深度解析XML的結構與類映射

• XML概述

• XmlElement

• XmlAttribute

• 類型定義與XML結構的映射

• XmlElement

• XmlAttribute

{
    []
    IntValue { ; ; }
    []
    StrValue { ; ; }
}

• InnerText

{
    []
    IntValue { ; ; }
    []
    StrValue { ; ; }
}

• 重命名節點名稱

()]
{
    [()]
    IntValue { ; ; }
    [()]
    StrValue { ; ; }
}

• 列表和數組的序列化

()]
: { }

• 列表和數組的做為數據成員的序列化

{
    Class3 { ; ; }
    [()]
    [()]
    List { ; ; }
}

{
    Class3 { ; ; }
    [()]
    List { ; ; }
}

• 類型繼承與反序列化

{ }
[()]
: {
    [()]
    AA { ; ; }
    [()]
    BB { ; ; }
}
[()]
: {
    [()]
    CC { ; ; }

    [()]
    DD { ; ; }
}
{
    [(()),
    (())]
    List { ; ; }
}

{
    []    IntValue { ; ; }
    StrValue { ; ; }
    Url;
}

• 強制指定成員的序列化順序

{
    [(Order )]
    StrValue { ; ; }
    [(Order )]
    Url;
}

• 反序列化

• XML數據讀寫代碼示例

order GetOrderById();
xml XmlSerialize(order, UTF8);
order2 XmlDeserialize(xml, UTF8);
