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'm trying to parse this array using JSON.NET

I am attempting to parse some json I am getting back from a service.For example it's returning
[Code]...
I'm new at JSON and i am currently struggling with a problem parsing JSON data in a list of objects.The data that i am trying to parse is generated by the facebook graph api, and looks like this :
{
"100001621071794": {
"id": "100001621071794",
"name": "TEST1",[code].....
I know that this is not an array, because it is missing '[' and ']'. But when i replace the '{' and '}' with '[' and ']' i'm getting an error because of an invlaid matrix.
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'm strugling the whole day with the next JSON string
{
"0":{"link":"afbeeldingenplaatje1.jpg"},

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

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.
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 would like to be able to parse vb.net code files, so I can examine the collection of Subs, Functions (and their contents, including comments), private variables, etc. I can be open the actual source code files. So for example, if I have:

I'm creating a vb.net winforms application that will take in user given strings, parse them, and print out labels with variable information. The given string will be used in all the labels, but the variable part of the string will change with each label.
My question is: is it better to parse the strings one time, then store those values in arrays, or to parse the string each time a label is printed? Which will perform better? Which is better practice? What is the proper way to test something like this?
I have been working on a project to read some data of facebook user walls. So I have researched I need to use json and System.Web.Script.Serialization to extract the required data I suppose. Has anyone have a tidy example of how to get something out of json script?
View 2 RepliesI 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 successfully wrote a code to retrieve a version number from a HTML page which is this:
<div class="header">Latest Version: <span class="version">6.59</span></div>
So the following code will return the version number which currently is 6.59 which is what I'm after. [Code] But then i remembered that releases are done as following: 6.59, 6.59b, 6.59c, 6.60, 6.60b etc. So when the b version of 6.59 is released the parser will still return 6.59. So how can i make this code better?
After countless hours of searching I have been unable to get this code to work. If anyone can provide we with an alternative. I know the easiest way is to use the Split() function but im trying to do an alternative method by identifying the spaces within the string and splitting them up.
I tried the search function, but to no avail.
Attached is the code.

I'm trying to find a way to parse a string which looks like this:
1,394,7,0,0,0,0,0,,0,0,63,85,0,,0,0/2,595,59,8,0,0,0,0,0,,,0,0,,0,8,6,0/3,696,0,0,0,0,,,0,0,,84,0,0/#
So that it only reads the first two digits, then delete everything after that till it reads a "/", read the first two digits and delete everything up to the "/" again.This would result in this:
1,394
2,595
3,696
I don't know how to remove every character after the last of the first two digits up to the first / it reads, can anyone help me with that?How can I parse this code easily?
I have a large XML database of song files. I basically want to parse this into a listview with two columns. "Artist" and then a subitem of "Song"
And example of one <song></song> section of the database is:

Then put Author in the Item and Title as a subitem. How would I go about doing this on startup to a database that has thousands of songs?
