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.
I am looking for a vb.net library where I can insert data into an object and have it spit out a json formatted string, and also take the string in again to rebuild the object.I am not that concerned with mapping it to preexisting objects.I have searched around and every single library I've found either can't read the strings in again, interprets them as one long string instead of breaking them up into parts, or fails to work entirely (asp.net can't even find any public members).

View 1 RepliesI'm trying to setup a WCF web service to be consumed by JavaScript using JSON and jQuery.I've noticed that you can send JSON without a DataContract if the service method parameters match the naming structure of the JSON object:

<AspNetCompatibilityRequirements(RequirementsMode:=AspNetCompatibilityRequirementsMode.Allowed)>

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)
I have added a DataSet to connect with my SQLDatabase. Test Query displays correct values but when I programmatically try to display the value of a certain field using following code
dim vrName= dsTest.Tables(tblTest).rows(0).items(0)
I get Tables is not a member of dsTest.
how can I use dataset to read, write, edit and delete data as we use in WinForms?
I have a JSON object that looks like this.
{
"Errors":{
"err1":[

Dim jObject As JObject = jObject.Parse(jsonText )
Dim jErrors As JToken = jObject("Errors")
Dim jS = New JsonSerializer()

View 6 RepliesI 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.
