面对对象之差异化的网络数据交互方式

这里来讲解一种简单的模式进行优化和解放这些繁琐的体力活.

用一个简单的示例程序来进行讲解:

定义一个实体类

   /// <summary>
    /// 实现属性通知接口
    /// </summary>
    public class GameInfo : INotifyPropertyChanged
    {
        private string _Name;

        public string Name
        {
            get { return _Name; }
            set { _Name = value; }
        }

        private int _Count;

        public int Count
        {
            get { return _Count; }
            set { _Count = value; }
        }

        private bool _isOpen;

        public bool IsOpen
        {
            get { return _isOpen; }
            set { _isOpen = value; }
        }

        public event PropertyChangedEventHandler PropertyChanged;

        protected void OnPropertyChanged(string propertyName, object value)
        {
            if (PropertyChanged != null)
            {
                PropertyChanged(this, new PropertyChangedEventArgs(propertyName));
            }
        }
    }

        //传统模式

        [WebMethod]
        public ChangeNameResult ChangeNameAI(string name)
        {
            GameInfo.Name = name;
            return new ChangeNameResult() {NewName = GameInfo.Name};
        }

        [WebMethod]
        public ChangeNameAndCountResult ChangeNameAndCountI(string name)
        {
            GameInfo.Name = name;
            GameInfo.Count++;
            return new ChangeNameAndCountResult() { NewName = GameInfo.Name, Count = GameInfo.Count };
        }

        [WebMethod]
        public ChangeALLResult ChangeALL(string name)
        {
            GameInfo.Name = name;
            GameInfo.Count++;
            GameInfo.IsOpen = !GameInfo.IsOpen
            return new ChangeALLResult() { NewName = GameInfo.Name, Count = GameInfo.Count,IsOpen = GameInfo.IsOpen};
        }

    /// <summary>
    /// 返回对象
    /// </summary>
    [Serializable]
    public class ResultObject
    {
        /// <summary>
        /// 如果有错误ErrorCode不为0
        /// </summary>
        public int ErrorCode { get; set; }

    }



    /// <summary>
    /// ChangeName 返回值
    /// </summary>
    [Serializable]
    public class ChangeNameResult : ResultObject
    {
        /// <summary>
        /// 新名称
        /// </summary>
        public string NewName { get; set; }
    }


    [Serializable]
    public class ChangeNameAndCountResult : ChangeNameResult
    {
        public int Count { get; set; }
    }

    [Serializable]
    public class ChangeALLResult : ChangeNameResult
    {
        public  bool IsOpen { get; set; }
    }

下面是差异修改模式示例:

 /// <summary>
    /// 通用返回
    /// </summary>
    [Serializable]
    public class ValueChangeResultObject : ResultObject
    {
        /// <summary>
        /// 统一返回值
        /// </summary>
        public string ResultStr { get; set; }
    }

    /// <summary>
    /// 返回对象
    /// </summary>
    [Serializable]
    public class ResultObject
    {
        /// <summary>
        /// 如果有错误ErrorCode不为0
        /// </summary>
        public int ErrorCode { get; set; }

    }

       //差异数据返回模式
        private string ChangeValues = "";
        [WebMethod]
        public string ChangeNameAndCountI(string name)
        {
            GameInfo.Name = name;
            GameInfo.Count++;
            return GetResult();
        }

        [WebMethod]
        public ValueChangeResultObject ChangeNameAII(string name)
        {
            GameInfo.Name = name;
            return GetResult();
        }

        [WebMethod]
        public ChangeALLResult ChangeALL(string name)
        {
            GameInfo.Name = name;
            GameInfo.Count++;
            GameInfo.IsOpen = !GameInfo.IsOpen
            return GetResult();
        }



        /// <summary>
        /// 获取通用返回方法
        /// </summary>
        /// <returns></returns>
        public ValueChangeResultObject GetResult()
        {
            return new ValueChangeResultObject() { ResultStr = ChangeValues };
        }


        [WebMethod]
        public string InitChangeObject()
        {
            GameInfo.PropertyChanged += new System.ComponentModel.PropertyChangedEventHandler(GameInfo_PropertyChanged);
        }


        private void GameInfo_PropertyChanged(object sender, System.ComponentModel.PropertyChangedEventArgs e)
        {
            //这边自定一个比较简单的返回结构
            //字段1:值1;
            //字段1:值1;字段2:值2;
            ChangeValues += e.PropertyName + ":" + typeof (GameInfo).GetProperty(e.PropertyName).GetValue() + ";"
                
        }
