Writing and then reading a binary- inconsistency/incorrect

Question

public void WritingABinaryBun() ///Writing
        {

  System.IO.FileStream wFile;
                wFile = new FileStream(Path.Combine(OuputsPath, "SC03Brick201.bun"), FileMode.Create);
                byte[] bytes = BitConverter.GetBytes(-1);
                if (BitConverter.IsLittleEndian) Array.Reverse(bytes);
                wFile.Write(bytes, 0, bytes.Length);

                 bytes = BitConverter.GetBytes(10);
                if (BitConverter.IsLittleEndian) Array.Reverse(bytes);
                wFile.Write(bytes, 0, bytes.Length);

                bytes = BitConverter.GetBytes(164);
                if (BitConverter.IsLittleEndian) Array.Reverse(bytes);
                wFile.Write(bytes, 0, bytes.Length);
}


 public void ReadingABinaryBun() //Reading
        {

            using (BinaryReader b = new BinaryReader(File.Open(Path.Combine(InputsPath, "SC03Brick201.bun"), FileMode.Open)))
            {

                int pos = 0;

                int length = (int)b.BaseStream.Length;
                //long length1 = (long)b.BaseStream.Length;

                while (pos < length)
                {
                    int v = b.ReadInt32();
                    //double v1 = b.ReadDouble();

                    pos += sizeof(int);



                }
            }



        }

 

Below are 2 code snippets (which are a concise form of my code) which I'm using for writing and reading a binary file.

 

As you see, I have written 3 integer values into a binary file.

 

 

But when I read the same file through the second code snippet, I see only the foirst integer value of -1 is correctly read in.

 

Can anybody please help em understand why is it so?

 

I am using C#
