注册C#COM对象而没有RegAsm的真实文件

| 我有一个奇怪的应用程序加载机制。我有一个Boostrapping exe文件,其中包含所有其他DLL和应用程序本身。这些文件(程序集)是从资源中提取并加载到emand上的,因为我要附加到当前AppDomain的Assemblyresolve事件。
 [STAThread]
        static void Main()
        {
            // if the command line contains extract then extract the dlls, next run will resolve assemblies from disk
            bool saveDllsToDisk = new List<string>(Environment.GetCommandLineArgs()).Contains(\"extract\");
            // if the command line contains bin then use the bin folder instead of temp to extract dlls
            bool useBinFolder = new List<string>(Environment.GetCommandLineArgs()).Contains(\"bin\");

            if (!Directory.Exists(tempFolder)) {
                Directory.CreateDirectory(tempFolder);
            }

            // the assembly resolver will get here because it will not find the dlls in the bin folder
            // we load assemblies in our specific way:
            // - if exists in our temp/bin folder load from there
            // - else load from resources
            // - if specified extract DLLs to the temp/bin folder
            AppDomain.CurrentDomain.AssemblyResolve += (sender, args2) =>
            {
                string name = new AssemblyName(args2.Name).Name;
                Debug.WriteLine(\"START LOADING \" + name);

                Assembly assembly = null;
                string folder = useBinFolder ? binFolder : Path.Combine(tempFolder, APP_NAME);
                string fileName = name.Replace(\".\",\"_\").Replace(\"#EXE#\", \"\"); // in resources we use _ instead of .
                string extension = name.Contains(\"#EXE#\") ? \"exe\" : \"dll\"; // hack for our embedded exe files
                name = name.Replace(\"#EXE#\", \"\"); // hack for our embedded exe files

                if (File.Exists(Path.Combine(folder,String.Format(\"{0}.{1}\", name, extension))))
                {
                    // load from file in app temp folder
                    assembly = Assembly.LoadFile(Path.Combine(folder, String.Format(\"{0}.{1}\", name, extension)));
                }
                else
                {
                    // extract assembly from resources
                    byte[] assemblyBytes = (byte[])resMan.GetObject(fileName, CultureInfo.InvariantCulture);
                    assembly = Assembly.Load(assemblyBytes);

                    // if selected save to file so the next run JIT will resolve from disk
                    if (saveDllsToDisk)
                    {
                        string outDll = Path.Combine(folder, String.Format(\"{0}.{1}\", name, extension));
                        using (var fs = File.Create(outDll))
                        {
                            fs.Write(assemblyBytes, 0, assemblyBytes.Length);
                        }
                    }
                }

                Debug.WriteLine(\"LOADED \" + name);
                return assembly;
            };

            splashScreen = new frmSplash();
            // as soon as splashscreen starts animating assembly preloading will be launched on this eventhandler
            splashScreen.Started += new EventHandler(splash_Started);
            // splashscreen has finished fadein we must now wait for all libraries to be preloaded and set CanContinue
            splashScreen.Finishing += new EventHandler(splash_Finishing);
            splashScreen.CanContinue = false;

            // run splashscreen while preloading of DLLs is going on
            Application.Run(splashScreen);
        }
该引导程序只有一个引用,即对主应用程序的引用,但在main方法中未对其进行引用,以避免启动时进行程序集搜索。我要做的是在启动画面动画期间强制加载程序集:
ObjectHandle instance;

                string[,] assemblies = {
                     {\"WindowsBase, Version=3.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35\",\"dummy\"}, // will go from GAC, not our resolver

                };

                for (int i = 0; i <= assemblies.GetUpperBound(0); i++)
                {
                    try
                    {
                        instance = AppDomain.CurrentDomain.CreateInstance(assemblies[i,0], assemblies[i,1]);
                    }
                    catch (Exception ex) {
                        /* must not raise errors, it will fail because we are not actually asking for a
                         *  valid type and we only need this assembly loaded right now*/
                    }
                }
现在,您看到任何文件夹中都没有实际的dll文件,但是程序集是直接从资源中加载的程序集。 我现在的问题是:如何在我的一个dll文件中注册一个delar的COM对象? RegAsm使用文件路径注册COM对象... :( 任何帮助表示赞赏!

我正在用Excel-DNA做类似的事情。您不必将COM类型反序列化到磁盘上,也不必事先注册。我要做的是定义一个实现IClassFactory的类,然后通过调用CoRegisterClassObject将其注册为特定CLSID(类型)的当前类工厂。当COM尝试创建对象时,您的类工厂将被调用,并且可以返回.NET类型的实例。 根据上下文,您可能需要即时处理ProgID / CLSID注册。 (如果您与我联系,我很乐意帮助您从Excel-DNA代码中获取正确的信息,以帮助您入门。)
我挖了一点,也许在主要可执行文件中实现了DllRegisterServer(),然后在所有嵌入式DLL中注册所有COM类型就可以了。 谁能确认? 编辑:是的,它可以完成,但是主要的可执行文件必须是内部DLL的COM代理。
