Comparing object properties in c# [closed]

Answer 1

here is revised one to treat null = null as equal

 private bool PublicInstancePropertiesEqual(T self, T to, params string[] ignore) where T : class
        {
            if (self != null && to != null)
            {
                Type type = typeof(T);
                List ignoreList = new List(ignore);
                foreach (PropertyInfo pi in type.GetProperties(BindingFlags.Public | BindingFlags.Instance))
                {
                    if (!ignoreList.Contains(pi.Name))
                    {
                        object selfValue = type.GetProperty(pi.Name).GetValue(self, null);
                        object toValue = type.GetProperty(pi.Name).GetValue(to, null);
                        if (selfValue != null)
                        {
                            if (!selfValue.Equals(toValue))
                                return false;
                        }
                        else if (toValue != null)
                            return false;
                    }
                }
                return true;
            }
            return self == to;
        }
