C# implementation of deep/recursive object comparison in .net 3.5

Question

I am looking for a C# specific , open source (or source code available) implementation of recursive, or deep, object comparison.

I currently have two graphs of live

This is actually a simple process. Using reflection you can compare each field on the object.

public static Boolean ObjectMatches(Object x, Object y)
{
    if (x == null && y == null)
        return true;
    else if ((x == null && y != null) || (x != null && y == null))
        return false;       

    Type tx = x.GetType();
    Type ty = y.GetType();

    if (tx != ty)
        return false;

    foreach(FieldInfo field in tx.GetFields(BindingFlags.NonPublic | BindingFlags.Public | BindingFlags.Instance | BindingFlags.DeclaredOnly))
    {
        if (field.FieldType.IsValueType && (field.GetValue(x).ToString() != field.GetValue(y).ToString()))
            return false;
        else if (field.FieldType.IsClass && !ObjectMatches(field.GetValue(x), field.GetValue(y)))
            return false;               
    }

    return true;
}
