Visual Studio 中的多个预构建事件？
我关注了 Scott Hanselman 的一篇博客文章 使用预构建事件管理配置 并拥有它工作正常。
我现在想将配置分成几个不同的文件，因此需要在构建之前再次执行该命令。问题是 PreBuild 事件文本全部作为一个控制台命令执行。如何将其拆分为多个命令？
I've followed a blog post by Scott Hanselman for managing configuration with PreBuild Events and have it working fine.
I now want to split up my configuration into a couple of different files, so need to exectue the command again before the build. The problem is the PreBuild event text all gets executed as one console command. How can I split it up as several commands?

事实证明，问题是 Scott 的示例在行开头不包含
call命令。只要您不想使用不同的参数多次执行.bat文件，就可以了。这：
对我来说效果很好。
Turns out the problem is Scott's example doesn't include the
callcommand at the start of the line. This is fine as long as you don't want to execute the.batfile multiple times with different parameters.This:
worked fine for me.
我在 Windows 7 64 位上使用 Visual Studio 2010。
我找到了一个更符合我喜好的解决方案，我将命令与
&& 链接在一起^，例如，像这样编辑我的 .vcxproj xml 文件：我将三个命令链接在一起。 “&&”如果前一个命令出错，则告诉 shell 停止执行。
请注意，在 .xml 文件中，不能直接使用
&&，因此 '& ＆amp;＆amp;必须使用 amp;' 来代替。另请注意^字符的使用，这是 cmd shell 的行继续字符（如 BASH 的\字符）。每个新命令必须从行首开始。使用这种方法，人们可以根据需要链接任意数量的命令，但如果任何命令失败，则链中的其余命令将不会被执行。
例，我使用 Python 脚本执行一些环境检查，然后将预编译头的调试文件复制到另一个子项目的目录：
这是我的实际用 在复制命令上使用 nul 可防止在构建窗口中显示任何输出，因此当它显示
0 个文件已复制时，我的队友不会被吓到。参考共享 pre - 子项目之间的编译标头位于：

I'm using Visual Studio 2010 on Windows 7 64-bits.
I found a solution that's better to my liking, I'm chaining commands together with
&& ^, for example, editing my .vcxproj xml file like so:I've chained three commands together. The '&&' tells the shell to stop executing if the previous command errors out.
Note, in the .xml file, one can't use
&&directly, so '& amp;& amp;' must be used instead. Also note the use of the^character, this is the cmd shell's line continuation character (like BASH's\char).Each new command must start at the beginning of the line. Using this approach, one can chain as many commands as one wants, but if any fail, the rest in the chain won't get executed.
Here's my actual usecase, I'm performing some environment checks with a Python script, followed by copying my pre-compiled header's debug file to another sub-project's directory:
The
> nulusage on the copy command prevents any output showing up in the build window, so my teammates won't get freaked out when it says0 file(s) copied.Reference to sharing pre-compiled headers between sub-projects is here:

您应该能够将命令放在单独的行上，然后每个命令将按顺序执行。或者，执行相同操作的“作弊”方法如下：
You should be able to put the commands on a separate line, and then each command will be executed in sequence. Alternatively, a "cheater" way to do the same thing is as follows:
