问题： 有一个构建我们的可执行文件的过程。在运行 setup/deploy 项目的构建之前，我构建了需要包含在 setup/deploy 项目的 FileSystem/Common Documents 文件夹中的文件。如果文件名总是被创建为相同的文件名，这很简单；但是，我有一个无法预先确定文件名的情况，因为该过程可以并且将在每次连续运行时创建一个唯一的文件名。
问题： 如何以编程方式将文件添加到 FileSystem/Common Documents 文件夹？
我的研究： 我研究了自定义操作，但不确定如何引用设置/部署项目的文件系统，以便我可以添加这些文件。
更多细节 作为我们日常构建过程的一部分，我们创建http://lucene.apache.org/ (Lucene) 索引，其中 *.cfs 形式的文件可以具有与前一天不同的文件名。由于我们不希望在 Visual Studio 中打开 vdproj 文件并使用文件系统编辑器手动替换文件名，因此我们需要一种更自动化的方法。
我们的解决方案 作为解决方案，我使用了http://www.ewaldhofman.nl/post/2011/04/06/Customize-Team-Build-2010-e28093-Part-16-Specify-the-relative-reference-path。 aspx（Ewald Hofman 的）关于 TFS Team Build 的优秀教程。在此，我复制了他的签出活动和签入活动，同时添加了我自己的自定义活动，该活动打开 vdproj 文件并根据预生成的 Lucene 索引文件名编辑文件。

{
//read the vdproj file into memory
string text = File.ReadAllText(fileFullName);
//for each lucene index folder
foreach (string index in indexerNames)

//traversing twice so that the lucene index and spell index can be handled
//these are subfolder names we use to segregate our normal lucene index from our spelling indexes.
