示例

下面的代码示例演示如何在以编程方式加载包时设置 ConnectionManager 属性。

// 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.");  
            }  
        }  
    }  
}  

' 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 IDTSComponentMetaData100 In mp.ComponentMetaDataCollection   
     ' Walk the RuntimeConnectionCollection.  
     For Each rc As IDTSRuntimeConnection100 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.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  

注解

ConnectionManager 属性包含或设置对包中包含的对象的实际实例的 IDTSConnectionManager100 引用。 在运行时，SSIS 运行时引擎使用 ConnectionManagerID 属性在包中定位连接并分配引用，自动设置此引用。

在设计时，SSIS 设计器在加载和初始化组件时执行此分配。 但是，当以编程方式加载和编辑组件时，必须使用设计器外部的对象模型显式设置该属性。 组件不能使用 ConnectionManagerID 属性显式引用连接，因为 Connections 包的集合不会向组件公开。
