Powershell获取列出的值

我试图从哈希表中获取值，但我遇到了一些困难

$allMediafiles

是一个哈希表

这是我的代码：

$AllDoc =  ($allMediaFiles | Group-Object "video_audio" | ? {$_.name -eq 'document'}).Group

$obj2 = [pscustomobject]@{
    'FileTypes' = ($AllDoc.video_audio | Group ).Name; 
    'Format' = ($AllDoc.Format | Group).Values ;
    'O_OpenAccess' = ($AllDoc | Group-Object "SecurityTag" | ? {$_.Name -eq "O_OpenAccess"}).count; 
    'U_UserAccess' = ($AllDoc | Group-Object "SecurityTag" | ? {$_.Name -eq "U_UserAccess"}).count; 
    'S_SubscriberAccess' = ($AllDoc | Group-Object "SecurityTag" | ? {$_.Name -eq "S_SubscriberAccess"}).count;
    'REVIEW_ELDP' = ($AllDoc | Group-Object "SecurityTag" | ? {$_.Name -eq "REVIEW_ELDP"}).count;
}

我的结果是：

FileTypes Format           O_OpenAccess U_UserAccess S_SubscriberAccess REVIEW_ELDP
--------- ------           ------------ ------------ ------------------ -----------
document  {eaf, pfsx, pdf}            0           17                  2           0

我需要这样的东西：

FileTypes Format           O_OpenAccess U_UserAccess S_SubscriberAccess REVIEW_ELDP
--------- ------           ------------ ------------ ------------------ -----------
document  eaf                        0           14                  1           0
          pfsx                       0            3                  0           0
          pdf                        0            0                  1           0

谢谢你的帮助

$Alldoc =

video_audio SecurityTag        Duration Format
----------- -----------        -------- ------
document    U_UserAccess                eaf

document    U_UserAccess                pfsx  
document    U_UserAccess                pfsx  
document    U_UserAccess                eaf   
document    S_SubscriberAccess          pdf   
document    U_UserAccess                eaf

您只需再次调用

Group Object

-按

格式对记录进行分组

-然后循环结果：

foreach($format in $Alldoc |Group-Object -Property Format)
{
    [pscustomobject]@{
        # Just grab the first one - they're all identical
        'FileTypes' = $format.Group[0].video_audio
        # Grab the format Name from when we grouped them
        'Format' = $format.Name
        # For the remaining ones, simply count the number of occurences
        'O_OpenAccess' = @($format.Group |? {$_.SecurityTag -eq "O_OpenAccess"}).Count
        'U_UserAccess' = @($format.Group |? {$_.SecurityTag -eq "U_UserAccess"}).Count 
        'S_SubscriberAccess' = @($format.Group |? {$_.SecurityTag -eq "S_SubscriberAccess"}).Count
        'REVIEW_ELDP' = @($format.Group |? {$_.SecurityTag -eq "REVIEW_ELDP"}).Count
    }
}

能否将

$AllDoc

的值添加到问题正文中？是的，没问题！对不起，我的错，@AndrewAre你确定

$AllDoc

是一个哈希表，而不是（看起来）PSObject数组吗？@Theo，对不起，你说得对。$AllDoc变量是PSObject数组，是哈希表$allMediaFiles的结果$AllDoc=（$allMediaFiles |组对象“video_audio”|？{$_.name-eq'document'）。组
