如何将 FireError 用于 SSIS 任务脚本？

Question

以下 SSIS 任务脚本应该将数据插入到三个表中，但是该脚本仅在本地工作，而不在服务器上工作。 我想使用 FireError() / FireInformation 来调试并找出原因。 我的问题是我不知道如何为此脚本编写 FireError。 你能不能给我一个小例子/提示或任何你想称呼它的东西，以便我可以将它应用到我的代码中。

https://stackoverflow.com/a/28907522/181965的示例代码演示了脚本任务与脚本组件（您正在使用）方法签名之间的差异

    bool fireAgain = false;
    this.Dts.Events.FireInformation(0, "my sub", "info", string.Empty, 0, ref fireAgain);
    // Note, no cancel available
    this.Dts.Events.FireError(0, "my sub", "error", string.Empty, 0);

至于您将其放入现有代码的位置，我不知道您的设计目标是什么，但我认为它适合您的 ErrorBuffer 调用所在的位置 - 尽管 FireError 会破坏处理，所以可能不会？ 也许您想将所有坏行累积到一个全局变量中，并在PostEvent部分中枚举它们，以便查看所有坏行。 /耸耸肩
