批处理文件 - 纠错码失败

Question

我尝试将错误更正添加到批处理文件中。我正在尝试以下方法：

set "building="
set LANbuilding[1]=20
set LANbuilding[2]=21
set LANbuilding[3]=22
set LANbuilding[4]=23
set LANbuilding[5]=24
set LANbuilding[6]=25

:start 

set /p building="Enter the building:> "

for /l %%n in (1,1,6) do ( if %building% neq !LANbuilding[%%n]! 
echo invalid building, try again. 

goto :start ) 

else

＆＃34; else＆＃34;将继续其余的代码。

到目前为止，这不会产生任何错误，只是关闭窗口。

有什么想法吗？

Answer 1

当您期望从已知值列表中进行选择时，请不要使用Set/P。

Choice /C 123456 /N /M "Enter the building: "
Set "building=%ERRORLEVEL%"

修改

您甚至可以将其扩展为执行其他操作，例如将变量和值附加到选择中：

@Echo Off

Set "LANbuilding[1]=20"
Set "LANbuilding[2]=21"
Set "LANbuilding[3]=22"
Set "LANbuilding[4]=23"
Set "LANbuilding[5]=24"
Set "LANbuilding[6]=25"

Choice /C 123456 /N /M "Enter the building: "
Call Echo %%%%LANbuilding[%%ERRORLEVEL%%]%%%%=%%LANbuilding[%ERRORLEVEL%]%%
Timeout 5 /NoBreak>Nul

<强> EDIT2

如果您已经在使用延迟扩展，那么您应该能够直接回显这样的值：

Set "LANbuilding[1]=20"
Set "LANbuilding[2]=21"
Set "LANbuilding[3]=22"
Set "LANbuilding[4]=23"
Set "LANbuilding[5]=24"
Set "LANbuilding[6]=25"

Choice /C 123456 /N /M "Enter the building: "
Echo the value associated with LANbuilding[%ERRORLEVEL%] is !LANbuilding[%ERRORLEVEL%]!
Timeout 5 /NoBreak>Nul

<强> EDIT3

这使用Set/P和For循环，应该允许最终用户仅选择建筑物，20-25：

Set "LANbuilding[1]=20"
Set "LANbuilding[2]=21"
Set "LANbuilding[3]=22"
Set "LANbuilding[4]=23"
Set "LANbuilding[5]=24"
Set "LANbuilding[6]=25"

:Start 
Set/P "building=Enter the building: "
Set "_="
For /F "Tokens=1* Delims==" %%A In ('Set LANbuilding[ 2^>Nul'
) Do If "%building%" Equ "%%B" Set "_=%%A"
If Not Defined _ Echo invalid building, try again.&GoTo Start
Rem rest of code here:
Echo=[%%building%%=%building%]
Timeout 5 /NoBreak>Nul

在代码中，我还将变量%_%设置为LANBuilding [Number]，其值也匹配%building%！
