c# - SSIS DTS 脚本任务在用户代码中遇到异常

Question

我正在尝试在 Visual Basic 2010 中执行带有脚本组件的 SSIS 包。执行包时出现以下错误:

    public void Main()
    {
        // TODO: Custom Code starts here
        /*
         * Description: Reads the input CMI Stats files and converts into a more readable format
         * This Code for Better CMI Parser is converted as per SC's original code by S.A. on 3/6/2014
         * Here is the description from original procedure
         * CustType = DOMESTIC/INTERNATIONAL/ETC
         * CategoryType = SBU/MAN
         * Category = Actual value (AI/CC/etc)
         * DataType = INCOMING or SHIP (or something else later?)
         *

         * Uncommented the CAD file load....

谁能建议可能出了什么问题，或者如何调试此代码以了解错误？

谢谢!

这是在 SSIS 中调试脚本的方法

• 打开代码，打断点
• 关闭代码
• 运行包
• 当脚本开始运行时，它会打开一个代码窗口，您可以逐步浏览代码
