arrays - 不能将成员添加为同名成员存在

Question

有人可以帮我获取磁盘信息吗？我有 3 个磁盘，但我无法使用 add member 获取它们的信息。

我收到一个错误:

"Add-Member : Cannot add a member with the name "Disks" because a member with that name already exists. If you want to overwrite the member anyway, use the Force parameter to overwrite it."

这是我的代码:

function  Get-Inven {

param([string[]]$computername)

#Import-Module ActiveDirectory

foreach ($computer in $computername) {
    $disks = Get-WmiObject -Class Win32_LogicalDisk -ComputerName $computer -Filter 'DriveType=3'
    $os = Get-WmiObject -Class Win32_OperatingSystem -ComputerName $computer
    #$comp = Get-ADComputer -Filter { cn=$computer }

    $info = @{
        'ComputerName'=$computer;
        'OSVersion'=$os.caption;
        'DnsHostName'=$comp.dnshostname
    }

    $obj = New-Object -TypeName PSObject -Property $info

    foreach ($disk in $disks) {
        $info = @{
            'DriveLetter'=$disk.deviceID;
            'FreeSpace'=($disk.freespace / 1MB -as [int])
        }
        $diskobj = New-Object -TypeName PSObject -Property $Info
        $obj | Add-Member -MemberType NoteProperty -Name Disks -Value $diskobj
    }
}

}

如果添加 -Force 参数，您仍然可以设置 Name 属性。您还应该添加 -PassThru 开关参数以将对象发送回管道:

$obj | Add-Member -MemberType NoteProperty -Name Disks -Value $diskobj -Force -PassThru

更新:

在我看来，您可以简化函数(没有添加成员调用):

foreach ($computer in $computername) {
    $disks = Get-WmiObject -Class Win32_LogicalDisk -ComputerName $computer -Filter 'DriveType=3'
    $os = Get-WmiObject -Class Win32_OperatingSystem -ComputerName $computer
    #$comp = Get-ADComputer -Filter { cn=$computer }

    $info = @{
        ComputerName=$computer
        OSVersion=$os.caption
        DnsHostName=$comp.dnshostname
        FreeSpaceMB= ($disks | foreach { "{0},{1:N0}" -f $_.Caption,($_.freespace/1MB) }) -join ';'
    }

    New-Object -TypeName PSObject -Property $info 
}
