我正在尝试编写一个批处理文件，该文件将通过选择一个数字来卸载程序。我不知道如何计算操作系统中有多少程序，然后以 MENU 格式为所有程序分配编号。我不想在程序中输入所有字母。

将以下程序复制并粘贴到记事本中并另存为 GUninstall.bat

@Echo off
Echo This is a batch file uninstallation program. 
Echo Run as administrator WMIC will not work. 
echo.
Echo The command [wmic product get name] will run.
Echo Looking up all installed programs...
echo. 
wmic product get name

echo 1. First program
echo 2. Second program
echo 3. Third program
echo 4. Fourth program
echo 5. Fifth program
echo.
@echo Pick a number: 
echo. 
choice /c:12345 

if "%errorlevel%"=="1" wmic product where name="First program" call uninstall
if "%errorlevel%"=="2" wmic product where name="Second program" call uninstall
if "%errorlevel%"=="3" wmic product where name="Third program" call uninstall
if "%errorlevel%"=="4" wmic product where name="Fourth program" call uninstall
if "%errorlevel%"=="5" wmic product where name="Fifth program" call uninstall

Echo.
Echo.

@echo First method is done. I'll go into the alternate method. 

pause
Echo Get user input - program name?
Echo.
Echo This is an alternate method 
:input
set INPUT=
set /P INPUT=Uninstall which program?: %=%
if "%INPUT%"=="" goto input
echo Your input was: %INPUT%

echo.
echo.
Echo Uninstalling... 

echo The command [wmic product where name="%INPUT%" call uninstall] will run. 


wmic product where name="%INPUT%" call uninstall

@echo If there is "no instance" errors, then the program %INPUT% was uninstalled.

pause

FOR- 循环是大多数问题的答案。

-loop可以FOR/F收集所有程序并对其进行计数。 

set count=0
for /F "delims=" %%A in ('wmic product get name' ) do (
  set /a count+=1
  setlocal EnableDelayedExpansion
  for %%n in (!count!) do (
    endlocal
    set product[%%n]=%%A
    echo %%n. %%A
  )
)

稍后您可以通过数组从数组中访问它们

SET /p uninstallNr=Uninstall number:
setlocal EnableDelayedExpansion
ECHO !product[%uninstallNr%]!
