NET JSON除了油实体类转换DLL之外，还有动态的，也就是NET本身自己就支持的东西，顺便提一下使用WebService的时候，哪里需要Webservice的方法哪里的config里面就要配置Models 也就是第一次引用的时候自动生成的那一段东东

XML的

using System;using System.Collections.Generic;using System.Dynamic;using System.Linq;using System.Text;using System.Threading.Tasks;using System.Xml.Linq;namespace Zemt.BPM.Common{    public static class XmlUtil    {        public static string ToXml(dynamic dynamicObject)        {            DynamicXElement xmlNode = dynamicObject;            return xmlNode.XContent.ToString();        }        public static dynamic ToObject(string xml, dynamic dynamicResult)        {            XElement element = XElement.Parse(xml);            dynamicResult = new DynamicXElement(element);            return dynamicResult;        }        public static dynamic ToObject(string xml)        {            XElement element = XElement.Parse(xml);            dynamic dynamicResult = new DynamicXElement(element);            return dynamicResult;        }    }    public class DynamicXElement : DynamicObject    {        public DynamicXElement(XElement node)        {            this.XContent = node;        }        public DynamicXElement()        {        }        public DynamicXElement(String name)        {            this.XContent = new XElement(name);        }        public XElement XContent        {            get;            private set;        }        public override bool TrySetMember(            SetMemberBinder binder, object value)        {            XElement setNode = this.XContent.Element(binder.Name);            if (setNode != null)                setNode.SetValue(value);            else            {                //creates an XElement without a value.                if (value.GetType() == typeof(DynamicXElement))                    this.XContent.Add(new XElement(binder.Name));                else                    this.XContent.Add(new XElement(binder.Name, value));            }            return true;        }        public override bool TryGetMember(            GetMemberBinder binder, out object result)        {            XElement getNode = this.XContent.Element(binder.Name);            IList<XElement> nodes = this.XContent.Elements(binder.Name).ToList<XElement>();            if (nodes.Count == 1)            {                result = new DynamicXElement(getNode);            }            else if(nodes.Count > 1)            {                IList<DynamicXElement> des = new List<DynamicXElement>();                foreach (var e in nodes)                {                    des.Add(new DynamicXElement(e));                }                result = des;            }            else            {                result = new DynamicXElement(binder.Name);            }            return true;        }        public override bool TryConvert(    ConvertBinder binder, out object result)        {            if (binder.Type == typeof(String))            {                result = this.XContent.Value;                return true;            }            else            {                result = null;                return false;            }        }    }}
