如何在 PowerShell 中连接字符串和变量? [英] How do I concatenate strings and variables in PowerShell?

问题描述

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.

您应该如何使用 PowerShell 解决这个问题?

推荐答案

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

请参阅 Windows PowerShell 语言规范版本 3.0，p34，子表达式扩展.

See the Windows PowerShell Language Specification Version 3.0, p34, sub-expressions expansion.
