Windows更新应用程序

Question

我在这里写了一个使用WUA COM接口（IUpdateSearcher,IUpdate等）的应用程序。我使用此应用程序来扫描可用更新，下载更新并安装它们。一切正常，直到我下载并安装一些更新有一些用户界面更新对话框。

当我使用IUpdateSearcher.Search()我得到这个更新，我可以成功地下载它（使用IUpdateDownloader.Download()），但是当我安装使用IUpdateInstaller2.Install()此更新我无法摆脱的用户界面。

我的问题是 - 我怎样才能使这个沉默的安装？

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


     } 

    } 
} 

Answer 2

jvelez有一个很好的答案，但它不直接回答实际问题：“我怎么能使这个沉默安装？”

CONFI - 我建议首先最简单的方法：

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(); 
} 
} 

确保所有的方法对在后台通过简单地隐藏你的UI的工作，这将让你做这无声的手段。

@Justin Choponis - 我有需要做同样的confi。 WSUS并非为我的许多客户削减它。它的实用和庞大。如果你有一个网络需要照顾，并且一直都在现场，那么WSUS会非常有用，除此之外，我觉得它非常令人不满意。
