C#中Xml与对象Model的相互转换

    public class XMLSerialize

        {
            using (StringWriter sw = new StringWriter())
            {
                Type t = obj.GetType();
                XmlSerializer serializer = new XmlSerializer(obj.GetType());
                serializer.Serialize(sw, obj);
                sw.Close();
                return sw.ToString();
            }
        }
 
        public static T DESerializer<T>(string strXML) where T:class
        {
            try

                return null;

    }
}

例子:

<?xml version="1.0" encoding="utf-8" ?>
<envelope>
    <header>
        <version port="1111" host="www.baidu.com">successfuly</version>
        <timestamp>20211216081218</timestamp>
    </header>
    <response type="cities" product="hotel">
        <cities>
            <city>
                <code value="zg" />
                <city_tax value="true" />
                <names>
                    <name language="fr" value="ABANO TERME - PADOUE" />
                    <name language="en" value="ABANO TERME - PADUE" />
                    <name language="nl" value="ABANO TERME - PADUE" />
                </names>
            </city>
            <city>
                <code value="hk" />
                <city_tax value="false" />
                <names>
                    <name language="fr" value="ABBADIA SAN SALVATORE - SIENNE" />
                    <name language="en" value="ABBADIA SAN SALVATORE - SIENA" />
                    <name language="nl" value="ABBADIA SAN SALVATORE - SIENA" />
                </names>
            </city>
        </cities>
    </response>

可以使用Visual Studio自带的Xml对象模型类

1.首先Ctrl+C复制你需要生成的Xml文档内容

2.找到编辑=》选择性粘贴=》将Xml粘贴为类，这样就可以了

XmlType（TypeName=“”）为<>的开始Name

XmlAttribute为内部关键字

XmlText()是获取<>123123的Value
