如何在PowerShell中断行？(How to break lines in PowerShell?)

我是PowerShell的全新功能，并且在循环中连接一个字符串，如果发生特殊情况，我应该插入一个换行符...我该怎么做？

基本上寻找相当于\n 。

$str = ""
foreach($line in $file){
  if($line -Match $review){ #Special condition
    $str += ANSWER #looking for ANSWER
  }
  #code.....
}
 
 到目前为止我已经试过了 
 
"\n" '\n' "\N" '\N' "\r" '\r' "\R" '\R' '`n' '`r' '-n' '-r' 
I am [completely new to PowerShell and] concatenating a string in a loop, if a special condition occurs I should insert a line break...how can I do this?
 
Basically looking for the equivalent of \n.
 
$str = ""
foreach($line in $file){
  if($line -Match $review){ #Special condition
    $str += ANSWER #looking for ANSWER
  }
  #code.....
}
 
So far I have tried 
 
"\n" '\n' "\N" '\N' "\r" '\r' "\R" '\R' '`n' '`r' '-n' '-r'

 尝试`n （ 不是 '`n' ） 
 
 有关转义字符的完整列表，请参阅： 
 
 Help about_Escape_character 
 
 代码应该是 
 
$str += "`n"
Try "`n" with double quotes. (not single quotes '`n' )
 
For a complete list of escaping characters see:
 
Help about_Escape_character
 
The code should be
 
$str += "`n"
