假设我有以下片段:

$assoc = New-Object PSObject -Property @{ Id = 42 Name = "Slim Shady" Owner = "Eminem" } Write-Host $assoc.Id + " - " + $assoc.Name + " - " + $assoc.Owner

我希望这段代码能够显示:

I'd expect this snippet to show:

42 - Slim Shady - Eminem

但它显示:

42 + - + Slim Shady + - + Eminem

这让我觉得 + 运算符不适合连接字符串和变量.

Which makes me think the + operator isn't appropriate for concatenating strings and variables.

推荐答案

Write-Host "$($assoc.Id) - $($assoc.Name) - $($assoc.Owner)"
