VS 2005中xml文件和实体类(List)之间的转换

在进行数据传时，我们可能要用到xml来承担

这就需要将获得的xml转换到我们的实体类，或者将我们的实体类序列化为xml传送出去

------------------------------------------------------------------------------------------------------------------------------

//示例类

public class XmlData    {        private string _Bassetcard;        private string _Coperatorname;        private string _Cregister;        private string _Cwarehouseid;        private string _Freplenishflag;        private string _Vbillcode;        private string _Vuserdef10;                public string Bassetcard        {            get { return _Bassetcard; }            set { _Bassetcard = value; }        }        public string Coperatorname        {            get { return _Coperatorname; }            set { _Coperatorname = value; }        }        public string Cregister        {            get { return _Cregister; }            set { _Cregister = value; }        }        public string Cwarehouseid        {            get { return _Cwarehouseid; }            set { _Cwarehouseid = value; }        }        public string Freplenishflag        {            get { return _Freplenishflag; }            set { _Freplenishflag = value; }        }        public string Vbillcode        {            get { return _Vbillcode; }            set { _Vbillcode = value; }        }        public string Vuserdef10        {            get { return _Vuserdef10; }            set { _Vuserdef10 = value; }        }    }

1：从xml到我们的实体类

/// <summary>        /// 这里的xml是我们传送数据时接收的字符串，        /// 这里采用先从本地加载，再从loadmxl来加载        /// </summary>        /// <returns></returns>        public static List<XmlData> GetFromXml()        {            List<XmlData> items = new List<XmlData>();            XmlDocument doc = new XmlDocument();            doc.Load(@"G:\sda.xml");                        //获得字符串            //加载文档            //此字符串是我们接收的字符串            string xml = doc.OuterXml;            doc.LoadXml(xml);            XmlNode rootNode = doc.ChildNodes[1];            foreach (XmlNode node in rootNode.ChildNodes)            {                XmlData item = new XmlData();                if (node.NodeType == XmlNodeType.Element)                {                    foreach (XmlElement element in node.ChildNodes)                    {                        switch (element.Attributes["name"].Value)                        {                            case "bassetcard":                                item.Bassetcard = element.Attributes["value"].Value;                                break;                            case "coperatorname":                                item.Coperatorname = element.Attributes["value"].Value;                                break;                            case "cregister":                                item.Cregister = element.Attributes["value"].Value;                                break;                            case "cwarehouseid":                                item.Cwarehouseid = element.Attributes["value"].Value;                                break;                            case "freplenishflag":                                item.Freplenishflag = element.Attributes["value"].Value;                                break;                            case "vbillcode":                                item.Vbillcode = element.Attributes["value"].Value;                                break;                            case "vuserdef10":                                item.Vuserdef10 = element.Attributes["value"].Value;                                break;                        }                    }                    items.Add(item);                }            }            return items;        }

2：将我们的实体类转换程xml字符串来传送

/// <summary>        /// 获得要传送的字符串        /// </summary>        /// <returns></returns>        public static string SendToXml()        {            //需要序列化的实体            List<XmlData> dataList = GetFromXml();            XmlDocument doc = new XmlDocument();            //声明            XmlDeclaration xd;            xd = doc.CreateXmlDeclaration("1.0", "utf-8", "yes");            XmlElement root = doc.CreateElement("volist");            if (dataList != null)            {                foreach (XmlData item in dataList)                {                    XmlElement elenent = doc.CreateElement("vo");                    root.AppendChild(elenent);                    Entitiytoxml(doc, root, item, elenent);                }                doc.AppendChild(root);                //添加声明                doc.InsertBefore(xd, root);                doc.Save(Console.Out);            }                        return doc.OuterXml;        }        /// <summary>        /// 处理结点        /// </summary>        /// <param name="doc">文档</param>        /// <param name="root"></param>        /// <param name="item"></param>        /// <param name="element"></param>        private static void Entitiytoxml(XmlDocument doc, XmlElement root, XmlData item, XmlElement element)        {            System.Reflection.PropertyInfo[] propertyInfo = typeof(XmlData).GetProperties(System.Reflection.BindingFlags.Public | System.Reflection.BindingFlags.Instance);            XmlElement xmlElement = null;            foreach (System.Reflection.PropertyInfo pinfo in propertyInfo)            {                xmlElement = doc.CreateElement("field");                if (pinfo != null)                {                    string name = pinfo.Name;                    string value = string.Empty;                    if (pinfo.GetValue(item, null) != null)                    {                        value = pinfo.GetValue(item, null).ToString();                    }                    //添加属性到field                    XmlAttribute attr = doc.CreateAttribute("name");                    attr.Value = name;                    xmlElement.Attributes.Append(attr);                    XmlAttribute attr1 = doc.CreateAttribute("value");                    attr1.Value = value;                    xmlElement.Attributes.Append(attr1);                    XmlAttribute attr2 = doc.CreateAttribute("type");                    attr2.Value = pinfo.Name.GetType().ToString();                    xmlElement.Attributes.Append(attr2);                    element.AppendChild(xmlElement);                }            }            root.AppendChild(element);        }
