How do I enumerate through a JObject?

Question

I\'m trying to determine how to access the data that is in my JObject and I can\'t for the life of me determine how to use it.

JObject Object = (JObject)Resp         


        

Answer 1

The answer did not work for me. I dont know how it got so many votes. Though it helped in pointing me in a direction.

This is the answer that worked for me:

foreach (var x in jobj)
{
    var key = ((JProperty) (x)).Name;
    var jvalue = ((JProperty)(x)).Value ;
}

If you look at the documentation for JObject, you will see that it implements IEnumerable<KeyValuePair<string, JToken>>. So, you can iterate over it simply using a foreach:

foreach (var x in obj)
{
    string name = x.Key;
    JToken value = x.Value;
    …
}

For people like me, linq addicts, and based on svick's answer, here a linq approach:

using System.Linq;
//...
//make it linq iterable. 
var obj_linq = Response.Cast<KeyValuePair<string, JToken>>();

Now you can make linq expressions like:

JToken x = obj_linq
          .Where( d => d.Key == "my_key")
          .Select(v => v)
          .FirstOrDefault()
          .Value;
string y = ((JValue)x).Value;

Or just:

var y = obj_linq
       .Where(d => d.Key == "my_key")
       .Select(v => ((JValue)v.Value).Value)
       .FirstOrDefault();

Or this one to iterate over all data:

obj_linq.ToList().ForEach( x => { do stuff } );

JObjects can be enumerated via JProperty objects by casting it to a JToken:

foreach (JProperty x in (JToken)obj) { // if 'obj' is a JObject
    string name = x.Name;
    JToken value = x.Value;
}

If you have a nested JObject inside of another JObject, you don't need to cast because the accessor will return a JToken:

foreach (JProperty x in obj["otherObject"]) { // Where 'obj' and 'obj["otherObject"]' are both JObjects
    string name = x.Name;
    JToken value = x.Value;
}
