Have you looked at this answer:

http://www.codeproject.com/Answers/167756/how-can-i-convert-a-colored-bitmap-image-to-graysc.aspx

There is a very good discussion there of various ways it can be done.

There is a naive method given by CDP1802 that is actually a very good place to start in undertanding what an image is and how it can be converted.

There is a more sophisticated answer by SAKyrukov that explains why the naive answer won't necessarily give you a satisfactory result.

There are two other answers that give you more efficient ways to do it.

If, after you've looked at all these answers you still need some help, then revise your question so that we can address whatever problem you are still running into.
