It looks like you're comparing two strings. Iirc, when using .Equals(), you are comparing the reference of the strings, not the actual contents. To implement an EqualityComparer that works with strings, you would want to use the String.Compare() method.

public class EqualityComparer : IEqualityComparer
{
     public bool Equals(ValuesAandB x, ValuesAandB y)
     {
          return ((String.Compare(x.valueA,y.valueA) == 0) &&
            (String.Compare(x.valueB, y.valueB) == 0));
     }
     // gethashcode stuff here
}

I could be a little off with the code, that should get you close...
