JObject Error parsing comment

Question

Trying to get some information about a youtube video:

http://gdata.youtube.com/feeds/api/videos/BDQqSnSEuyk?v=2&alt=jsonc&callback=storeInfo

The result is JSON.

I try using deserialize it with JSON.net:

JObject JObj = (JObject)JsonConvert.DeserializeObject(gDataResult);

I get this error:

Error parsing comment. Expected: *, got /. Path '', line 1, position 1.

It is because of the single // comment.

Regex.Replace(subjectString, ".*//.*$", "$1/*$2*/"); not working, has tried it. — Alvin, Nov 28 '13 at 13:22
@EvanTrimboli: this is not duplicate, the target thread has nothing to do with JSON-P which the URL points at. — quetzalcoatl, Nov 28 '13 at 13:29

You have to be more careful when reading the data file. This is not JSON. This is JSON-P. Even the URL you provided suggests that: note the callback=storeInfo at the end.

The JSON-P differs from JSON in that the object is wrapped in a function call:

// API callback
storeInfo({"apiVersion":"2.1","..... }}});

To be a plain JSON, it needs to be just

// API callback
 {"apiVersion":"2.1","..... }}};

With this serivce, just use an url of http://gdata.youtube.com/feeds/api/videos/BDQqSnSEuyk?v=2&alt=jsonc without the 'callback' section and you'll get a normal JSON response.
