Question

有人可以帮助我获取磁盘信息吗？我有3个磁盘，但我无法使用添加成员获取其信息。

我收到错误：

"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
    }
}

}

Answer 1

如果添加-Force参数，仍可以设置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，你可以简化功能（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 
}

Answer 2

由于存在多个磁盘，因此需要将磁盘属性创建为阵列，然后将每个磁盘添加到阵列。另外，请记住在$obj foreach的末尾输出$computername。

function  Get-Inven {

param([string[]]$computername)
$computername = 'localhost'
foreach ($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 
    $obj | Add-Member -MemberType NoteProperty -Name Disks -Value @()
    $obj | Add-Member -MemberType ScriptProperty -Name DisksList -Value {
        ($this.Disks|%{$_.DriveLetter + ',' + $_.FreeSpace}) -join ';'
    }
    foreach ($disk in $disks) {
        $info = @{
            'DriveLetter'=$disk.deviceID;
            'FreeSpace'=($disk.freespace / 1MB -as [int])
        }
        $diskobj = New-Object -TypeName PSObject -Property $Info
        $obj.Disks += $diskobj
    }
    $obj
}
}

$result = get-inven localhost
$result| select "OSVersion","DnsHostName","ComputerName","DisksList"|ConvertTo-Csv

无法添加成员作为名称存在的成员
