Extracting segments of data from a byte array

I am getting a stream of data (int32, string, char, float and so on) into an byte array.

"byte[] data = client.Receive(refIP);"

My problem is that I dont know how to exact segments form that array.
Basically take the array and say, first 4 bits go into this variable, next 8 bits into another and so on.

Hope someone has a c# solution for me.

Thanks in advanced!!
