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