Twitter Json - Unable To Convert To Jobject Or Jarray Using Json.net / Javascriptserializer?
May 9, 2012
I 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
'unexpected end of content while loading jArray
[Code]...
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?

I am trying to deserialize a JSON string that looks like so: {'type':'clientlist','client_list':[]} I am using JavaScriptSerializer() to do it. For some reason the JavaScriptSerializer() is choking on the member 'client_list'. It doesn't give very good info. The error it gives is:

I have a JSON response from a web service that I need to be converted to an object then to an array. My response is similar to the one below:
{"status":{"error":"NO","code":"200","description":"none","message":"Request ok"},"geolocation":{"lat":"38.89515","lng":"-77.0310"},"stations":[{"country":"United States","regPrice":"0.00","midPrice":"0.00","prePrice":"0.00","streetAddress":"1401, I St[code]....
I am doing this is VB.NET within a console for now. Basically I am trying to create a simple way to test my API calls and output the information. What I am trying to accomplish is having to loop through the JSON array and list the stations.

How 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 using the System.Web.Script namespace via System.Web.Extensions.dll (from Microsoft).
I'm willing to use an additional DLL file if needed.

How can i deserialize this? What's wrong with the next code (vb.net)

I'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).

I recently made a transition to VS2010 from vb6, it's quite a change for me and I'm still learning most of the functionality.I have a project that reads a web server for xml files and saves them into a file directory, works great in vb6, but I haven't a slightest idea how to achieve the same thing in visual studio. I've read a whole bunch of threads on the topic and wrote a few lines of code without any success. For example there is an xml file that resides on the web [URL] how can I take it down and most importantly convert it into json? I've read about json.net but I can't find a single example with syntax.

I 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.

I have two experimental web services. One is an asmx contained within a .net web application. The other is a WCF service library being invoked from the web application.The asmx basically does everything I need, but I think WCF would be better, except that it doesn't do anything as I would expect after fiddling with the asmx service.For example, the same method behaves differently in each:
' ASMX
<WebMethod(BufferResponse:=True, EnableSession:=False)>
Function Test(aObject as Object) as Object
' object will have been successfully serializaed into a dictionary

I have to send a request to Webservice and I have a working PHP solution, that I have to translate in VB.net
Here's the code working in PHP
//fill in the details of the contacts.userId is obtained from loginResult.
$contactData = array('lastname'=>'Valiant', 'assigned_user_id'=>$userId);
//encode the object in JSON format to communicate with the server.
[code]....
Naturally I imported a reference to a Json library and Imported (Imports Newtonsoft.Json)?

I'm trying to understand how to actually use, and create JSON data.
StringBuilder sb = new StringBuilder();
StringWriter sw = new StringWriter(sb);
using (JsonWriter jsonWriter = new JsonTextWriter(sw))
[code]....
and I am sure it does... but how do I view it? How do I turn that into an object that the browser can output.It seems to me that the first stage I need to resolve is "how to create" JSON files/strings, next stage will be how to actually use them. If it helps answer the question, what I'm aiming for initially is to be able to use AJAX Autocomplete from a search page generated from my MySQL database, I was hoping I could write a simple SQL query and have that returned using something similar to the above?

Alright I have been trying to figure this out and I read the MSDN page on the JavaScriptSerializer. However, I still can't figure out how to get this to work on an asp.net page. I want to convert my dataset into a json string so I can graph it using FLOT(graphing tool) imports System.Web.Script.Serialization
dim myObject = dataset.getxml()dim jsonString = new JavaScriptSerializer().Serialize(myObject)
