C# hashcode for array of ints

by

Not very clever, but sufficient for most practical purposes:

EDIT: changed due to comment of Henk Holterman, thanks for that.

  int hc = array.Length;
  foreach (int val in array)
  {
      hc = unchecked(hc * 314159 + val);
  }

If you need something more sophisticated, look here.
