XML反序列化：不同的XML架构映射到同一个C＃类 [英] XML deserialize: different xml schema maps to the same C# class

问题描述

我的一个程序的工作是从一个XML文件中读取客户名单，并将其反序列化到C＃类象下面这样：

One of the jobs of my program is to read customer list from a xml file and deserialize them into C# class like below:

<?xml version="1.0" encoding="utf-8"?>
<customers>
    <customer>
        <name>john</name>
        <id>1</id>
    </customer>
    <customer>
        <name>mike</name>
        <id>2</id>
    </customer>
</customers>

C＃类：

C# class:

[XmlRoot("customers")]
public class CustomerList {
        [XmlElement("customer")]
        public Customer[] Customers { get; set; }
}

public class Customer {
    [XmlElement("name")]
    public String Name {get; set;}

    [XmlElement("id")]
    public String Id {get; set;}
}

但最近客户想要的标签名从<$ c修改$ C>< ID> 到<代码> 像下面这样：

<?xml version="1.0" encoding="utf-8"?>
<customers>
    <customer>
        <name>john</name>
        <code>1</code>
    </customer>
    <customer>
        <name>mike</name>
        <code>2</code>
    </customer>
</customers>

有关代码将具有相同的含义与以前的标签'身份证'的价值。而且，他们希望这种转变过程中的程序应该修正，因此认识到在一段时间内这两个标签。

The value for 'code' will have the same meaning with previous tag 'id'. And they want that during transition the program should be amended so it recognizes both tags for a period of time.

有没有简单的方法来实现这一目标？谢谢你。

Is there any easy method to achieve that? Thanks.

推荐答案

？只要这两个标签不会在XML出现，这会奏效。

Why don't you use one private field and use two different getters/setters? As long as both tags do not appear in the XML, this will work.

[XmlRoot("customers")]
public class CustomerList {
    [XmlElement("customer")]
    public Customer[] Customers { get; set; }
}

public class Customer {
    private String _id;

    [XmlElement("name")]
    public String Name {get; set;}

    [XmlElement("id")]
    public String Id {get{return _id;} set{_id = value;}}

    [XmlElement("code")]
    public String Code {get{return _id;} set{_id = value;}}
}
