无法比较批处理文件中的2个整数变量(Unable to compare 2 integer variables in batch file)

无法比较批处理文件中的2个整数变量(Unable to compare 2 integer variables in batch file)

我有以下这段代码，我基本上试图比较批处理文件中的2个整数（其中一个从注册表中检索） -

set mainCounter=1 reg add HKLM\Software\Looptest /f /v mainCounter1 /t REG_SZ /d 0 rem ---- some code here --- FOR /f "tokens=2*" %%a in ('reg query "HKLM\SOFTWARE\Looptest" /v "mainCounter1"') do set "mainCounter1=%%b" echo mainCounter :: %mainCounter% echo mainCounter1 :: %mainCounter1% if %mainCounter% EQU %mainCounter1% goto _reImageSystem :_reImageSystem echo mainCounter while reimaging :: %mainCounter% echo mainCounter1 while reimaging :: %mainCounter1% pause

这段代码清楚地表明，mainCounter的值是1（手动设置）而且，mainCounter1的值设置为registry ..这是0.但是，当我比较if %mainCounter% EQU %mainCounter1% goto _reImageSystem ，显然应该不要进入_reImageSystem，但它会......

输出是：

mainCounter :: 1 mainCounter1 :: 0 mainCounter while reimaging :: 1 mainCounter1 while reimaging :: 0

所以，可能比较不起作用..

if %mainCounter% EQU %mainCounter1% goto _reImageSystem

有什么建议么 ？

谢谢！

I have this following piece of code where I am basically trying to compare 2 integers in a batch file (one of them is retrieved from registry) -

set mainCounter=1 reg add HKLM\Software\Looptest /f /v mainCounter1 /t REG_SZ /d 0 rem ---- some code here --- FOR /f "tokens=2*" %%a in ('reg query "HKLM\SOFTWARE\Looptest" /v "mainCounter1"') do set "mainCounter1=%%b" echo mainCounter :: %mainCounter% echo mainCounter1 :: %mainCounter1% if %mainCounter% EQU %mainCounter1% goto _reImageSystem :_reImageSystem echo mainCounter while reimaging :: %mainCounter% echo mainCounter1 while reimaging :: %mainCounter1% pause

This code clearly suggests that, value of mainCounter is 1 (set manually) And, The value of mainCounter1 is set to registry.. which is 0. Still , when I compare if %mainCounter% EQU %mainCounter1% goto _reImageSystem , clearly it should not go inside _reImageSystem, but it goes...

The output is:

mainCounter :: 1 mainCounter1 :: 0 mainCounter while reimaging :: 1 mainCounter1 while reimaging :: 0

So, possible the comparison is not working..

if %mainCounter% EQU %mainCounter1% goto _reImageSystem

Any suggestions ?

Thanks!

如果比较为假，它仍将落入标签并执行。

为了防止这个分支：

if %mainCounter% EQU %mainCounter1% goto _reImageSystem goto end :_reImageSystem bla bla bla bla :end

（或GOTO:eof结束或反转你的逻辑并使用NEQ ）

If the comparison is false it will still fall through to the label and execute.

To prevent this branch away:

if %mainCounter% EQU %mainCounter1% goto _reImageSystem goto end :_reImageSystem bla bla bla bla :end

(Or GOTO:eof to end or invert your logic and use NEQ)
