我正在尝试构建一个将在标准化文件系统存档过程中使用的 SSIS 包。基本上,我将能够将信息添加到配置表中,然后使用该表将某些文件存档在指定文件夹中。我的问题是很多文件都有动态命名,所以我需要获取所有文件的列表,然后查询以确定我应该接触哪些文件。
不是 C#/VB 程序员在尝试编写包的一部分脚本以获取指定网络目录中的所有文件然后将这些文件名反馈回 SSIS 对象变量时给我带来了一些问题。
我有一个字符串变量“User::SourceNetworkFolderName”,它将包含我要从中读取所有文件的文件夹的 UNC 位置。然后我想将所有这些文件名(带扩展名)传递回一个名为“User::SourceFilesInTheDirectory”的 SSIS 对象变量。一旦我将文件名列表放入对象变量中,我将 foreach 将它们循环到 SQL 表中。
有没有人对我如何从我的变量目录中获取所有文件名的列表到我的 SSIS 对象变量有任何具体建议?
先感谢您!
