hashCode() method when equals() is based on multiple independent fields

Question

i have a class whose equality is based on 2 fields such that if either one is equal then the objects of this type are considered equal. how can i write a hashCode() function for

Answer 1

How about this

public override int GetHashCode()
{
    return (id.ToString() + name.ToString()).GetHashCode();
}

The function should allways return a "valid" hash...

Edit: just noticed that you use "or" not "and" :P well i doubt there is any good solution to this problem...
