利用.NET 3.5以后的扩展方法重写JSON序列化和反序列化，在代码可读性和可维护性上更加加强了。
首先是不使用扩展方法的写法
定义部分：
/// <summary> /// JSON序列化反序列化工具 /// </summary> public classJSONControl { /// <summary> /// JSON序列化 /// </summary> /// <typeparam name="T"></typeparam> /// <param name="_Object"></param> /// <returns></returns> public staticString JsonSerializer<T>(T _Object) { using(MemoryStream TempMemoryStream =newMemoryStream()) { String MySerializationString = String.Empty; DataContractJsonSerializer MyDataContractJsonSerializer =newDataContractJsonSerializer(typeof(T)); MyDataContractJsonSerializer.WriteObject(TempMemoryStream, _Object); MySerializationString = Encoding.UTF8.GetString(TempMemoryStream.ToArray()); returnMySerializationString; } } /// <summary> /// 反序列化 /// </summary> /// <typeparam name="T"></typeparam> /// <param name="_JsonString"></param> /// <returns></returns> public staticT JsonDeserializer<T>(String _JsonString) { using(MemoryStream TempMemoryStream =newMemoryStream(Encoding.UTF8.GetBytes(_JsonString))) { DataContractJsonSerializer MyDataContractJsonSerializer =newDataContractJsonSerializer(typeof(T)); return(T)MyDataContractJsonSerializer.ReadObject(TempMemoryStream); } } }
使用部分：
/// <summary> /// 场景控制对象 /// </summary> public classSceneControl { /// <summary> /// 临时序列化对象 /// </summary> [DataContract] public classTempClass { /// <summary> /// 属性1 /// </summary> [DataMember(Name ="PRoperty1")] publicString Property1 {get;set; } /// <summary> /// 属性2 /// </summary> [DataMember(Name ="Property2")] publicString Property2 {get;set; } } /// <summary> /// 测试 /// </summary> public voidTest() { String JsonString ="{'Property1':'111','Property2':'2'}"; TempClass MyTempClass = JSONControl.JsonDeserializer<TempClass>(JsonString); } }
然后是使用扩展方法的写法
定义部分：
/// <summary> /// JSON序列化反序列化工具 /// </summary> public static classJSONControl { /// <summary> /// JSON序列化 /// </summary> /// <typeparam name="T"></typeparam> /// <param name="_Object"></param> /// <returns></returns> public staticString ObjectToJson<T>(thisT _Object) { using(MemoryStream TempMemoryStream =newMemoryStream()) { String MySerializationString = String.Empty; DataContractJsonSerializer MyDataContractJsonSerializer =newDataContractJsonSerializer(typeof(T)); MyDataContractJsonSerializer.WriteObject(TempMemoryStream, _Object); MySerializationString = Encoding.UTF8.GetString(TempMemoryStream.ToArray()); returnMySerializationString; } } /// <summary> /// JSON反序列化 /// </summary> /// <typeparam name="T"></typeparam> /// <param name="_JsonString"></param> /// <returns></returns> public staticT JsonToObject<T>(thisString _JsonString) { using(MemoryStream TempMemoryStream =newMemoryStream(Encoding.UTF8.GetBytes(_JsonString))) { DataContractJsonSerializer MyDataContractJsonSerializer =newDataContractJsonSerializer(typeof(T)); return(T)MyDataContractJsonSerializer.ReadObject(TempMemoryStream); } } }
使用部分：
/// <summary> /// 场景控制对象 /// </summary> public classSceneControl { /// <summary> /// 临时序列化对象 /// </summary> [DataContract] public classTempClass { /// <summary> /// 属性1 /// </summary> [DataMember(Name ="Property1")] publicString Property1 {get;set; } /// <summary> /// 属性2 /// </summary> [DataMember(Name ="Property2")] publicString Property2 {get;set; } } /// <summary> /// 测试 /// </summary> public voidTest() { String JsonString ="{'Property1':'111','Property2':'2'}"; TempClass MyTempClass = JsonString.JsonToObject<TempClass>(); } }
