備註

All containers, including the Package, Sequence, TaskHost, DtsEventHandler, ForLoop, and ForEachLoop, have an Executables property that contains the collection of executable objects processed by the run-time engine during execution of the container. The order of execution of the objects in the collection is determined by the PrecedenceConstraints inherited and implemented by the containers. You can add tasks to a package and set their properties graphically using the SSIS Designer, or programmatically using the run-time object model to build the package in Microsoft Visual Basic, Microsoft Visual C++, or C#.

執行緒安全性

這個型別的任何公用 static (在 Visual Basic 中為 Shared) 成員都是執行緒安全的。並不是所有的執行個體成員都保證可以用於所有的執行緒。
