C#解析Json格式数据小结

最近，遇到了一些不同的Json格式的数据，需要做不同处理才能转化为想要得到的结果，这里总结一下。

第一种形式：status中是{}形式，对象

string json =
                 @"{'name':'Tom','province':'32','city':'1','location':'江苏 南京','status':{'created_at':'Thu Feb 26 21:04:34 +0800 2015','text':'哈哈'}}";

针对以上格式的数据，创建如下的两个结构体或类

    public struct Status
    {
        public string created_at { get; set; }
        public string text { get; set; }
    }

    public struct JsonData
    {
        public string name { get; set; }
        public string province { get; set; }
        public string city { get; set; }
        public string location { get; set; }
        public Status status;
    }

输出结果：

1 　　JavaScriptSerializer jsSerializer=new JavaScriptSerializer();
2   　JsonData jd = jsSerializer.Deserialize<JsonData>(json);
3  　 Response.Write(string.Format("name={0};province={1};city={2};location={3};status={4};",jd.name,jd.province,jd.city,jd.location,jd.status.created_at+jd.status.text));

 

第二种形式：status中是[]形式，数组

string json =
                @"{'name':'Tom','province':'32','city':'1','location':'江苏 南京','status':[{'created_at':'Thu Feb 26 21:04:34 +0800 2015','text':'哈哈'}]}";

针对以上格式的数据，创建如下的两个结构体或类

　　public struct Status
    {
        public string created_at { get; set; }
        public string text { get; set; }
    }
    public struct JsonData2
    {
        public string name { get; set; }
        public string province { get; set; }
        public string city { get; set; }
        public string location { get; set; }
        public List<Status> status;
    }

输出结果

     JavaScriptSerializer jsSerializer=new JavaScriptSerializer();
     JsonData2 jd = jsSerializer.Deserialize<JsonData2>(json);
     Response.Write(string.Format("name={0};province={1};city={2};location={3};status={4};",jd.name,jd.province,jd.city,jd.location,jd.status[0].created_at+jd.status[0].text));

 

 

项目应用：

json字符串：

    {
    "depart_id": 5,
    "depart_name": "人事部",
    "depart_source": "[{\"text\": \"\", \"type\": \"text\"},{\"text\": \"\", \"type\": \"image\"},{\"text\": \"\", \"type\": \"audio\"}]",
    "staff": {
        "name": "谭琳",
        "title": "部门经理",
        "image": "/2015/1/13/d2e2e3f2c2f8_2e4f5b.jpg",
        "id": 143375468
        }
     }

创建类：

public class DepatData
{
    public int depart_id = 0;
    public string depart_name = "";
    public string depart_source = "";
    public StaffData staff =new StaffData();

    public class StaffData
    {
        public string name = "";
        public string title = "";
        public string image = "";
        public string id = "";
    }
}

解析Json数据：

        DepatData d = JsonConvert.DeserializeObject<DepatData>(strJson);
        List<Dictionary<string, string>> depart_source =
            JsonConvert.DeserializeObject < List<Dictionary<string, string>>>(d.depart_source);
        
        //获取值
        int depart_id = d.depart_id;
        .......
        string text = depart_source[0]["text"];
        string type = depart_source[0]["type"];
        .......
