序列化常用Attribute讲解说明

[XmlRootAttribute("MyCity", Namespace="abc.abc", IsNullable=false)]     // 当该类为Xml根节点时，以此为根节点名称。

public class City

[XmlAttribute("AreaName")]    // 表现为Xml节点属性。<... AreaName="..."/>

public string Name

[XmlElementAttribute("AreaId", IsNullable = false)]    // 表现为Xml节点。<AreaId>...</AreaId>

public string Id

[XmlArrayAttribute("Areas")]    // 表现为Xml层次结构，根为Areas，其所属的每个该集合节点元素名为类名。<Areas><Area ... /><Area ... /></Areas>

public Area[] Areas

[XmlElementAttribute("Area", IsNullable = false)]    // 表现为水平结构的Xml节点。<Area ... /><Area ... />...

public Area[] Areas

[XmlIgnoreAttribute]    // 忽略该元素的序列化。
