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，包含所有其他DLL和应用程序本身的资源。 这些文件（程序集）是从资源中提取并加载的，因为我附加到当前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(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(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); } 

这个引导程序只有一个引用，即主应用程序，但它不会在main方法中引用它以避免在开始时进行程序集搜索。 我所做的是在启动画面动画期间强制assembly：

 ObjectHandle instance; string[,] assemblies = { {"WindowsBase, Version=3.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35","dummy"}, // will go from GAC, not our resolver {"PresentationCore, Version=3.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35","dummy"}, // will go from GAC, not our resolver {"PresentationFramework, Version=3.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35","dummy"}, // will go from GAC, not our resolver {"WindowsFormsIntegration, Version=3.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35","dummy"}, // will go from GAC, not our resolver {"PresentationFramework.Aero, Version=3.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35","dummy"}, // will go from GAC, not our resolver {"System.Core, Version=3.5.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089","dummy"}, // will go from GAC, not our resolver {"AvalonDock, Version=1.3.3585.0, Culture=neutral, PublicKeyToken=85a1e0ada7ec13e4", "dummy"}, // out reference inside resources {"AvalonDock.Themes, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null", "dummy"}, // out reference inside resources {"ICSharpCode.AvalonEdit, Version=4.0.0.5950, Culture=neutral, PublicKeyToken=9cc39be672370310", "dummy"}, // out reference inside resources {"WPG, Version=2.0.4120.37542, Culture=neutral, PublicKeyToken=null","dummy"}, // out reference inside resources {"WPGBrushEditor, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null","dummy"}, // out reference inside resources {"HLSLEditor, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null","dummy"} // preload even our main file that will launch after the splashscreen }; 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，但是直接从资源加载的程序集。

我现在的问题是：如何在我的一个dll文件中注册一个COM对象？

RegAsm使用文件路径注册COM对象…… 🙁

任何帮助赞赏！

Answer 1

我在Excel-DNA中做了非常相似的事情。 您不必将COM类型反序列化为磁盘，也不必提前注册它们。 我所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，将调用类工厂并返回.NET类型的实例。

根据上下文，您可能必须动态处理ProgID / CLSID注册。

（如果您与我联系，我很乐意帮助您从Excel-DNA代码中获取正确的位，以帮助您入门。）

我挖了一点，也许实现DllRegisterServer（）intot他的主要可执行文件，然后注册所有嵌入式DLL中的所有COM类型将工作…

谁能确认一下？

编辑：是的它可以完成，但主可执行文件必须是DLL内部的COM代理。
