Reading binary files using structures

I am pretty new in this c# development but, i have to read some data from a binary file that contains at first a header and next i have some information. The header contains several variables that i have to put into a structure but i don't know how to read this binary file with this structure and then see the result... first i will try to read only this header.
Could you help? Any answer will be helpful. 10x
