and assign a reference.

At design time the SSIS Designer does this assignment when loading and initializing a component. However, when programmatically loading and editing a component, using the object model outside of the designer, the property must be set explicitly. Components do not have the ability to reference the connection explicitly using the ConnectionManagerID property because the Connections collection of the package is not exposed to components.

Пример

The following code example shows how the ConnectionManager property is set when programmatically loading a package.

// 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( IDTSComponentMetaData90 md in mp.ComponentMetaDataCollection )
        {
            // Walk the RuntimeConnectionCollection.
            foreach( IDTSRuntimeConnection90 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.ToConnectionManager90(p.Connections[rc.ConnectionManagerID]);
                else
                    Console.WriteLine("The ConnectionManager " + rc.ConnectionManagerID + " was not found in the Package's Connections collection.");
            }
        }
    }
}

' TODO: Replace the path to the package with a valid path.
Dim package As String = "c:\Package.dtsx" 

' Create the application and load the package.
Dim a As Application = New Application 
Dim p As Package = a.LoadPackage(package, Nothing) 

' Walk the Executables collection looking for data flow tasks.
For Each e As Executable In p.Executables 
 Dim mp As MainPipe = CType(CType(e, TaskHost).InnerObject, MainPipe) 
 If Not (e Is Nothing) Then 
   ' Walk the components.
   For Each md As IDTSComponentMetaData90 In mp.ComponentMetaDataCollection 
     ' Walk the RuntimeConnectionCollection.
     For Each rc As IDTSRuntimeConnection90 In md.RuntimeConnectionCollection 
       ' Check to see whether the package's connections collection  
       '  contains the Connectionmanager stored in the RuntimeConnection.
       If p.Connections.Contains(rc.ConnectionManagerID) Then 
         rc.ConnectionManager = DtsConvert.ToConnectionManager90(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
