C#实现String类型和json之间的相互转换功能示例

////Donet2.0 需要添加引用// 从一个对象信息生成Json串public static string ObjectToJson(object obj){   return JavaScriptConvert.SerializeObject(obj);}// 从一个Json串生成对象信息public static object JsonToObject(string jsonString,object obj){   return JavaScriptConvert.DeserializeObject(jsonString, obj.GetType());}//Donet3.5自带了DLL处理json串//注意引用：System.Runtime.Serialization，System.ServiceModel.Web
