Windows更新應用程序

Question

我在這裏寫了一個使用WUA COM接口（IUpdateSearcher,IUpdate等）的應用程序。我使用此應用程序來掃描可用更新，下載更新並安裝它們。一切正常，直到我下載並安裝一些更新有一些用戶界面更新對話框。

當我使用IUpdateSearcher.Search()我得到這個更新，我可以成功地下載它（使用IUpdateDownloader.Download()），但是當我安裝使用IUpdateInstaller2.Install()此更新我無法擺脫的用戶界面。

我的問題是 - 我怎樣才能使這個沉默的安裝？

       updates.EnableService(); 
       Console.WriteLine("Service enable success"); 
      } 


     } 

    }

Answer 2

jvelez有一個很好的答案，但它不直接回答實際問題：「我怎麼能使這個沉默安裝？」

CONFI - 我建議首先最簡單的方法：

static class Program 
{ 
/// <summary> 
/// The main entry point for the application. 
/// </summary> 
[STAThread] 
static void Main() 
{ 
Application.SetCompatibleTextRenderingDefault(false); 
Application.EnableVisualStyles(); 

Thread thread = new Thread(() => 
{ 
Form1 form1 = new Form1(); 
form1.Visible = false; 
form1.ShowInTaskbar = false; 
Application.Run(form1); 
}); 

thread.SetApartmentState(ApartmentState.STA); 
thread.Start(); 
} 
} 

確保所有的方法對在後臺通過簡單地隱藏你的UI的工作，這將讓你做這無聲的手段。

@Justin Choponis - 我有需要做同樣的confi。 WSUS並非爲我的許多客戶削減它。它的實用和龐大。如果你有一個網絡需要照顧，並且一直都在現場，那麼WSUS會非常有用，除此之外，我覺得它非常令人不滿意。
