C#的XML序列化和反序列化2

5.格式化文本內容        

         [XmlText()]
         public string Name
         {
             get { return name; }
             set { name = value; }
         }

         則Name會生成在<Pupil>XXX(Name)</Pupil>中作爲文本

     6.爲元素/屬性定義數據類型
         XML Schema類型與.NET數據類型有一個Mapping，比如說type對應System.DateTime

         [XmlElement(DataType = " date " )]
         public DateTime EnrollDate
         {
             get { return enrollDate; }
             set { enrollDate = value; }
         }

         於是生成XML： <EnrollDate>2007-10-19</EnrollDate>
         XMLRoot，XmlAttribute，XMLElement，XMLText，XMLArrayItem標籤都可以指定DataType

     7.爲枚舉修飾符指定其他名稱

         public enum Color
         {
             [XmlEnum(Name = " White Color " )]
             White,
             [XmlEnum(Name = " Black Color " )]
             Black,
             [XmlEnum(Name = " Red Color " )]
             Red
         }

         private Color showColor;

         public Color ShowColor
         {
             get { return showColor; }
             set { showColor = value; }
         }

生成XML如下格式：
     <ShowColor>White Color</ShowColor>

     8.串行化多肽數組

         [XmlArray(ElementName = " Cources " ),
         XmlArrayItem(Type = typeof (String), ElementName = " CourceName " ),
         XmlArrayItem(Type = typeof (Int32), ElementName = " CourceCode " )]
         public Object[] Subjects
         {
             get { return subjects; }
             set { subjects = value; }
         }

XmlArrayItem負責指定數組中可能出現的元素類型，以及該類型對應的XML前綴
比如說創建如下的數組：
     Object obj = new Object["Physics", 123, "IT"];

生成XML如下格式：

< Cources >
     < CourceName > Physics </ CourceName >
     < CourceCode > 123 </ CourceCode >
     < CourceName > IT </ CourceName >
</ Cources >

     9.定義可空的對象引用
         如果某屬性爲null，在串行化時會忽略該屬性，可以顯示替代的信息，方法如下：

         [XmlElement(IsNullable = true )]
         public string Address
         {
             get { return address; }
             set { address = value; }
         }

在該位置，生成替代XML：
      <Address xsi:nil="true" />

     10.定義可忽略的字段/屬性
         [XmlIgnore()]
