Get item from JSON Odata list for UWP - json

Question

I have been having a hard time trying to figure this out that I've just about torn out all my hair now.
Using this section of code (Added a var result that I looking at with a stoppoint):
public async Task<string> GetHttpSPContentWithToken(string url, string token)
{
var httpClient = new System.Net.Http.HttpClient();
System.Net.Http.HttpResponseMessage response;
try
{
var request = new System.Net.Http.HttpRequestMessage(System.Net.Http.HttpMethod.Get, url);
//Add the token in Authorization header
request.Headers.Authorization = new System.Net.Http.Headers.AuthenticationHeaderValue("Bearer", token);
response = await httpClient.SendAsync(request);
var content = await response.Content.ReadAsStringAsync();
var result = JsonConvert.DeserializeObject<SharePointListItems.Fields>(content);
return content;
}
catch (Exception ex)
{
return ex.ToString();
}
}
The content that I receive is this (updated getting rid of extra information):
{
"#odata.context": "https://graph.microsoft.com/v1.0/$metadata#sites('root')/lists('FBA0AB63-8453-4BB9-AA17-142A5D72A50D')/items/$entity",
"#odata.etag": "\"60d40002-0f08-4f29-afa7-0287137b863b,1\"",
"createdDateTime": "2018-08-07T14:28:47Z",
"eTag": "\"60d40002-0f08-4f29-afa7-0287137b863b,1\"",
"id": "1",
"lastModifiedDateTime": "2018-08-07T14:28:47Z",
"webUrl": "https://XXXX.sharepoint.com/Lists/TestList/1_.000",
"createdBy": {
"user": {
"email": "XXXX#XXXX.onmicrosoft.com",
"id": "b5f81cc6-f8b7-46b7-8e10-6ce1b9689c23",
"displayName": "TK"
}
},
"lastModifiedBy": {
"user": {
"email": "XXXX#XXXX.onmicrosoft.com",
"id": "b5f81cc6-f8b7-46b7-8e10-6ce1b9689c23",
"displayName": "TK"
}
},
"parentReference": {},
"contentType": {
"id": "0x010001403BD420356E4ABE3B63E5AEC0713D"
},
"fields#odata.context": "https://graph.microsoft.com/v1.0/$metadata#sites('root')/lists('FBA0AB63-8453-4BB9-AA17-142A5D72A50D')/items('1')/fields/$entity",
"fields": {
"#odata.etag": "\"60d40002-0f08-4f29-afa7-0287137b863b,1\"",
"Title": "1",
"UserName": "TK",
"UserAge": "47",
"UserTitle": "Developer"
}
}
I just want the values forUserAge, UserName, and UserTitle to put each into a textbox, but not sure how to pull them out.
I am pretty sure that I need to set up a class of some sort, but it is the #odata parts that are breaking my back.
Everything that I have tried just gives me back a null value. I see the value there, just not sure how to parse/pull it out.
I have looked at this (updated):
using Newtonsoft.Json;
using System;
public class SharePointListItems
{
public class UserCreated
{
public string email { get; set; }
public string id { get; set; }
public string displayName { get; set; }
}
public class CreatedBy
{
public UserCreated user { get; set; }
}
public class UserModified
{
public string email { get; set; }
public string id { get; set; }
public string displayName { get; set; }
}
public class LastModifiedBy
{
public UserModified user { get; set; }
}
public class ParentReference
{
}
public class ContentType
{
public string id { get; set; }
}
public class Fields
{
[JsonProperty("#odata.etag")]
public string ODataETag { get; set; }
public string Title { get; set; }
public string UserName { get; set; }
public string UserAge { get; set; }
public string UserTitle { get; set; }
}
public class RootObject
{
[JsonProperty("#odata.context")]
public string ODataContext { get; set; }
[JsonProperty("#odata.etag")]
public string ODataETag { get; set; }
public DateTime createdDateTime { get; set; }
public string eTag { get; set; }
public string id { get; set; }
public DateTime lastModifiedDateTime { get; set; }
public string webUrl { get; set; }
public CreatedBy createdBy { get; set; }
public LastModifiedBy lastModifiedBy { get; set; }
public ParentReference parentReference { get; set; }
public ContentType contentType { get; set; }
[JsonProperty("fields#odata.context")]
public string FieldsODataContext { get; set; }
public Fields fields { get; set; }
}
}
But then I run into the issue that there is two [JsonProperty("#odata.etag")].

Answer 1

The [JsonProperty] custom attribute is added to the C# property that actually holds that value. Instead of putting the attribute on the Title or createDateTime property, you need to put them on their own properties:
public class RootObject
{
[JsonProperty("#odata.context")]
public string ODataContext { get; set; }
[JsonProperty("#odata.etag")]
public string ODataETag { get; set; }
// No attribute needed here
public DateTime createdDateTime { get; set; }
// etc...
Also, you are trying to parse the content as a Fields class, but it is a RootObject; you need to use
JsonConvert.DeserializeObject<SharePointListItems.RootObject>(content)
To get the object.
