使用 Read-Host 输入多行 [英] Use Read-Host to enter multiple lines

问题描述

有没有办法使用 Read-Host cmdlet 来捕获多行?

Is there a way to use the Read-Host cmdlet to capture multiple lines?

我目前的方法有点笨拙(实际上并不奏效):

My current approach is a bit awkward (and doesn't really work):

PS> Send-MailMessage -SmtpServer 'smtp.domain.xxx' -From 'First Last <[e-mail]>' -To 'First Last <[e-mail]>' -Subject 'Testing' -Body (Read-Host 'Enter text')
Enter text: line one `n line two `n line three

生成的电子邮件正文不是三行:

Resulting email body isn't three lines:

第一行`n第二行`n第三行

推荐答案

在你刚刚拥有的地方尝试这样的事情(读取主机)

Try something like this where you just have (Read-Host)

(@(While($l=(Read-Host).Trim()){$l}) -join("`n"))

您仅使用空白/空白行退出循环.

You exit the loop with a blank/white-space only line.

您可以使用 $_ 而不是真正的变量，但我发现它令人毛骨悚然"，所以我不这样做.

You can use $_ rather than a real variable but I find that "creepy" so I don't do it.
