Serializing

1、序列化一個對像

代碼 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);

結果

{
"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、序列化一個對像的集合

代碼 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);

結果

代碼 [
{
"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

代碼 [

1、反序列化為一個對像

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

2、反序列化為一個對像的集合

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