如何将文件内容读入批处理文件中的变量？(How to read file contents into a variable in a batch file?)

 该批处理文件将从TEST发布到LIVE。 我想在此文件中添加一个检查约束，以确保在特定文件夹中有一个附带的发行文档。 
 
"C:\Program Files\Windows Resource Kits\Tools\robocopy.exe" "\\testserver\testapp$"        
"\\liveserver\liveapp$" *.* /E /XA:H /PURGE /XO /XD ".svn" /NDL /NC /NS /NP
del "\\liveserver\liveapp$\web.config"
ren "\\liveserver\liveapp$\web.live.config" web.config
 
 所以我有几个关于如何实现这个的问题？ 
 
 
 
 \\testserver\testapp$文件夹中有一个version.txt文件，该文件的唯一内容是构建号（例如，45 - 用于构建45）如何读取version.txt文件的内容在批处理文件中变成一个变量？ 
 
 
 如何使用第1部分的变量代替{build}，检查文件\\fileserver\myapp\releasedocs\ {build}.doc存在？ 
 

This batch file releases a build from TEST to LIVE. I want to add a check constraint in this file that ensures there is an accomanying release document in a specific folder.
 
"C:\Program Files\Windows Resource Kits\Tools\robocopy.exe" "\\testserver\testapp$"        
"\\liveserver\liveapp$" *.* /E /XA:H /PURGE /XO /XD ".svn" /NDL /NC /NS /NP
del "\\liveserver\liveapp$\web.config"
ren "\\liveserver\liveapp$\web.live.config" web.config
 
So I have a couple of questions about how to achieve this...
 
 
 
There is a version.txt file in the \\testserver\testapp$ folder, and the only contents of this file is the build number (for example, 45 - for build 45) How do I read the contents of the version.txt file into a variable in the batch file?
 
 
How do I check if a file ,\\fileserver\myapp\releasedocs\ {build}.doc, exists using the variable from part 1 in place of {build}?
