Asp.Net Newtonsoft.Json使用教程

json序列化和反序列化的使用教程

实体

public class wendaModel

{

    private string _title;

    private string _cons;

    public string title

    {

        set { _title = value; }

        get { return _title; }

    }

    public string cons

    {

        set { _cons = value; }

        get { return _cons; }

    }

}

1、对象转换为json字符串（序列化）

wendaModel model = new wendaModel();

model.title = "json";

model.cons = "asp.net";

string json = Newtonsoft.Json.JsonConvert.SerializeObject(model);

Response.Write(json);

//输入结果：{"title":"json","cons":"asp.net"}

2、List转换为json字符串（序列化）

List<wendaModel> list = new List<wendaModel>();

for (int i = ; i < ; i++)

{

    wendaModel model = new wendaModel();

    model.title = "json" + i.ToString();

    model.cons = "asp.net" + i.ToString();

    list.Add(model);

}

string json = Newtonsoft.Json.JsonConvert.SerializeObject(list);

Response.Write(json);

//输出结果：[{"title":"json0","cons":"asp.net0"},{"title":"json1","cons":"asp.net1"},{"title":"json2","cons":"asp.net2"}]

3、json字符串转换为对象（反序列化）

string json = "{\"cons\":\"asp.net\",\"title\":\"json\"}";

wendaModel model = Newtonsoft.Json.JsonConvert.DeserializeObject<wendaModel>(json);

Response.Write(model.title + "=" + model.cons);

//输出结果：json=asp.net

4、json字符串转换为对象（反序列化）

string json = "[{\"cons\":\"asp.net2\",\"title\":\"json2\"},{\"cons\":\"asp.net1\",\"title\":\"json1\"}]";

List<wendaModel> list = Newtonsoft.Json.JsonConvert.DeserializeObject<List<wendaModel>>(json);

foreach (var item in list)

{

     Response.Write(item.title);

}
