GetHashCode override of object containing generic array

Question

I have a class that contains the following two properties:

public int Id      { get; private set; }
public T[] Values  { get; private set; }

<

Answer 1

Provided that Id and Values will never change, and Values is not null...

public override int GetHashCode()
{
  return Id ^ Values.GetHashCode();
}

Note that your class is not immutable, since anyone can modify the contents of Values because it is an array. Given that, I wouldn't try to generate a hashcode using its contents.
