XML的创建与读取

//创建xml
 public ActionResult XML()
        {
            SearchArticle search = new SearchArticle
            {
                SearchType = SearchTypeEnum.Top,
                Top = 4,
                Status = StatusEnum.Active,
            };
           
            IList<ArticleInfo> list = article.SearchArticle(search);
            
            int count = list.Count;

            XmlWriterSettings settings = new XmlWriterSettings();
            settings.Indent = true;//自动缩进
            settings.Encoding = new UTF8Encoding(false);

            settings.NewLineChars = Environment.NewLine;
            using (XmlWriter xmlwriter = XmlWriter.Create("D:\\1.xml",settings))
            {

                xmlwriter.WriteStartDocument(false);
                xmlwriter.WriteStartElement("root");
                for (int i = 0; i < count; i++)
                {
                    ArticleInfo info = list[i];
                    string articleid = info.ArticleID.ToString();
                    xmlwriter.WriteElementString("articleId", articleid);
                }
            }
            return View();
        }

 

 

//读取xml
public string ReadXml(string str)
        {
            XmlDocument xmlDoc = new XmlDocument();
            xmlDoc.Load("Config.xml");

            XmlNodeList nodeList = xmlDoc.SelectSingleNode("setup").ChildNodes;//获取bookstore节点的所有子节点

            foreach (XmlNode xn in nodeList)//遍历所有子节点
            {
                XmlElement xe = (XmlElement)xn;//将子节点类型转换为XmlElement类型


                XmlNodeList nls = xe.ChildNodes;//继续获取xe子节点的所有子节点
                foreach (XmlNode xn1 in nls)//遍历
                {
                    XmlElement xe2 = (XmlElement)xn1;//转换类型
                    if(xe2.Name == str)//如果找到
                    {
                        return xe2.Value.ToString();
                        break;//找到退出来就可以了
                    }
                }
                break;
            }
