C# 在AdminProxy类中找不到GetUpdateServer

这是我试图运行的powershell comand。但有一个例外是——

$servername='DC1'
[reflection.assembly]::LoadWithPartialName("Microsoft.UpdateServices.Administration") | Out-Null
$wsus = [Microsoft.UpdateServices.Administration.AdminProxy]::getUpdateServer($servername,$False)

当我尝试重新引用Microsoft.UpdateServices.Administration.dll并尝试使用GetUpdateServer方法时，在AdminProxy类中找不到该方法。这是代码行-

    Exception calling "GetUpdateServer" with "2" argument(s): "The type initializer for 
'Microsoft.UpdateServices.Internal.Constants' threw an exception."
At line:3 char:1
+ $wsus = [Microsoft.UpdateServices.Administration.AdminProxy]::getUpdateServer($s ...

正如用户boeprox在评论中指出的，您需要以管理员身份运行PowerShell控制台。

注意，必须安装WSUS管理控制台才能访问所需的程序集。您安装了吗？是的，我安装了Wsus管理控制台。您是否以管理员身份运行PowerShell控制台？我看到过导致此错误发生的UAC问题，当您右键单击PowerShell并选择“以管理员身份运行”时，这些问题已得到解决。。谢谢
