如何提升UAC使用.NET COM组件 [英] How to UAC elevate a COM component with .NET

问题描述

我已经找到了如何提高C语言编写的COM对象的文章 ++调用
CoCreateInstanceAsAdmin 。但我一直没能找到或做，是落实我的.NET（C＃）应用程序作为一个COM对象的组件，然后打电话到该对象执行这就需要UAC提升的任务的方式。 MSDN文档以此为管理COM对象模型。

I've found an article on how to elevate a COM object written in C++ by calling CoCreateInstanceAsAdmin. But what I have not been able to find or do, is a way to implement a component of my .NET (c#) application as a COM object and then call into that object to execute the tasks which need UAC elevation. MSDN documents this as the admin COM object model.

我知道这是可能的，很容易启动应用程序（或其他应用程序）作为管理员，在一个单独的进程来执行任务（见实例的post从丹尼尔蛾，但我所寻找的是一个方法，从相同的，联合国框架内尽一切-elevated .NET可执行文件。这样做当然会，在产卵一个新的进程的COM对象，但由于透明的编组，在.NET COM对象的调用者不宜（太多）意识到这一点。

I am aware that it is possible and quite easy to launch the application (or another app) as an administrator, to execute the tasks in a separate process (see for instance the post from Daniel Moth, but what I am looking for is a way to do everything from within the same, un-elevated .NET executable. Doing so will, of course, spawn the COM object in a new process, but thanks to transparent marshalling, the caller of the .NET COM object should not be (too much) aware of it.

任何想法，我怎么能实例化用C＃编写的COM对象，从C＃项目，通过 CoCreateInstanceAsAdmin API将是非常有益的。所以我在学习如何写在C＃中，我可以从C＃通过COM API的标高，然后调用COM对象很感兴趣。

Any ideas as to how I could instanciate a COM object written in C#, from a C# project, through the CoCreateInstanceAsAdmin API would be very helpful. So I am really interested in learning how to write a COM object in C#, which I can then invoke from C# through the COM elevation APIs.

没关系，如果高架COM对象不会在同一个进程中运行。我只是不希望有推出提升了整个应用程序;我只是想有COM对象，将执行code升高。如果我写沿线的东西：

Never mind if the elevated COM object does not run in the same process. I just don't want to have to launch the whole application elevated; I would just like to have the COM object which will execute the code be elevated. If I could write something along the lines:

// in a dedicated assembly, marked with the following attributes:
[assembly: ComVisible (true)]
[assembly: Guid ("....")]

public class ElevatedClass
{
    public void X() { /* do something */ }
}

再有我的主要应用程序只是实例化 ElevatedClass 通过 CoCreateInstanceAsAdmin 电话。但是，也许我只是在做梦。

and then have my main application just instanciate ElevatedClass through the CoCreateInstanceAsAdmin call. But maybe I am just dreaming.

看<一个href=\"http://www.microsoft.com/downloads/details.aspx?FamilyID=2cd92e43-6cda-478a-9e3b-4f831e899433&DisplayLang=en\">Windows Vista的UAC演示示例code

（您还需要 Vista的大桥样本UnsafeNativeMethods.CoGetObject法）

(You also need the Vista Bridge sample for UnsafeNativeMethods.CoGetObject method)

它给你的C＃code，显示了几种不同的方式来提升，其中包括COM对象

Which gives you C# code that shows a few different ways to elevate, including a COM object

的（未完成code样品 - 抢档以上）的

[return: MarshalAs(UnmanagedType.Interface)]
static internal object LaunchElevatedCOMObject(Guid Clsid, Guid InterfaceID)
   {
   string CLSID = Clsid.ToString("B"); // B formatting directive: returns {xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx} 
   string monikerName = "Elevation:Administrator!new:" + CLSID;

   NativeMethods.BIND_OPTS3 bo = new NativeMethods.BIND_OPTS3();
   bo.cbStruct = (uint)Marshal.SizeOf(bo);
   bo.hwnd = IntPtr.Zero;
   bo.dwClassContext = (int)NativeMethods.CLSCTX.CLSCTX_ALL;

   object retVal = UnsafeNativeMethods.CoGetObject(monikerName, ref bo, InterfaceID);

   return (retVal);
}
