问题
I've got a cool piece of code taken from a VC++ project which gets complete information of the hard disk drive WITHOUT using WMI (since WMI has got its own problems) I ask those of you who are comfortable with API functions to try to convert this VB6 code into VB (or C#) .NET and help A LOT of people who are in great need of this utility class. I've spent lots of time and searched the entire net to find ways to get the actual model and serial number of HDD and eventually found this one, if only it were in .NET... Here is the code and sorry about its formatting problems, just paste it into VB6 IDE:

I found it! Here is the equivalent VB.NET code. It's not exactly the converted version of the VB6 code, but does the same thing. Enjoy!

Sorry I don't have time to convert it for you, but if nobody else comes up with the code, you could do worse than take a look at http://www.pinvoke.net. Your VB6 code has to call Windows API functions to do the work, and VB.NET code has to do the same. It will call the same API functions.
For example, here is the page for DeviceIoControl.
But if you wait long enough, somebody else might just have the code to hand :-)

Yeah, I know VB6 but the problem is with the API function declarations and the attributes required to pass those structures (types) to them. That's where I don't have the time to spend! If you have an automated VB6 to VB.NET tool and VB6 itself, please save the code as a VB6 project and do convert the code. I don't have my VB6 around.
回答5:
That's a lot of code to wade through for someone who doesn't understand the spoken language used in the comments.
I will says this: Anywhere in that code you see the Type keyword you probably want to use Structure instead, the syntax used for Properties in .Net is a little different, function calls require parentheses, and VB.Net doesn't have an 'Any' type (maybe System.IntPtr instead? not sure).
Most of the rest of the syntax in VB.Net is the same, and so you might have better luck making the fixes I've already mentioned and then addressing each error (or type of error) you get when building the resulting code individually.

You can get this data of WMI. Let me get you an example
