Question

我得到的数字无效。数字常量是十进制（17），十六进制（0x11）或八进制（021）。它也一直在重命名20161201_2012312016即使我现在正在运行它应该是20160801_20160831。我已粘贴代码。感谢

@echo off

set FirstDay=01

set /a Month=%date:~4,2%-1
set Month=0%Month%
set Month=%Month:~-2%

set Year=%date:~10,4%

if %Month%==00 (
  set Month=12
  set /a Year=%Year%-1
)

if %Month%==01 set "LastDay=31" & goto foundate
if %Month%==02 set "LastDay=28" & goto foundate
if %Month%==03 set "LastDay=31" & goto foundate
if %Month%==04 set "LastDay=30" & goto foundate
if %Month%==05 set "LastDay=31" & goto foundate
if %Month%==06 set "LastDay=30" & goto foundate
if %Month%==07 set "LastDay=31" & goto foundate
if %Month%==08 set "LastDay=31" & goto foundate
if %Month%==09 set "LastDay=30" & goto foundate
if %Month%==10 set "LastDay=31" & goto foundate
if %Month%==11 set "LastDay=30" & goto foundate
if %Month%==12 set "LastDay=31" & goto foundate



:foundate
echo The year is: %Year%
echo The month is: %Month%
echo First day of this month is: %FirstDay%
echo Last day of this month is: %LastDay%

问题在于前导零，一旦你尝试执行计算就会被解释：

set month=08
set /A month+=1

将给出您报告的确切错误，因为08被解释为八进制数，并且无效，因为8不能是八进制数字。

可以通过多种方式修复。我个人的：

set month=%month:08=8%
set month=%month:09=9%
set /A month+=1
set month=%month:8=08%
set month=%month:9=09%

.bat文件无法正常工作，希望保持领先零
