问题描述
我试图创造一个VS2010后生成的文件复制步骤，处理路径宏时，他们已嵌入空格。我试过在双引号周围的复制命令，但我得到的时候，如果 $（SolutionDir）包含空格副本调用错误。在错误信息回显命令行不显示双引号。
I'm trying to create a post build file copy step in VS2010 which handles path macros when they have embedded spaces. I've tried surrounding the copy commands in double quotes but I get error from when copy is invoked if $(SolutionDir) contains a space. the echoed command line in the error message does not show the double quotes.
复制$（SolutionDir）$（配置）\\ *，$（TARGETDIR）
我也分开审讯 \\和，但是这两个导致2个字符转义序列出现在呼应命令行？一个人如何正确转义双引号在构建步骤？
I also tried separately \" and "" but both of these cause the 2 character escape sequence to appear in the echoed command line? How does one properly escape a double quote in a build step?
推荐答案
我是用双引号在Visual Studio中的pre-生成事件命令遇到了麻烦。我见过的批处理文件，解决这个问题，但它似乎是一个批处理文件，也不会解决所有问题，而不是优雅。的我找到了解决办法是关闭双引号之前放一个空格。的具体情况如下：
I was having trouble using double quotes with a pre-build event command in Visual Studio. I have seen the batch file solutions to this problem, but it seems a batch file would not solve all problems and is not elegant. I found the solution was to put a space before the closing double quote. The details are as follows.
下面的命令工作，但不会支持在路径中有空格：
The following command worked, but would not support spaces in the path:
subwcrev $（SolutionDir）$（SolutionDir）subwcrev_template.txt $（SolutionDir）version.h中
我有过在其他开发商将解决方案置于无法控制的，所以我必须支持在路径中有空格。试图用引号括住路径支持位，我想出了下面的命令。它总是失败。
I have little control over where other developers will place the solution, so I had to support spaces in the path. Trying to use quotes around paths to support spaces, I came up with the following command. It always fails.
subwcrev$（SolutionDir）$（SolutionDir）subwcrev_template.txt$（SolutionDir）version.h中
几乎是偶然，我找到了解决办法，把路径的最后一个字符和双引号之间的空间。
Almost by accident, I found the solution, put a space between the last character of the path and the double quote.
subwcrev$（SolutionDir）$（SolutionDir）subwcrev_template.txt$（SolutionDir）version.h中
这工作。我在AVR Studio中6.1，它使用一个Visual Studio壳牌测试这一点。
This worked. I tested this in AVR Studio 6.1, which uses a Visual Studio Shell.
