Script Task Examples

更新： 2006 年 4 月 14 日

The Script task is a multi-purpose tool that you can use in a package to fill almost any requirement that is not met by the tasks included with Integration Services. This topic lists Script task code samples that demonstrate some of the available functionality.

附註：
If you want to create tasks that you can more easily reuse across multiple packages, consider using the code in these Script task samples as the starting point for custom tasks. For more information, see Developing a Custom Task.
