I have a JSON string and I need some help to deserialize it.
Nothing worked for me... This is the JSON:
{
"response": [{
"loopa": "81ED1A646S894309CA1746FD6B57E5BB46EC18D1FAff",
"drupa": "D4492C3CCE7D6F839B2BASD2F08577F89A27B4ff",
"images": [{
"report": {
"nemo": "unknown"
},
"status": "rock",
"id": "7e6ffe36e-8789e-4c235-87044-56378f08m30df",
"market": 1
},
{
"report": {
"nemo": "unknown"
},
"status": "rock",
"id": "e50e99df3-59563-45673-afj79e-e3f47504sb55e2",
"market": 1
}
]
}]
}
I have an example of the classes, but I don't have to use those classes. I don't mind using some other classes.
These are the classes:
public class Report
{
public string nemo { get; set; }
}
public class Image
{
public Report report { get; set; }
public string status { get; set; }
public string id { get; set; }
public int market { get; set; }
}
public class Response
{
public string loopa { get; set; }
public string drupa{ get; set; }
public Image[] images { get; set; }
}
public class RootObject
{
public Response[] response { get; set; }
}
I want to mention that I have Newtonsoft.Json already, so I can use some functions from there.
How can I do this?

You could use the nuget package Newtonsoft.JSON
in order to achieve this:
JsonConvert.DeserializeObject<List<Response>>(yourJsonString)

I also had the issue of parsing and using JSON objects in C#. I checked the dynamic type with some libraries, but the issue was always checking if a property exists.
In the end, I stumbled upon this web page, which saved me a lot of time. It automatically creates a strongly typed class based on your JSON data, that you will use with the Newtonsoft library, and it works perfectly. It also works with languages other than C#.

First install newtonsoft.json
package to Visual Studio
using NuGet Package Manager
then add the following code:
ClassName ObjectName = JsonConvert.DeserializeObject < ClassName > (jsonObject);

You can solve your problem like below bunch of codes
public class Response
{
public string loopa { get; set; }
public string drupa{ get; set; }
public Image[] images { get; set; }
}
public class RootObject<T>
{
public List<T> response{ get; set; }
}
var des = (RootObject<Response>)Newtonsoft.Json.JsonConvert.DeserializeObject(Your JSon String, typeof(RootObject<Response>));

I solved this problem to add a public setter for all properties, which should be deserialized.

public static void Main(string[] args)
{
string json = @" {
""children"": [
{
""url"": ""foo.pdf"",
""expanded"": false,
""label"": ""E14288-Passive-40085-2014_09_26.pdf"",
""last_modified"": ""2014-09-28T11:19:49.000Z"",
""type"": 1,
""size"": 60929

]
}";
var result = JsonConvert.DeserializeObject<ChildrenRootObject>(json);
DataTable tbl = DataTableFromObject(result.children);
}
public static DataTable DataTableFromObject<T>(IList<T> list)
{
DataTable tbl = new DataTable();
tbl.TableName = typeof(T).Name;
var propertyInfos = typeof(T).GetProperties();
List<string> columnNames = new List<string>();
foreach (PropertyInfo propertyInfo in propertyInfos)
{
tbl.Columns.Add(propertyInfo.Name, propertyInfo.PropertyType);
columnNames.Add(propertyInfo.Name);
}
foreach(var item in list)
{
DataRow row = tbl.NewRow();
foreach (var name in columnNames)
{
row[name] = item.GetType().GetProperty(name).GetValue(item, null);
}
tbl.Rows.Add(row);
}
return tbl;
}
public class Child
{
public string url { get; set; }
public bool expanded { get; set; }
public string label { get; set; }
public DateTime last_modified { get; set; }
public int type { get; set; }
public int size { get; set; }
}
public class ChildrenRootObject
{
public List<Child> children { get; set; }
}

shareInfo is Class:
public class ShareInfo
{
[JsonIgnore]
public readonly DateTime Timestamp = DateTime.Now;
[JsonProperty("sharename")]
public string ShareName = null;
[JsonProperty("readystate")]
public string ReadyState = null;
[JsonProperty("created")]
[JsonConverter(typeof(Newtonsoft.Json.Converters.UnixDateTimeConverter))]
public DateTime? CreatedUtc = null;
[JsonProperty("title")]
public string Title = null;
[JsonProperty("getturl")]
public string GettUrl = null;
[JsonProperty("userid")]
public string UserId = null;
[JsonProperty("fullname")]
public string Fullname = null;
[JsonProperty("files")]
public GettFile.FileInfo[] Files = new GettFile.FileInfo[0];
}
// POST request.
var gett = new WebClient { Encoding = Encoding.UTF8 };
gett.Headers.Add("Content-Type", "application/json");
byte[] request = Encoding.UTF8.GetBytes(jsonArgument.ToString());
byte[] response = gett.UploadData(baseUri.Uri, request);
// Response.
var shareInfo = JsonConvert.DeserializeObject<ShareInfo>(Encoding.UTF8.GetString(response));

I had a scenario, and this one helped me
JObject
objParserd = JObject
.Parse(jsonString);
JObject
arrayObject1 = (JObject
)objParserd["d"];
D
myOutput= JsonConvert
.DeserializeObject<D>
(arrayObject1.ToString());

I am using like this in my code and it's working fine
below is a piece of code which you need to write
using System.Web.Script.Serialization;
JavaScriptSerializer oJS = new JavaScriptSerializer();
RootObject oRootObject = new RootObject();
oRootObject = oJS.Deserialize<RootObject>(Your JSon String);

I am using following:
using System.Web.Script.Serialization;
...
public static T ParseResponse<T>(string data)
{
return new JavaScriptSerializer().Deserialize<T>(data);
}

If you use C# 2010 or newer, you can use dynamic type:
dynamic json = Newtonsoft.Json.JsonConvert.DeserializeObject(jsonstring);
Then you can access attributes and arrays in dynamic object using dot notation:
string nemo = json.response[0].images[0].report.nemo;

Should just be this:
var jobject = JsonConvert.DeserializeObject<RootObject>(jsonstring);
You can paste the json string to here: http://json2csharp.com/ to check your classes are correct.
