管道和噴濺

宣告 splat 對於多次重複使用引數集或稍微變化很有用：

$splat = @{
   Class = "Win32_SystemEnclosure"
   Property = "Manufacturer"
   ErrorAction = "Stop"
}

Get-WmiObject -ComputerName $env:COMPUTERNAME @splat
Get-WmiObject -ComputerName "Computer2" @splat
Get-WmiObject -ComputerName "Computer3" @splat

但是，如果 splat 沒有縮排以供重用，你可能不希望宣告它。它可以用管道傳輸：

@{
   ComputerName = $env:COMPUTERNAME
   Class = "Win32_SystemEnclosure"
   Property = "Manufacturer"
   ErrorAction = "Stop"
} | % { Get-WmiObject @_ }
