批处理文件：未能回声变量中环 [英] Batch File: Fails to Echo Variable Inside Loop

问题描述

我已经跌到了谷底，我似乎无法得到这个工作！

  SETLOCAL EnableDelayedExpansion在（1,2,3）%% g执行（
集/ A C = %% G + 32
回声％C％
）暂停
 

但它说，ECHO是的，我知道这意味着它没有任何显示，但怎么会不是有什么显示？我试图改变很多事情（添加/删除例如SETLOCAL），但它不会起作用。

任何帮助是极大AP preciated！

解决方案

 在%%克（1,2,3）做（
  集/ A C = %% G + 32
  回音！c请！
）
 

在设置/？撰文指出，我们应该使用！这种情况。

I've hit rock bottom, I can't seem to get this work!

setlocal EnableDelayedExpansion

for %%g in (1,2,3) do (
set /a c=%%g+32
echo %c%
)

pause

But it says ECHO is on, I know this means that it has nothing to display, but how couldn't it have something to display? I tried changing many things (adding/removing setlocal for example) but it won't work.

Any help is GREATLY appreciated!

解决方案

for %%g in (1,2,3) do (
  set /a c=%%g+32
  echo !c!
)

In set /? written that we should use ! for this situation.
