xml格式为ObservationValuexsi:type="CD"症状描述
按照如下定义类:
[System.SerializableAttribute()][System.ComponentModel.DesignerCategoryAttribute("code")][System.Xml.Serialization.XmlTypeAttribute(AnonymousType = false, Namespace = "urn:hl7-org:v3")][XmlInclude(typeof(CD))]public class ObservationValue{ }public class CD : ObservationValue{}
一定要new CD();并且AnonymousType = false 这个必须为false
