What is the question?

And?
What does it do that you didn't expect, or not do that you did?
What help do you need?

If you're asking other people to do your work for you, you've come to the wrong site. CodeProject isn't a "convert this code for me" site. If you want someone to do your work for you, I suggest Freelancer.com and get out your credit card.

I would suggest that you write some very simple test data for your funtions. Try it in your C++ code to see the results, than you can easy debug the C# where the problems are.

Another helpful tip is that you make debug output like with TRACE macro to see what is going on.

One common issue is that the byte size is double than the string length. Than you need to convert strings. Take a look at these articles about encoding and Bitconverter.
