Use C language to receive JSON strings

Use C# Language to carry on json Receiving of string

Using tools ：vs2019
Method ：

1. Get what you want to accept json object , such as ：

{
“face_token”: “fid”,
“user_list”: [
{
“group_id” : “test1”,
“user_id”: “u333333”,
“user_info”: “Test User”,
“score”: 99.3
}
]
}
2. Prepare an entity class to accept json object

3. First step json Objects are copied to the clipboard , Then proceed as follows

The result is ：

It can be seen that RootObject Medium user_List[] The array contains User_List class

Use code to accept object code

 var result = Client().FaceGetlist(userID, groupID);


                JToken jToken = JToken.Parse(result.ToString());
                // Get error code 
                int error_code = int.Parse(jToken["error_code"].ToString());
                if (error_code == 0)
                {
    
                    string resultString = Convert.ToString(result);
                    Rootobject rootobject = JsonConvert.DeserializeObject<Rootobject>(resultString);
                    foreach (var list in rootobject.result.face_list)
                    {
    
                        faceTokenString.Add(Convert.ToString(list.face_token));
                    }
                }

Rootobject rootobject = JsonConvert.DeserializeObject(resultString); To receive objects
