Deserializing Server returned String to JSON

Question

I am using the SharePoint REST API to do a search. I am pulling back the JSON results and reading them as follows:

HttpWebRequest endpointRequest = (HttpWebRequest)HttpWebRequest.Create(querystring);

endpointRequest.Method = "GET";
endpointRequest.Accept = "application/json; odata=verbose";
endpointRequest.UseDefaultCredentials = true;
HttpWebResponse endpointResponse =(HttpWebResponse)endpointRequest.GetResponse();

Stream webStream = endpointResponse.GetResponseStream();
StreamReader responseReader = new StreamReader(webStream);
var results = responseReader.ReadToEnd();

This works fine, I can see the results in JSON format. So I created a class from the JSON in VS 2017 and here is the classes created from the JSON (this was done automatically with File=>Paste Special=>Paste JSON As Classes:

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;

        public class Result

        }

        public class Rows

            public Result1[] results { get; set; }
        }

        public class Result1
        {
            public __Metadata6 __metadata { get; set; }
            public Cells Cells { get; set; }
        }

        public class __Metadata6
        {
            public string type { get; set; }
        }

        public class Cells
        {
            public Result2[] results { get; set; }
        }

        public class Result2
        {
            public __Metadata7 __metadata { get; set; }
            public string Key { get; set; }
            public object Value { get; set; }
            public string ValueType { get; set; }
        }

        public class __Metadata7
        {
            public string type { get; set; }
        }

        public class Properties1
        {
            public Result3[] results { get; set; }
        }

        public class Result3
        {
            public __Metadata8 __metadata { get; set; }
            public string Key { get; set; }
            public string Value { get; set; }
            public string ValueType { get; set; }
        }

        public class __Metadata8
        {
            public string type { get; set; }
        }

        public class Secondaryqueryresults
        {
            public __Metadata9 __metadata { get; set; }
            public object[] results { get; set; }
        }

        public class __Metadata9
        {
            public string type { get; set; }
        }

        public class Triggeredrules
        {
            public __Metadata10 __metadata { get; set; }
            public object[] results { get; set; }
        }

        public class __Metadata10
        {
            public string type { get; set; }
        }

    }
}

So I now am trying to deserialize the results as follows:

 SharePointRESTResults resultX = JsonConvert.DeserializeObject<SharePointRESTResults>(results());

The results I need should be in the Result2 Class. The problem I have is that this line is setting resultX = to "ConsoleApplication1.SharePointRESTResults" and nothing more. I looked in the JSON Serializing and Deserializing here: JSON Documentation but still cannot get the results into the class so I can pull out the data. I appreciate any help.

Answer 1

The main points are -

• The Account Declaration.
• JsonProperty attribute.

NOTE : If you have an object Which keys can change, Then you need to use a

 Dictionary<string, T> 

. A regular class won't work for that; neither will a

 List<T> 

.
