}

使用[pscustomobject]强制类型转换

使用Select-Object

$Object = ‘‘ | Select-Object Name, Number, ID
$Object.Name = ‘Boe‘
$Object.Number = 1
$Object.ID = 007

借助Add-Member

$Object = New-Object PSObject
$Object | Add-Member -MemberType NoteProperty -Name Name -Value Boe -PassThru |
Add-Member -MemberType NoteProperty -Name Number -Value 1 -PassThru |
Add-Member -MemberType NoteProperty -Name ID -Value 007 -PassThru
