Json協助類以及如何使用

標籤：des   style   class   code   color   width   

首先要添加引用System.Runtime.Serialization.

public class JSONHelper{    public static string Serialize<T>(T obj)    {        System.Runtime.Serialization.Json.DataContractJsonSerializer serializer = new System.Runtime.Serialization.Json.DataContractJsonSerializer(obj.GetType());        MemoryStream ms = new MemoryStream();        serializer.WriteObject(ms, obj);        string retVal = Encoding.UTF8.GetString(ms.ToArray());        return retVal;    }    public static T Deserialize<T>(string json)    {        T obj = Activator.CreateInstance<T>();        MemoryStream ms = new MemoryStream(Encoding.UTF8.GetBytes(json));        System.Runtime.Serialization.Json.DataContractJsonSerializer serializer = new System.Runtime.Serialization.Json.DataContractJsonSerializer(obj.GetType());        obj = (T)serializer.ReadObject(ms);        ms.Close();        return obj;    }}

 

還原序列化：類名 對象 = (類名)JSONHelper.Deserialize<類名>(json字串);序列化：string json字串 = JSONHelper.Serialize<類名>(對象);
