Is there a .NET or Win32 version of regsvr32?

Is there a .NET or Win32 version of regsvr32? I would like to register a COM DLL with code instead of shelling out to the regsvr32 开发者_Python百科program.

The standard way of registering an assembly is to call the exported DllRegisterServer function on the assembly.

In simplified terms regsvr32 essentially does the following (error checking omitted for brevity).

HANDLE lib = LoadLibrary(...);
FARPROC proc = GetProcAddress(lib, "DllRegisterServer");
proc();

Yes, it simply requires calling the exported function. The devil is in the details though. The DLL will load all its implicitly linked dependent DLLs as well. And their DllMain() entrypoints will run. That's kinda okay in a simple process like regsvr32, not so okay in yours that needs to survive beyond the registration step.

Then there's getting the permissions to write to the registry. UAC will definitely put a stop to that, both for running Regsvr32 as well as calling the entrypoint directly. To get permission from the user you will need a separate EXE with a manifest that asks for admin rights. You're not ahead.

Look into reg-free COM, supplying the registration info in a manifest. You then won't have to register the DLL anymore. You'll get lots of hits if you search for the term.

I believe you just load the DLL, then call it exported DllRegisterServer() function.
