PSCustomObject在ISE中有效，但在powershell.exe中无效

Question

Powershell的新功能。 我正在使用用户信息创建自定义对象的列表，然后遍历此列表并将用户添加到AD。 我的脚本在ISE中运行良好，但是我想将其设置为Windows中的计划任务。 这样做时，我发现在powershell.exe中直接调用它不起作用。 重要的位：

    $usersToAdd = New-Object System.Collections.Generic.List[System.Object]

    foreach($obj in $listofobjs)
    {            $user = [PSCustomObject]@{
                'param1' = "username"
                'param2' = "group"
               }
                 $usersToAdd.Add($user)
     } 
        ForEach($user in $usersToAdd)
        {
            Add-ADGroupMember -Identity $user.param1 -Members $user.param2 -ErrorAction Stop
        }

在命令行中，添加cmdlet失败，因为参数为null。 回显$ user变量给我：

@{param1=stuff; param2=stuff2}

在ISE中，它给出了：

param1 : stuff
param2    : stuff2

编辑：全文回显然后在命令行$ user | 获得会员：

因此，就像外壳无法识别PSCustomObject一样。 我确实修改了脚本以使用Hashtables，并且工作正常。 但是两个参数上都有重复的键，因此我需要一个自定义对象。 是否需要为PSCustomObject导入模块？

Answer 1

由于我们真的不知道$listofobjs来自什么数据， $listofobjs这是我能提供的最好的数据。 如果您使用示例数据更新您的问题，我可以对其进行修改以适合您的情况。

$usersToAdd = @(foreach($obj in $listofobjs)
    {           
        New-Object psobject -property @{
            username = # property from obj related to username
            group = # property from obj related to group
       }
    })
ForEach($user in $usersToAdd)
{
    Add-ADGroupMember -Identity $user.username -Members $user.group -ErrorAction Stop
}

这是做什么的 ：

$usersToAdd只是一个简单的$usersToAdd数组，它将包含您的用户对象。 这样做是一种性能度量，因为它将遍历所有对象并创建psobject，然后将刚创建的对象数组返回到数组$usersToAdd而不是单独添加每个对象。 这是一个节省大量对象的省时方法，否则它可以按照您的方式工作。

New-Object psobject命令创建一个新的powershell自定义对象，您可以在其中创建属性的名称（在左侧）和分配给它们的值（在右侧）
