Question

我无法从作为数组一部分的对象中列出每个元素的键和值。

从代码中可以看到，我已经将对象添加到数组中，但是我只是无法获得所需的$ finalList。

$date = Get-Date
$userInfo = Get-WmiObject -Class Win32_UserAccount -Filter "LocalAccount='True'"

$userAccount = New-Object System.Collections.ArrayList
foreach ($user in $userInfo) {
    $userAccount += (@{
        "Name"=$user.Name;
        "Status"=$user.Status;
        "Disabled"=$user.Disabled;
        "AccountType"=$user.AccountType;
        "Lockout"=$user.Lockout;
        "PasswordRequired"=$user.PasswordRequired;
        "PasswordChangeable"=$user.PasswordChangeable;
        "SID"=$user.SID;
    })
}

foreach ($item in $userAccount) {
    $temp = New-Object System.Object
    $temp | Add-Member -MemberType NoteProperty -Name "Date" -Value "$date"
    $temp | Add-Member -MemberType NoteProperty -Name "Hostname" -Value "$env:computername"
    $temp | Add-Member -MemberType NoteProperty -Name "Key" -Value "$($item.Keys)"
    $temp | Add-Member -MemberType NoteProperty -Name "Value" -Value "$($item.Values)"
    $finalList.Add($temp) | Out-Null
}

使用$ finalList，我希望有一列日期，主机名和另外两列，其中包含$ userAccount数组中的键和值。 $ finalList将导出到csv。

这对我有用。从您没有声明第二个arraylist的事实来看，您的代码似乎可以正常工作。

$date = Get-Date
$userInfo = Get-WmiObject -Class Win32_UserAccount -Filter "LocalAccount='True'"

$userAccount = New-Object System.Collections.ArrayList
foreach ($user in $userInfo) {
    $userAccount += (@{
        "Name"=$user.Name;
        "Status"=$user.Status;
        "Disabled"=$user.Disabled;
        "AccountType"=$user.AccountType;
        "Lockout"=$user.Lockout;
        "PasswordRequired"=$user.PasswordRequired;
        "PasswordChangeable"=$user.PasswordChangeable;
        "SID"=$user.SID;
    })
}


$finalList = New-Object System.Collections.ArrayList
foreach ($item in $userAccount) {
    $temp = New-Object System.Object
    $temp | Add-Member -MemberType NoteProperty -Name "Date" -Value "$date"
    $temp | Add-Member -MemberType NoteProperty -Name "Hostname" -Value "$env:computername"
    $temp | Add-Member -MemberType NoteProperty -Name "Key" -Value "$($item.Keys)"
    $temp | Add-Member -MemberType NoteProperty -Name "Value" -Value "$($item.Values)"
    $finalList.Add($temp) | Out-Null
}


$finalList | Export-Csv 'C:\path\to\file.csv' -NoTypeInformation

PowerShell会自动将$ finalList设置为数组列表，但最好声明它，因为由于某些原因，即使$ finalList.GetType（）会产生相同的结果，它也不会有相同的表现。枚举哈希表$ item将使我能够根据需要获取键/值对。

$finalList = New-Object System.Collections.ArrayList
foreach ($item in $userAccount) {
    $item.GetEnumerator() | ForEach-Object {
        $temp = New-Object System.Object
        $temp | Add-Member -MemberType NoteProperty -Name "Date" -Value "$date"
        $temp | Add-Member -MemberType NoteProperty -Name "Hostname" -Value "$env:computername"
        $temp | Add-Member -MemberType NoteProperty -Name "Key" -Value $_.Key
        $temp | Add-Member -MemberType NoteProperty -Name "Value" -Value $_.Value
        $finalList.Add($temp) | Out-Null
    }
}

$finalList

尝试使用PowerShell从数组的对象部分访问每个元素
