Ignore inherited class when serializing object

Question

This was the solution I came up with.

        public void WriteXml(XmlWriter writer)
        {
            foreach (PropertyInfo propertyInfo in this.GetType().GetProperties())
            {
                string name = propertyInfo.Name;

                if (propertyInfo.DeclaringType != typeof(A))
                {
                    object obj = propertyInfo.GetValue(this, null);

                    if (obj != null)
                    {
                        writer.WriteStartElement(name);
                        string value = obj.ToString();
                        writer.WriteValue(value);
                        writer.WriteEndElement();
                    }
                }
            }
        }
