读取多种颜色的主机

Question

在我的一个powershell函数中，我想收集用户的输入，但首先我需要给出一些说明。我想在控制台上用不同的颜色打印一两行。

function myFunction(){
param(
[string]$directions = $(read-host "Please answer the questions according to your opinion`nYour answers must be Star Wars-based." -foregroundcolor "Magenta"),
[string]$robot = $(read-host "What is your favourite robot" -foregroundcolor "Yellow"),
[string]$spaceship = $(read-host "What is your favourite spaceship" -foregroundcolor "Green")
)
write-host "Favourite Robot = " + $robot
write-host "Favourite Spaceship = " + $spaceship
}
#call the function
myFunction

在上面的函数中，我有一个换行符来保持不同级别的方向，但我希望文本的第一行是一种颜色，第二行是另一种颜色。

此外，-foregroundcolor在这里不起作用——它只是按字面打印。

我不能把write-host放在param语句之前，否则我会把方向放在那里(我知道如何用多种颜色来做这个(。

您似乎对注释中的说明有点吃力，所以在这里。。。不知道为什么你想要一个读主机来获取说明，但这很酷。

function myFunction(){
param(
[string]$directions = $(Write-Host "Please answer the questions according to your opinion`nYour answers must be Star Wars-based.: " -ForegroundColor Magenta -NoNewline; Read-Host),
[string]$robot = $(Write-Host "What is your favourite robot: " -ForegroundColor Yellow -NoNewline; Read-Host),
[string]$spaceship = $(Write-Host "What is your favourite spaceship: " -ForegroundColor Green -NoNewline; Read-Host)
)
write-host "Favourite Robot = "$robot
write-host "Favourite Spaceship = "$spaceship
}
