C# API to parse ntuser.dat registry file

Is there any API for C# (or C++) which allows for parsing ntuser.dat file which does not belong to a logged user (so that I cannot use regular regis开发者_C百科try API)?

No. Just load the hive and access it normally. You can use the RegLoadKey P/Invoke. C# has no native equivalent for this but since you're talking about the registry I don't think the P/Invoke will cause platform issues for you.
