Batch file 批处理：通过一个变量的值访问另一个变量,batch-file,variables,scope,Batch File,Variables,Scope,如果标题令人困惑，我深表歉意。以下是我的批处理脚本： set var=1 set ss=var rem // ss is mean to be string call :func %ss% goto :eof :func rem // I want to access to value 1 by using %1, which is ss 有什么办法吗？如果您能提供帮助，我将不胜感激。您可以使用延迟扩展 @echo off SETLOCAL ENABLEDELAYEDEXPANSIO

如果标题令人困惑，我深表歉意。以下是我的批处理脚本：

set var=1
set ss=var rem // ss is mean to be string
call :func %ss%
goto :eof

:func
    rem // I want to access to value 1 by using %1, which is ss
有什么办法吗？如果您能提供帮助，我将不胜感激。您可以使用延迟扩展

@echo off
SETLOCAL ENABLEDELAYEDEXPANSION
set var=1
set ss=var rem // ss is mean to be string
call :func %ss%
goto :eof

:func
    REM I want to access to value 1 by using %1, which is ss
    set a=%1
    REM will output '1'
    echo !%a%!
评估：
！%a%！=>！var！=>1

echo！%1!无需将参数分配给环境变量。您只需要
！%1!
