C#通过XML节点属性/属性值读取写入XML操作代码实例

1.XML的内容如下：

复制代码 代码如下:


 
 

2.获得XML文档

复制代码 代码如下:
private static string url = AppDomain.CurrentDomain.SetupInformation.Applicationbase+"Config\config.xml";
        private  Xmldocument xmlDoc;
        private XmlNode root;
        public static string Title;
        public  XMLHandler()
        {
            xmlDoc = new Xmldocument();
            LoadConfig();
        }

        private  void LoadConfig()
        {
            try
            {
                xmlDoc.Load(url);
                root = xmlDoc.SelectSingleNode("root");
            }
            catch (Exception e)
            {
                throw e;
            }
        }

3.通过属性名称读取XML节点中的内容

复制代码 代码如下:
public TitleModel GetTitle()
        {
            try
            {
                TitleModel title = new TitleModel();
                XmlNode node = root.FirstChild;
                if(node!=null)
                {
                    foreach (XmlNode nd in node.ChildNodes)
                    {
                        XmlElement element = (XmlElement)nd;
                        if (element.GetAttribute("name") == "显示文字")
                        {
                            title.Title = nd.InnerText;
                        }
                        else if (element.GetAttribute("name") == "字体尺寸")
                        {
                            title.FontSize = Convert.ToInt32(nd.InnerText);
                        }
                        else if (element.GetAttribute("name") == "颜色")
                        {
                            title.FontColor = FontColor(nd.InnerText);
                        }
                        else if (element.GetAttribute("name") == "字体")
                        {
                            title.FontFamily = nd.InnerText;
                        }
                    }
                }
                return title;       
            }
            catch (Exception e)
            {       
                throw e;
            }

        }

4.通过属性读取XML中节点的属性值

复制代码 代码如下:
public List GetMenuString()
        {
            try
            {
                List list=new List();
                XmlNode menu = root.ChildNodes[1];
                if (menu != null)
                {
                    foreach (XmlNode node in menu.ChildNodes)
                    {
                        XmlElement element = (XmlElement)node;
                        list.Add(element.GetAttribute("name"));
                    }
                }
                return list;
            }
            catch (Exception e)
            {
                throw e;
            }
        }

5.通过节点获取XML节点中的内容

复制代码 代码如下:
public string GetMainBackground()
        {
            string url ="Images/mainjpg";
            try
            {
                XmlNode node = root.LastChild;
                if (node != null)
                {
                    url =  node.InnerText;
                }
                return url;
            }
            catch (Exception e)
            {
                throw e;
            }

        }
