    }

Serializing

1、序列化一个对像

timeLine obj =new timeLine();
        obj.created_at ="2010-7-15";
        obj.id =2589;
        obj.mms_img_pre ="http://www.abc.com";
        obj.text ="message text";
        obj.user = u;

        this.Literal1.Text = JsonConvert.SerializeObject(obj, Formatting.Indented);

结果

{
    "created_at": "2010-7-15",
    "text": "message text",
    "id": 2589,
    "mms_img_pre": "http://www.abc.com",
    "user": {
        "name": "jack",
        "screen_name": null,
        "location": "shenzhen"
    }
}

2、序列化一个对像的集合

userInfo u =new userInfo();
        u.name ="jack";
        u.location ="shenzhen";

        timeLine obj =new timeLine();
        obj.created_at ="2010-7-15";
        obj.id =2589;
        obj.mms_img_pre ="http://www.abc.com";
        obj.text ="message text";
        obj.user = u;

        timeLine obj2 =new timeLine();
        obj2.created_at ="2010-7-15";
        obj2.id =2589;
        obj2.mms_img_pre ="http://www.abc.com";
        obj2.text ="message text";

        List<timeLine> tls =new List<timeLine>();
        tls.Add(obj);
        tls.Add(obj2);

        this.Literal1.Text = JsonConvert.SerializeObject(tls, Formatting.Indented);

结果

[
    {
        "created_at": "2010-7-15",
        "text": "message text",
        "id": 2589,
        "mms_img_pre": "http://www.abc.com",
        "user": {
            "name": "jack",
            "screen_name": null,
            "location": "shenzhen"
        }
    },
    {
        "created_at": "2010-7-15",
        "text": "message text",
        "id": 2589,
        "mms_img_pre": "http://www.abc.com",
        "user": null
    }
]

Deserializing

原始JSON字符串

        }

1、反序列化为一个对像

timeLine msg = JsonConvert.DeserializeObject<timeLine>(json_input);

2、反序列化为一个对像的集合

List<timeLine> msg = JsonConvert.DeserializeObject<List<timeLine>>(json_input);
