how to read from a binary file bit by bit

Dear sir,
the following is the code(please see the code below:) which i uses to open the binary file ,but now the problem is that 2 bytes are read in simultaneously and is being converted into an integer,but i need to read the data from the file in bits and finally convert 8 bits into binary numbers and then to decimal numbers? could you be able to give me some advice ? is it ok if i read all the bytes into a an array and then try to convert it into a bit array?


with regards,
tom.


using System;
using System.IO;
using System.Collections;


class Program
{
    static void Main()
    {
        R();
    }

    static void R()
    {
        // 1.
        using (BinaryReader b = new BinaryReader(File.Open("file.bin", FileMode.Open)))
        {
            // 2.
            // Position and length variables.
            int pos = 0;
            // 2A.
            // Use BaseStream.
            int length = (int)b.BaseStream.Length;
            while (pos < length)
            {
                // 3.
                // Read integer.
                int v = b.ReadInt32();
                Console.WriteLine(v);

                // 4.
                // Advance our position variable.
                pos += sizeof(int);

                // 5.
                // Seek to our required position.(int pos1 had to be found out )
                //int pos1 = 0;
                //b.BaseStream.Seek(pos1, SeekOrigin.Begin);

                // 6.
                // Read the next 2000 bytes or required number of bytes int the byte array(int required had to be found out ).
                //int required = 20000;
                //byte[] by = b.ReadBytes(required);

                
               




                //.8 convert to bit array
                //BitArray myBits = new BitArray(by);
                byte[] value = { 0x11 };
                BitArray myBits = new BitArray(value);
            
            
            }

            Console.ReadLine();
        }
    }
}

and the following is the data which i gets when i try to open this file with visual studio:

If you have one binary files with some header, body, etc. Well you might find the following functions very handy:
You supply an object, e.g your custom structure/class.
Returns: byte array, you can simply write using BinaryWriter in a file.
public static byte[] RawSerialize( object anything )
 {
       int rawsize = Marshal.SizeOf( anything );
       IntPtr buffer = Marshal.AllocHGlobal( rawsize );
       Marshal.StructureToPtr( anything, buffer, false );
       byte[] rawdatas = new byte[ rawsize ];
       Marshal.Copy( buffer, rawdatas, 0, rawsize );
       Marshal.FreeHGlobal( buffer );
       return rawdatas;
 }
For the next one you supply the bytes read from BinaryReader as well as the type of your suctom structure to cast later to.
Returns object, representing you structure. Note: you must cast to your structure.
public static object RawDeserialize( byte[] rawdatas, Type anytype )
 {
       int rawsize = Marshal.SizeOf( anytype );
       if( rawsize > rawdatas.Length )
              return null;
       IntPtr buffer = Marshal.AllocHGlobal( rawsize );
       Marshal.Copy( rawdatas, 0, buffer, rawsize );
       object retobj = Marshal.PtrToStructure( buffer, anytype );
       Marshal.FreeHGlobal( buffer );
       return retobj;
 }
Now you might need some example how to use the functions above in real life example.
Lets first have a custo structure:
[StructLayout(LayoutKind.Sequential)]
struct SomeFileHeader
{
      [MarshalAs(UnmanagedType.ByValTStr, SizeConst = 4)]
      public string Signature;
      public Int32 Offset;
      public Int32 Length;
}
At last here is an example(you should have already binaryReader assoc to a file):
//our custom structure
SomeFileHeader someFileHeader =new SomeFileHeader();
//temp byte array buffer 
private byte[] buf =new byte[Marshal.SizeOf(SomeFileHeader ));
//Read the header from the file stream and save it to an byte array
buf = binaryReader.ReadBytes(Marshal.SizeOf(SomeFileHead  er ));
                       
//Deserialization of the byte array (buf) to out PakHeader structure
someFileHeader = (SomeFileHeader ) RawDeserialize(buf,someFileHeader .GetType());
After that you should be able to read all members from your struct.
