How to trim few bytes of a byte array?

Question

I have a long byte array. I need to eliminate the initial 16 bytes. Is there a shortcut do it?

Answer 1

This is not the most efficient thing, but will do the trick:

// using System.Linq;

long[] array = ...;

long[] newArray = array.Skip(16).ToArray();

Answer 2

Check out Array.Copy
For example:

var array = //initialization
int bytesToEliminate = 16;
int newLength = array.Length - bytesToEliminate; //you may need to check if this positive
var newArray = new byte[newLength]; 
Array.Copy(array, bytesToEliminate, newArray, 0, newLength);
