通過.NET使用組策略對象（GPO）\ C＃

Question

我想將註冊表項添加到GPO註冊表項？標準的.NET註冊表類不處理這種情況。

Answer 1

我發現的工作解決方案是使用組策略對象COM + API接口。

備註：

• 線程標記爲STA必須使用。它可以應用於整個應用程序或只是一個線程;

• COM + IGroupPolicyObject必須通過ComInterop使用;

• MS鼓勵在.NET中使用「GPMC類庫」，但該庫無法正常工作;

• .NET端IGroupPolicyObject代理必須包含來自COM對象的所有方法的定義（否則將引發異常「嘗試讀取或寫入受保護的內存，這通常表示其他內存已損壞。 「通過一種方法）;

下面的代碼使註冊表項的管理（添加，刪除等）GPO下：

static void Main(string[] args) 
{ 
    Thread t = new Thread(new ThreadStart(StartNewStaThread)); 
    t.SetApartmentState(ApartmentState.STA); 
    t.Start(); 
} 

private static void StartNewStaThread() 
{ 
    GPClass gpClass = new GPClass(); 
    IGroupPolicyObject gpo = (IGroupPolicyObject)gpClass; 

    uint hr = gpo.OpenLocalMachineGpo(1); // GPO_OPEN_LOAD_REGISTRY=0x00000001 

    if (hr == 0) //S_OK == 0 
    { 
     StringBuilder sb = new StringBuilder(); 
     hr = gpo.GetDisplayName(sb, 50); 
    } 
}
