大致是这样的:

获取.NET Framework目录中名称匹配的容器的子项 模式vnumber·number。按名称降序排序，取第一个对象， 并返回其name属性。

剧本如下:

(Get-ChildItem -Path $Env:windir\Microsoft.NET\Framework | Where-Object {$_.PSIsContainer -eq $true } | Where-Object {$_.Name -match 'v\d\.\d'} | Sort-Object -Property Name -Descending | Select-Object -First 1).Name

这纯粹是因为当它应该被广泛使用时，我不得不花时间制作/编辑它，所以我把它提供给其他人。

下面的脚本将输出两个CSV文件到TEMP，其中包含所选OU(代码中)中每台机器的版本和漏洞状态。您将能够远程“安全审计”计算机OU。

连接测试线路需要Powershell 7.0 RSAT需要得到AD模块 获得powershell 7.0所需的Visual Studio代码(win7上)

当您阅读本文时，文件中的版本列表可能已经过期。使用此网站https://learn.microsoft.com/en-us/dotnet/framework/migration-guide/versions-and-dependencies添加新的dotnet条目。它只是DotNet4Builds中的一堆键值

如果在compresedcheck .csv中，一台机器显示为=0，那么它已经手动关闭了安全性，您应该提出是供应商做的，还是可疑员工做的。

我希望这有助于人们搜索它为他们的业务。

我想在PowerShell中试试这个: 为我工作!

(Get-ItemProperty "HKLM:Software\Microsoft\NET Framework Setup\NDP\v4\Full")。版本

我在osx的powershell中通过制表符补全发现了这个:

[System.Runtime.InteropServices.RuntimeInformation]:: get_FrameworkDescription () .NET Core 4.6.25009.03

以下是我对这个问题的看法:

$gpParams = @{
    Path        = 'HKLM:\SOFTWARE\Microsoft\NET Framework Setup\NDP\v4\Full'
    ErrorAction = 'SilentlyContinue'
}
$release = Get-ItemProperty @gpParams | Select-Object -ExpandProperty Release

".NET Framework$(
    switch ($release) {
        ({ $_ -ge 528040 }) { ' 4.8'; break }
        ({ $_ -ge 461808 }) { ' 4.7.2'; break }
        ({ $_ -ge 461308 }) { ' 4.7.1'; break }
        ({ $_ -ge 460798 }) { ' 4.7'; break }
        ({ $_ -ge 394802 }) { ' 4.6.2'; break }
        ({ $_ -ge 394254 }) { ' 4.6.1'; break }
        ({ $_ -ge 393295 }) { ' 4.6'; break }
        ({ $_ -ge 379893 }) { ' 4.5.2'; break }
        ({ $_ -ge 378675 }) { ' 4.5.1'; break }
        ({ $_ -ge 378389 }) { ' 4.5'; break }
        default { ': 4.5+ not installed.' }
    }
)"

这个例子适用于所有PowerShell版本，并且将永远工作，因为4.8是最后一个。net Framework版本。

没有可靠的方法可以使用一个简单的脚本为所有平台和体系结构做到这一点。如果你想学习如何可靠地完成它，请从博客文章更新的。net框架检测代码样本开始，它可以进行更深入的检查。
