利用扩展方法重写JSON序列化和反序列化

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 class JSONControl
{
    /// <summary>
    /// JSON序列化
    /// </summary>
    /// <typeparam name="T"></typeparam>
    /// <param name="_Object"></param>
    /// <returns></returns>
    public static String JsonSerializer<T>(T _Object)
    {
        using (MemoryStream TempMemoryStream = new MemoryStream())
        {
            String MySerializationString = String.Empty;
            DataContractJsonSerializer MyDataContractJsonSerializer = new DataContractJsonSerializer(typeof(T));
            MyDataContractJsonSerializer.WriteObject(TempMemoryStream, _Object);
            MySerializationString = Encoding.UTF8.GetString(TempMemoryStream.ToArray());
            return MySerializationString;
        }

    }

    /// <summary>
    /// 反序列化
    /// </summary>
    /// <typeparam name="T"></typeparam>
    /// <param name="_JsonString"></param>
    /// <returns></returns>
    public static T JsonDeserializer<T>(String _JsonString)
    {
        using (MemoryStream TempMemoryStream = new MemoryStream(Encoding.UTF8.GetBytes(_JsonString)))
        {
            DataContractJsonSerializer MyDataContractJsonSerializer = new DataContractJsonSerializer(typeof(T));
            return (T)MyDataContractJsonSerializer.ReadObject(TempMemoryStream);
        }
    }
}

使用部分：

/// <summary>
/// 场景控制对象
/// </summary>
public class SceneControl
{
    /// <summary>
    /// 临时序列化对象
    /// </summary>
    [DataContract]
    public class TempClass
    {
        /// <summary>
        /// 属性1
        /// </summary>
        [DataMember(Name = "Property1")]
        public String Property1 { get; set; }

        /// <summary>
        /// 属性2
        /// </summary>
        [DataMember(Name = "Property2")]
        public String Property2 { get; set; }
    }

    /// <summary>
    /// 测试
    /// </summary>
    public void Test()
    {
        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 class JSONControl
{
     /// <summary>
     /// JSON序列化
     /// </summary>
     /// <typeparam name="T"></typeparam>
     /// <param name="_Object"></param>
     /// <returns></returns>
     public static String ObjectToJson<T>(this T _Object)
     {
         using (MemoryStream TempMemoryStream = new MemoryStream())
         {
             String MySerializationString = String.Empty;
             DataContractJsonSerializer MyDataContractJsonSerializer = new DataContractJsonSerializer(typeof(T));
             MyDataContractJsonSerializer.WriteObject(TempMemoryStream, _Object);
             MySerializationString = Encoding.UTF8.GetString(TempMemoryStream.ToArray());
             return MySerializationString;
         }

     }

     /// <summary>
     /// JSON反序列化
     /// </summary>
     /// <typeparam name="T"></typeparam>
     /// <param name="_JsonString"></param>
     /// <returns></returns>
     public static T JsonToObject<T>(this String _JsonString)
     {
         using (MemoryStream TempMemoryStream = new MemoryStream(Encoding.UTF8.GetBytes(_JsonString)))
         {
             DataContractJsonSerializer MyDataContractJsonSerializer = new DataContractJsonSerializer(typeof(T));
             return (T)MyDataContractJsonSerializer.ReadObject(TempMemoryStream);
         }
     }
}

使用部分：

/// <summary>
/// 场景控制对象
/// </summary>
public class SceneControl
{
    /// <summary>
    /// 临时序列化对象
    /// </summary>
    [DataContract]
    public class TempClass
    {
        /// <summary>
        /// 属性1
        /// </summary>
        [DataMember(Name = "Property1")]
        public String Property1 { get; set; }

        /// <summary>
        /// 属性2
        /// </summary>
        [DataMember(Name = "Property2")]
        public String Property2 { get; set; }
    }

    /// <summary>
    /// 测试
    /// </summary>
    public void Test()
    {
        String JsonString = "{'Property1':'111','Property2':'2'}";
        TempClass MyTempClass = JsonString.JsonToObject<TempClass>();
    }
}
