vb.net 预生成事件获取SVN版本号，编译日期，版本日期

1、复制My Project文件夹下面的AssemblyInfo.vb文件，命名为ver.tmp.vb。

       在这个文件中，你能找到如下两行代码：

   <assembly: AssemblyVersion( "1.0.0.0" )> 
   <assembly: AssemblyFileVersion( "1.0.0.0" )>

     其中的“1.0.0.0”就是程序的版本号，它使用的是“主版本号.次版本号.内部版本号.修订号”的形式。前三个改成你自己需要的数字，最后一个改成“$WCREV$”，改完之后应该是类        似下面的样子：

   <assembly: AssemblyVersion( "1.0.0.$WCREV$" )> 
   <assembly: AssemblyFileVersion( "1.0.0.$WCREV$" )>

     <Assembly: AssemblyDescription("$WCDATE$-$WCNOW$")> ‘增加，变量代表值，可以在第四步看到

2、打开--项目--属性---编译--生成事件

3、加入命令 SubWCRev.exe $(SolutionDir) "$(ProjectDir)My Project\ver.tmp.vb" "$(ProjectDir)My Project\AssemblyInfo.vb"

       注：文件名含有空格，需要添加引号

4、可以在命令行中输入SubWCRev.exe，可以得到帮助

如下：
C:\Documents and Settings\Administrator>SubWCRev.exe
SubWCRev 1.6.5, Build 16974 - 32 Bit

Usage: SubWCRev WorkingCopyPath [SrcVersionFile DstVersionFile] [-nmdf]

Params:
WorkingCopyPath    :   path to a Subversion working copy.
SrcVersionFile     :   path to a template file containing keywords.
DstVersionFile     :   path to save the resulting parsed file.
-n                 :   if given, then SubWCRev will error if the working
                       copy contains local modifications.
-m                 :   if given, then SubWCRev will error if the working
                       copy contains mixed revisions.
-d                 :   if given, then SubWCRev will only do its job if
                       DstVersionFile does not exist.


-f                 :   if given, then SubWCRev will include the
                       last-committed revision of folders. Default is
                       to use only files to get the revision numbers.
                       this only affects $WCREV$ and $WCDATE$.
-e                 :   if given, also include dirs which are included
                       with svn:externals, but only if they're from the
                       same repository.


-x                 :   if given, then SubWCRev will write the revisions
                       numbers in HEX instead of decimal
-X                 :   if given, then SubWCRev will write the revisions
                       numbers in HEX with '0x' before them


Switches must be given in a single argument, e.g. '-nm' not '-n -m'.

SubWCRev reads the Subversion status of all files in a working copy
excluding externals. If SrcVersionFile is specified, it is scanned
for special placeholders of the form "$WCxxx$".
SrcVersionFile is then copied to DstVersionFile but the placeholders
are replaced with information about the working copy as follows:

$WCREV$         Highest committed revision number
$WCDATE$        Date of highest committed revision
$WCDATE=$       Like $WCDATE$ with an added strftime format after the =
$WCRANGE$       Update revision range
$WCURL$         Repository URL of the working copy
$WCNOW$         Current system date & time
$WCNOW=$        Like $WCNOW$ with an added strftime format after the =
$WCLOCKDATE$    Lock date for this item
$WCLOCKDATE=$   Like $WCLOCKDATE$ with an added strftime format after the =
$WCLOCKOWNER$   Lock owner for this item
$WCLOCKCOMMENT$ Lock comment for this item

The strftime format strings for $WCxxx=$ must not be longer than 1024
characters, and must not produce output greater than 1024 characters.

Placeholders of the form "$WCxxx?TrueText:FalseText$" are replaced with
TrueText if the tested condition is true, and FalseText if false.

$WCMODS$        True if local modifications found
$WCMIXED$       True if mixed update revisions found
$WCINSVN$       True if the item is versioned
$WCNEEDSLOCK$   True if the svn:needs-lock property is set
$WCISLOCKED$    True if the item is locked
