Question

我正在使用MSBuild副本，然后使用Concat连接多个SQL文件。一些SQL文件采用其他格式（在记事本中打开），但在Concat访问文件后，生成的文件中都会出现奇怪的字符。

任何人都可以帮助我，有没有人经历过这个？如何将所有SQL文件转换为ascii，或使Concat任务正常工作？

Answer 1

我通过编写实用程序C＃类来解决它。它不是为处理异常而设计的，它们由调用类处理或在控制台中未处理。

它将文件转换为ASCII，删除所有无效字符并重写文件。

我花了一段时间想知道为什么我会收到拒绝访问权限的问题，请确保在转换之前检出所有要转换的文件！

MSBuild Concat任务仅处理ASCII文件
