title: Declaring byte array for getting bytes from a file
body: <p>Basically I'm reading all the bytes from a file into a byte array using stream reader.</p>
  
  <p>The array I have declared looks like this : <code>byte[] array = new byte[256];</code></p>
  
  <p>The size of the array 256 can read the whole bytes from the file? Saying that a file has 500 bytes instead of 256?</p>
  
  <p>Or the each element from the array has the size 256 bytes?</p>
