Binary file is read with bytes missing

Hi, im a new programmer to C# and I just do not understand why my binary file is read incorrectly.

I have a 625 byte binary file and it only reads 586 bytes, skipping a byte once in a while.
The result is the same everytime.

Is there something im missing?

Any help would be truly appriciated.

Code:

---

        //Returns the file data as a byte array

        public static byte[] readfilebytes(string filex)
        {

            TextReader tr = new StreamReader(filex);
            string buffer;
            string collected = "";


            while ((buffer = tr.ReadLine()) != null)
            {
                collected += buffer;
            }

               
            tr.Close();
            Console.WriteLine(collected.Length);
            //625 byte binary file
            //586 bytes in the variable collected
       

            byte[] bytes = new byte[collected.Length];
            int i = 0;
            foreach (char c in collected.ToCharArray())
            {
                bytes[i] = (byte)c;
                i++;
            }

            return (bytes);

        }

One enter between the two D's is also a byte, but it is not read into the buffer, thus not copied into bytes ( your program will output 2 but filesize will be 3 bytes ) ....

None of escape characters like \0 ( end of string in C ), \n end of line , \t etc etc are not being taken into account in your program. When you check the filesize these bytes will be taken into account, thus explaining the difference :).

A suggestion: use BinaryReader , .BaseStream.Length to know the length of the stream instead of copying to a buffer first.
