Convert file to binary in C#

Question

I am trying to write a program that transfers a file through sound (kind of like a fax). I broke up my program into several steps:

1. convert file to binary

Answer 1

Why don't you just open the file in binary mode? this function opens the file in binary mode and returns the byte array:

private byte[] GetBinaryFile(filename)
{
     byte[] bytes;
     using (FileStream file = new FileStream(filename, FileMode.Open, FileAccess.Read))
     {
          bytes = new byte[file.Length];
          file.Read(bytes, 0, (int)file.Length);
     }
     return bytes;
}

then to convert it to bits:

byte[] bytes = GetBinaryFile("filename.bin");
BitArray bits = new BitArray(bytes);

now bits variable holds 0,1 you wanted.

or you can just do this:

private BitArray GetFileBits(filename)
{
     byte[] bytes;
     using (FileStream file = new FileStream(filename, FileMode.Open, FileAccess.Read))
     {
          bytes = new byte[file.Length];
          file.Read(bytes, 0, (int)file.Length);
     }
     return new BitArray(bytes);
}

Or even shorter code could be:

   private BitArray GetFileBits(filename)
    {
         byte[] bytes = File.ReadAllBytes(filename);
         return new BitArray(bytes);
    }
