1.反序列化xml文件：

var xmls = XmlHelper.Load<TagList>(ServerExtension.MapPath("Configs/TagList.Config", true));
            var tagList = xmls.tagList;

2.xml文件示例：

<?xml version="1.0" encoding="utf-8"?>
<!-- ================== TAGS配置 ================== -->
<Tags xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema">

	<Tag key="tag0" value="项目Note" count="0" isNew="false"/>
	<Tag key="tag1" value="worknote" count="0" isNew="false"/>
	<Tag key="tag2" value="C#" count="0" isNew="false"/>

	<Tag key="tag13" value="ElementUI" count="0" isNew="false"/>
	
</Tags>

3.xml文件model：

using System;
using System.Collections.Generic;
using System.Xml.Serialization;

namespace Jabil.Web.Models
{
    [XmlRoot(ElementName = "Tags")]
    public class TagList
    {
        List<Tag> tags = new List<Tag>();
        [XmlElement(ElementName = "Tag")]
        public List<Tag> tagList
        {
            get { return tags; }
            set { tags = value; }
        }
    }

    public class Tag
    {
        [XmlAttribute(AttributeName = "key")]
        public string key
        {
            get;
            set;
        }

        [XmlAttribute(AttributeName = "value")]
        public string value
        {
            get;
            set;
        }

        [XmlAttribute(AttributeName = "count")]
        public int count {
            get;
            set;
        }

        [XmlAttribute(AttributeName = "isNew")]
        public bool isNew {
            get;
            set;
        }
    }
}
