C# 入门操作XML文件实例

首先看下XML文件的结构：

<?xml version="1.0" encoding="utf-8" ?>
<List>

  <Item id="81" country="Japan"></Item>
  <Item id="852" country="香港特别行政区"></Item>
  <Item id="886" country="台灣"></Item>
  <Item id="86" country="中国"></Item>
  <Item id="213" country="Algeria"></Item>
  <Item id="54" country="Argentina"></Item>
  <Item id="61" country="Australia"></Item>
  <Item id="880" country="Bangladesh"></Item>
  <Item id="591" country="Bolivia"></Item>
  <Item id="673" country="Brunei"></Item>
  <Item id="1" country="USA"></Item>
  <Item id="56" country="Chile"></Item>
  <Item id="57" country="Colombia"></Item>
  <Item id="506" country="Costa Rica"></Item>  
  <Item id="357" country="Cyprus"></Item>
  <Item id="593" country="Ecuador"></Item>
  <Item id="20" country="Egypt"></Item>
  <Item id="33" country="France"></Item>
  <Item id="502" country="Guatemala"></Item>
  <Item id="504" country="Honduras"></Item>
  <Item id="91" country="India"></Item>
  <Item id="62" country="Indonesia"></Item>
  <Item id="353" country="Ireland"></Item>
  <Item id="962" country="Jordan"></Item>
</List>

一个简单的国家(地区)电话编号对应的国家(地区)

需求如下：根据代号查找国家

        /// <summary>
        /// 根据国家电话代号查找国家
        /// </summary>
        /// <param name="code">国家电话代号</param>
        /// <returns>国家名称</returns>
        public string GetCountryByCode(string code)
        {
            string count = "";

            string xmlfile = HttpContext.Current.Server.MapPath("~/XML/CodeToCountry/country.xml");

            System.Xml.XmlDocument doc = new System.Xml.XmlDocument();
            doc.Load(xmlfile);
            System.Xml.XmlNodeList nodes = doc.SelectNodes("List/Item");
            foreach (System.Xml.XmlNode item in nodes)
            {
                if (code == item.Attributes["id"].Value)
                {
                    count = item.Attributes["country"].Value;
                }
            }
            return count;
        }
