如何批量迭代数组key = value item [英] How to iterate over array in batch for key=value item

问题描述

我有一个数组定义为 LIST =（a b c d e）。 a，b，c，d，e 被设置为系统变量，例如。 a = AAA，b = BBB 等

在批处理脚本中，我想做一个for循环看起来像：

  for %% i％in％LIST％do echo %% i = %%% i％（不幸的是，这是行不通的）
  

我想达到的是 %% i（a）= %%% i％（％a％），它将被解析为系统变量，而不是显示％a％，它将被解析为 a = AAA 。

你有什么想法如何做一个批处理脚本？

谢谢！

解决方案

< code％for %% i in％LIST％do CALL echo %% i = %%%% i %%

可以解决你的问题。

I have an array defined as LIST=(a b c d e). The a, b, c, d, e are set as system variables, eg. a=AAA, b=BBB, etc.

In a batch script, I would like to do a for loop looking like:

for %%i in %LIST% do echo %%i=%%%i% (unfortunately, this doesn't work)

What I want to achieve is that %%i (a) = %%%i% (%a%), which will be resolved as system variable, thus instead of showing %a%, it'll be resolved as a=AAA.

Do you have any idea how to do it in a batch script?

Thanks!

解决方案

for %%i in %LIST% do CALL echo %%i=%%%%i%%

should solve your problem.
