View 1 RepliesJavascript - Accessing Elements Of JSON Object Without Knowing The Key Names

Is there any way of accessing the keys and values (in javascript) in this array without knowing what the keys are?

View 1 RepliesTwitter Json - Unable To Convert To Jobject Or Jarray Using Json.net / Javascriptserializer?
May 9, 2012I am been stuck on this for 3 days now...I have been accessing the twitter api to pull a user_timeline for a list of users and the json that comes back is impossible to work with. I tried to deserialize it using javascriptserializer and get an error:invalid object passed in , ':' or '}'
Now this is frustrating since I expect the json being returned to be error free. Then I tried json.net and split the posts using string.split and tried to convert each post to Jobject or jarray. for Jarray I get

Now I have formatted the code here and not pasted the whole file but it does look like valid json to me and I do not alter anything after receiving the stream from the twitter api. Can someone please point me in the right direction? I really need to get this stuff parsed?

Convert JSON To Array OR JSON To XML?
Jul 17, 2011How can I convert a JSON string to an array OR a JSON string to XML in VB.NET? I know how to do this in C#, as I have read dozens of articles on it, however, I am unable to figure out how to achieve the same result in VB.NET.

I'm willing to use an additional DLL file if needed.
Using JSON.NET To Parse JSON Generated Through PHP?
Mar 2, 2010I'm sure this has been asked before but I'm not finding quite the information I'm needing so I thought I'd post this.
I've written a PHP script that returns a simple JSON object that looks like this:
{"status":"success","level":"admin"}
I'm doing a standard web request that submits the required data to the script over the internet and that's working fine.
Now, I want to use JSON.NET to pull out the individual variables so I can know what the values of "status" and "level" are. The problem is, I have no idea where to start.
I'm doing this in VB.NET (on the .NET Compact Framework).
C# - Return Value Of "count" Property In JSON Object
May 24, 2012I 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.
.net - JSON Parsing Using JSON.net?
Feb 15, 2011I am accessing the facebook api and using the json.net library (newtonsoft.json.net)I declare a Jobject to parse the content and look for the specific elements and get their values. Everything works fine for the first few but then I get this unexplained nullexception error " (Object reference not set to an instance of an object)Now I took a look at the declaration but cannot see how to change it. Dim jobj as JObject = JObject.Parse(responseData) message = jobj("message").tostring
The error occurs at the last line above.I check to see if message is null and then look for the next desired field as follows
[Code]...
This is one example where "message" does not appear in the first few lines but appears later. So what I do is look for position of message and description and which ever is first go and get that and if I get an error or the fields do not return anything, I try and parse by regex and even that is not working right.
Send An Object Over A Network Stream
Oct 18, 2010So i'm still goofing around with this chat app thing. Current when a user sends a message it sends to all clients connected. The server stores all clients and their IPs in a hash table, so what i want to do is each time a client joins, the server will broadcast the updated hashtable to each client. I know i can make a mess and get the server to broadcast each row of the hash table as a string but i think this way would be cleaner, either that or send the client object instead of the whole hash table.
