在C＃中获取OU的组策略属性

Question

我正在尝试在c＃中重新创建以下powershell代码。这会让我回头

Get-ADOrganizationalUnit -Filter *| Get-GPInheritance | Where-Object {$_.GPOInheritanceBlocked}

我能提出的最接近的事情（并且它不起作用）是这样的：

using Microsoft.GroupPolicy.Commands;  
using System.Management.Automation;

GetGPInheritanceCommand inheritance = new GetGPInheritanceCommand();
inheritance.Domain = domain;
inheritance.Target = "ou=brandon,dc=centoso,dc=com";
// I can't figure out where to go from here. I have tried the following:

// The below returns "d__0"
var res = inheritance.Invoke();
Console.WriteLine(res);

// The below attempt just throws an error.
foreach (var res in inheritance.Invoke())
{
     Console.WriteLine(res);
}

在涉及C＃时，MSDN对于Active Directory的组策略非常模糊。
