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：

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);
}
}
}
