需要先引用命名空间
Newtonsoft.Json 和 Newtonsoft.Json.Linq
1.可自行网上下载 Newtonsoft.Json.dll ，在项目中添加引用
2.或者是直接使用VS的内置NuGet包管理器中搜索Newtonsoft.Json 安装到指定项目
1.针对简单的json串
需要处理的json串
“{
“message”: “操作成功”,
“data”: “This is a data”,
“success”: “true”
}”
解析方法：
string json = "{"message": "操作成功","data": "This is a data","success": "true"}";
Object obj = JsonConvert.DeserializeObject(json);
Newtonsoft.Json.Linq.JObject js = obj as Newtonsoft.Json.Linq.JObject;//把上面的obj转换为 Jobject对象
string data = js["data"].ToString();
补充：
dynamic model = JObject.Parse("{"value":"巧克力1","color":"#173177"}");
string sss = model.value;
不知道key的情况下用下面程序拿到key和value
JObject json = (JObject)JsonConvert.DeserializeObject(listdata);
string openId = json["OpenID"].ToString();
foreach (var jp in json)
{
string key = jp.Key.ToString();
string val = jp.Value.ToString();
}
2.针对简单的json串数组
需要处理的json串数组
[
{
“deviceID”: “110722”,
“discloseTime”: “2019-03-08 01:00:00”,
“projectId”: “24”
},
{
“deviceID”: “110732”,
“discloseTime”: “2019-03-08 15:40:12”,
“projectId”: “24”
},
{
“deviceID”: “110735”,
“discloseTime”: “2019-03-08 16:40:12”,
“projectId”: “24”
}
]
解析：
string json = "[{"deviceID": "110722","discloseTime": "2019-03-08 01:00:00","projectId": "24"},{"deviceID": "110732","discloseTime": "2019-03-08 15:40:12","projectId": "24"},{"deviceID": "110735","discloseTime": "2019-03-08 16:40:12","projectId": "24"}]";
Object obj = JsonConvert.DeserializeObject(json);
Newtonsoft.Json.Linq.JArray jarray = obj as Newtonsoft.Json.Linq.JArray;//把上面的obj转换为 Jobject对象
List<Body> bodyList = new List<Body>();
for (int i = 0; i < jarray.Count; i++)
{
string listdata = jarray[0].ToString();
Object obj1 = JsonConvert.DeserializeObject(listdata);
Newtonsoft.Json.Linq.JObject js1 = obj1 as Newtonsoft.Json.Linq.JObject;//把上面的obj转换为 Jobject对象
Body body = new Body
{
DeviceID= js1["deviceID"].ToString(),
DiscloseTime = js1["discloseTime"].ToString(),
ProjectId = js1["projectId"].ToString()
};
bodyList.Add(body);
}
3.针对复合的json串
需要处理的json数据
{
“message”: “操作成功”,
“data”: [
{
“deviceID”: “110722”,
“discloseTime”: “2019-03-08 01:00:00”,
“projectId”: “24”
},
{
“deviceID”: “110732”,
“discloseTime”: “2019-03-08 15:40:12”,
“projectId”: “24”
},
{
“deviceID”: “110735”,
“discloseTime”: “2019-03-08 16:40:12”,
“projectId”: “24”
}
],
“success”: ”true“
}
解析：
List<Body> bodyList = new List<Body>();
Object obj = JsonConvert.DeserializeObject(json);
Newtonsoft.Json.Linq.JObject js = obj as Newtonsoft.Json.Linq.JObject;//把上面的obj转换为 Jobject对象
JArray jarray = (JArray)js["data"];
for (int i = 0; i < jarray.Count; i++)
{
string data = jarray[0].ToString();
Object obj1 = JsonConvert.DeserializeObject(data);
Newtonsoft.Json.Linq.JObject js1 = obj1 as Newtonsoft.Json.Linq.JObject;//把上面的obj转换为 Jobject对象
Body body = new Body
{
DeviceID = js1["deviceID"].ToString(),
DiscloseTime = js1["discloseTime"].ToString(),
ProjectId = js1["projectId"].ToString()
};
bodyList.Add(body);
}
