How determinate if Json that I receive is blank

Question

I have a function that receive a JObject, and in one case the Json that I receive are this:

{}

and I was trying to manage with this:

 public void GetSomeJson(JObject request)
    {
          if (request==JObject.Parse("{}"))
              throw new ArgumentNullException("The request are null");
          //more stuff
    }

In this way doesn't work, and jump the condition, any idea to recognize the Json received is null or blank?

This is not a duplicate (of that particular question, anyway). The answers to that question will not help OP with this question. — cdhowie, Sep 09 '14 at 22:06

JObject is a container for properties and implements IDictionary<string, JToken> to access them, so this would test if an object has zero properties:

if (request.Count == 0) { /* The object is empty */ }

public void GetSomeJson(JObject request)
    {
            if ( request != null && request.Count == 0 ) 
              throw new ArgumentNullException("The request are null");

    }

`ArgumentNullException` doesn't make sense when the object is empty but not null. Maybe `ArgumentException`, but if the object isn't null then ANE is not appropriate. – cdhowie Sep 10 '14 at 05:43
sure you can add couple of more lines :) – codebased Sep 10 '14 at 05:49
