如何将多个值从Powershell脚本返回到正在调用它的批处理文件？

我有一个Powershell脚本，它返回多个值。我想从批处理文件中调用它，并将每个单独的值放入批处理文件中的单个变量中。

只能够返回一个值

Powershell代码(pstest.ps1):

 $p1=11
 $p2=22
 $p3=33
 exit

批处理文件:

 powershell .\pstest.ps1
 :: now I'd like to get those 3 returned values 
 :: into 3 individual variables so that I can do something like this:
 @echo First is %p1%, Second is %p2%, Third is %p3%

因此，它应该显示以下内容:

 First is 11, Second is 22, Third is 33

以完全相同的方式，您可以从任何应用程序中获得多个值:每行一个...

@echo off
setlocal EnableDelayedExpansion

set "i=0"
for /F "delims=" %%a in ('powershell "$p1=11; $p2=22; $p3=33; $p1; $p2; $p3"') do (
   set /A i+=1
   set "p!i!=%%a"
)

echo First is %p1%, Second is %p2%, Third is %p3%
