In the default state

ie

somemethod(Byte [] array);

is the byte array passed by method or by reference ? or do you have to
use the ref keyword to be able to mod the contents of the orig array
from inside the method ?

thanks

peted

I think u have to use ref keyword.

Without using "ref", if you modify array[i] inside somemethod, the
corresponding position is modified in the original array. If you use a "ref"
keyword, then you would be passing "a reference to the reference", which
would allow you to point the received reference somewhere else (moving the
array to a different array), besides allowing you to merely modify the
contents.

The *reference* to the byte array is passed by value.

You can change the *contents* of the array just by passing the
reference by value.
If you want the method to be able to change it to a completely
different array (e.g. a different size) you'll need to pass the
parameter by reference.
