对多台服务器上的服务进行计数

我仍然是Powershell的初学者，但喜欢学习和研究它可以做的所有事情。

因此，我希望创建一个将输出到数据网格视图表的脚本。我创建了一个足够简单的表单，其中包含一个多行文本框，您可以在其中输入服务器列表，然后只需一个简单的"检查"按钮，该按钮调用我的函数来实际查询每个服务器的服务并将该信息输出到其下方的 datagridview 中。

这部分对我来说很容易创建。我的事情是，我希望它执行以下操作"：

查询每个服务器并拉取该服务器上所有服务的列表
然后在 datagridview 中，我希望它在第 1 列中显示服务名称，然后在第 2 列中显示有多少台服务器具有该服务

希望从那以后。无法真正提供任何代码，因为我不知道如何正确编写它！我认为有某种方法可以生成完整列表，然后执行循环和计数类型的事情，但不确定。

我感谢您在这方面的任何帮助。一直在谷歌搜索和疯狂阅读。要么搜索条件不正确，要么只是没有为我点击。

更新 - 在当前脚本中添加我有：

由于您已经拥有此功能的GUI部分，因此我将重点介绍您正在寻找的数据分组。进入这个，我不清楚的一件事是为什么你有if陈述是针对的，但如果需要，我们可以解决这个问题。以下内容旨在代替您的foreach循环

$services = @()
foreach($Server in $Servername){
    $Server = $Server.ToUpper()
    $services += Get-WmiObject Win32_Service -ComputerName $Server -Filter 'StartMode="Auto"' |
            Select-Object Name, Startmode, State | 
            Add-Member -MemberType NoteProperty -Value $Server -Name "Server" -PassThru
}  
$services | Group-Object Name | ForEach-Object{
    $SvcGrid.Rows.add($_.Name,$_.Count)
}

第一件事：您没有在 wmi 调用中使用 $server 变量，因此所有结果都来自您运行此消息的一台计算机。此外，我将Where移动到-Filter中，以便加快远程计算机上的处理速度。

将所有这些信息收集到一个数组中(添加计算机名称，以防以后有用(。然后，使用该使用的结果Group-Object获取您要查找的计数。将其管道传输到另一个ForEach-Object，以在您的网格中获取结果(我尚未测试过(。

旁注：如果您只想在网格中获取信息，则可以使用Out-GridView

$services | Group-Object Name | Select name,count | Out-GridView
