C# - Return Value Of "count" Property In JSON Object

I have a json object from the facebook api

"comments": {
"count": 2
},
"updated_time": "2012-05-24T02:46:36+0000"

The entire json object is a dynamic object.

I can easily read the value of the updated_time with:

post.updated_time

However this returns the count of items in the collection, not the value of the "count" property in the json object.

post.comments.count

Is it possible to get the value of post.comments.count without it using the "count" keyword?

I should note that the JSON is much larger than this. If there are actually comments there is another collection of the actual comments so something like post.count(0) would not work in that case.
