Powershell Active Directory查询返回空字段，该字段不应为'；T

我一直在面对这个问题，它似乎没有结束，希望你能帮助我

我正在Powershell脚本中对Active Directory进行LDAP查询。直截了当这是我的代码：

$objDomain = New-Object System.DirectoryServices.DirectoryEntry("LDAP://OU=ivegotusers,DC=global,DC=foo,DC=com")

$objSearcher = New-Object System.DirectoryServices.DirectorySearcher
$objSearcher.SearchRoot = $objDomain
$objSearcher.PageSize = 1000
$objSearcher.Filter = $strFilter
$objSearcher.SearchScope = "Subtree"

#Write-Host $objSearcher

$colProplist = "name", "sn", "whenCreated", "whenChanged", "createTimeStamp", "modifyTimeStamp", "displayName", "mailNickName"
foreach ($i in $colPropList){
    $objSearcher.PropertiesToLoad.Add($i)
}

$colResults = $objSearcher.FindAll()

foreach ($objResult in $colResults){
    $objItem = $objResult.Properties;
    Write-Host -NoNewLine $objItem.name
    Write-Host -NoNewLine "|";
    Write-Host -NoNewLine $objItem.displayName;
    Write-Host -NoNewLine "|";
    Write-Host -NoNewLine $objItem.sn;
    Write-Host -NoNewLine "|";
    Write-Host -NoNewLine $objItem.whenCreated;
    Write-Host -NoNewLine "|";
    Write-Host -NoNewLine $objItem.createTimeStamp;
    Write-Host -NoNewLine "|";
    Write-Host -NoNewLine $objItem.whenChanged;
    Write-Host -NoNewLine "|";
    Write-Host -NoNewLine $objItem.modifyTimeStamp;
    Write-Host "|";
}

因此，我们应该为每个查询匹配获取一行作为输出，行格式如下： 名称|显示名称|序号|何时创建|创建时间戳|何时更改|修改时间戳 对吧?

我检查了ADSI编辑中的数据，很多用户都有这些数据；尽管如此，产出还是

name1||sn1||||
name2||sn2||||
name3||sn3||||
name4||sn4||||
name5||sn5||||

对于相同的用户，没有一行设置了超过这两个字段。

有人能帮我弄清楚这里发生了什么吗

注意：由于服务器设置，我无法在Powershell上使用ActiveDirectory导入

谢谢你抽出时间来！

我刚才被这个咬了一口：你有两个选择：

小写的PropertyName：

foreach ($objResult in $colResults){
    $objItem = $objResult.Properties;
    Write-Host -NoNewLine $objItem.name
    Write-Host -NoNewLine "|";
    Write-Host -NoNewLine $objItem.displayname
    Write-Host -NoNewLine "|";
    Write-Host -NoNewLine $objItem.sn;
    Write-Host -NoNewLine "|";
    Write-Host -NoNewLine $objItem.whencreated;
    Write-Host -NoNewLine "|";
    Write-Host -NoNewLine $objItem.createtimestamp;
    Write-Host -NoNewLine "|";
    Write-Host -NoNewLine $objItem.whenchanged;
    Write-Host -NoNewLine "|";
    Write-Host -NoNewLine $objItem.modifytimestamp;
    Write-Host "|";
}

或使用.NET集合项属性样式语法：

foreach ($objResult in $colResults){
    $objItem = $objResult.Properties;
    Write-Host -NoNewLine $objItem.name
    Write-Host -NoNewLine "|";
    Write-Host -NoNewLine $objItem["displayName"]
    Write-Host -NoNewLine "|";
    Write-Host -NoNewLine $objItem.sn;
    Write-Host -NoNewLine "|";
    Write-Host -NoNewLine $objItem["whenCreated"];
    Write-Host -NoNewLine "|";
    Write-Host -NoNewLine $objItem["createTimeStamp"];
    Write-Host -NoNewLine "|";
    Write-Host -NoNewLine $objItem["whenChanged"];
    Write-Host -NoNewLine "|";
    Write-Host -NoNewLine $objItem["modifyTimeStamp"];
    Write-Host "|";
}

真不敢相信它起作用了！只有所有小写的属性名起了作用。当然，我现在想知道我是怎么做到不在自己之前尝试这个的。非常感谢你！真不敢相信它起作用了！只有所有小写的属性名起了作用。当然，我现在想知道我是怎么做到不在自己之前尝试这个的。非常感谢你！
