PowerShell中哈希表值的字符串插值

Question

我有一个哈希表:

$hash = @{ First = 'Al'; Last = 'Bundy' }

我知道我可以这样做:

Write-Host "Computer name is ${env:COMPUTERNAME}"

所以我希望这样做:

Write-Host "Hello, ${hash.First} ${hash.Last}."

......但我得到了这个:

Hello,  .

如何在字符串插值中引用哈希表成员？

Answer 1

Write-Host "Hello, $($hash.First) $($hash.Last)."

Answer 2

"Hello, {0} {1}." -f $hash["First"] , $hash["Last"]
