Json帮助类以及如何使用

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;
    }
}

反序列化：
类名 对象 = (类名)JSONHelper.Deserialize<类名>(json字符串);

序列化：
string json字符串 = JSONHelper.Serialize<类名>(对象);
