元素「：項目」包含映射到名稱的數據類型 「http://schemas.microsoft.com/search/local/ws/rest/V1：路線「。 解串器不知道映射到此名稱的任何類型 考慮使用DataContractResolver或將'Route'對應的類型添加到已知類型的列表中 - 例如，使用 KnownTypeAttribute屬性或將它添加到已知 類型傳遞給DataContractSerializer的列表。Metro風格應用程序：JSON對象反序列化錯誤，REST服務
加入[DataContract（命名空間= 「http://schemas.microsoft.com/search/local/ws/rest/v1」，名稱後= 「位置」）] RO資源類，我得到這個異常：
期待狀態 '元素' ..遇到名稱 ''，命名空間'
