GenericDictionaryXmlSerialization.GenericDictionaryXmlSerializer 클래스 코드입니다.
앞의 예제에서는 Deserialize mthod를 Deserialize(XmlReader reader, Dictionary<TKey, TValue> dictionary) 형태로 해서 Dictionary<TKey, TValue>를 파라미터로 받고 있습니다.
이런 형식은 XmlSerializer.Deserialize method와는 다른 형식이죠.
아래의 클래스는 XmlSerializer.Deserialize method와 비슷한 형식입니다.
즉 파라미터로는 XmlReader만 받고 있습니다.
그리고 Dictionary<TKey, TValue> 을 반환하고 있습니다.
