Question

更新

我已删除try catch，因此会暴露任何错误。并按语句注释掉语句，最后找到问题陈述

    WB = _Excel.Workbooks.Open("D:\\temp\\TempSSIS\\zip\\test.xlsx",
                        Type.Missing, Type.Missing, Type.Missing, Type.Missing,
                        Type.Missing, Type.Missing, Type.Missing, Type.Missing,
                        Type.Missing, Type.Missing, Type.Missing, Type.Missing,
                        Type.Missing, Type.Missing);

但不知道为什么。文件夹D：\ temp和所有文件或文件夹已经与具有读/写权限的所有人共享。

以下是SSIS目录执行报告的图片 enter image description here

我有一个测试SSIS（SQL Server 2012）项目，它有一个包，只有一个脚本任务。在此脚本任务中：

该脚本打开现有的Excel文件并为excel添加密码。这在VS中工作正常，但是当我从SQL Server作业代理运行它时失败。该作业在sql server代理帐户上运行，该帐户可以访问该文件。来自作业代理的错误消息：

我在Integration Services目录的报告中找到的唯一内容是脚本任务：错误：调用目标已抛出异常。
