Question

I have a .NET application which serializes an object in binary format. this object is a struct consisting of a few fields.

I must deserialize and use this object in a C+

Do you have the option of changing the format? If so, consider choosing a non-binary format for greater interoperability. There are plenty of libraries for reading and writing XML. Json is popular as well.

Binary formats are efficient, but vulnerable to implementation details (does your C++ compiler pack data structures? how are ints and floats represented? what byte ordering is used?), and difficult to adjust if mangled. Text based formats are verbose, but tend to be much more robust. If you are uncertain about binary representations, text representations tend to be easier to understand (apart from challenges such as code pages and wide/narrow characters...).

For C++ XML libraries, the most capable (and perhaps also most complex) would still seem to be the Xerces library. But you should decide for yourself which library best fits your needs and skills.
