I am trying to read JSON data from a server to a dataset object, any idea on how this can be done. I have tried using the DataContractJsonSerializer class but it only seems to work for objects.
JSON Data
{
"firstName": "John",
"lastName": "Smith",
[code]....
The code above works to an object, but I want to parse the JSON data to a dataset object.
{"AliasName": "ysiCountryInfo", "DataClass": {"Description":"United States 111","Code":"usa","WriteOffTaxPointAdjustment":0,"IndexationRounding":6}} I would like to deserialize object into below class
how to receive and send back json. Hope someone can help me on this. I understand by examples.
On my clientside, I am sending a ajax json string "name":"theName" to the server side and would like the server side to return a string saying "welcome &name ".
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).
I have a task to create a web service to receive client-side app's http request(with rpc={json data} in the end), deserilize it and put he parameter in stored Procedure in order to retrive data from sql server. the procedure query and client-side's app are already there and the return data to client-side app is JSON too
I'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:
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?
PD: I'm currently using Newtonsoft's JSON.Net library.
Public Sub New(ByVal jsonText As String) Dim jObject As JObject = jObject.Parse(jsonText ) Dim jErrors As JToken = jObject("Errors") Dim jS = New JsonSerializer()
I am writing a program with VB.NET, there I have to select data from one table. Then I have to update about 4 tables and insert to 2 Tables. Which approach will be ok for me? I'm thinking to use DataSet.
I have a problem in returning a value in JSON in vb .net.[code]My scenario is that, when i pressed the button then it should alert the value returned by the getValue function but in my case it always alert an error of [Object Object].
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.
From VB.net code behind when I am trying to deserialize it it's stating that "Expecting state 'Element'.. Encountered 'Text' with name '', namespace ''."
I want to read data from xml into memory. My code works fine providing I only have one record in XMl file. If I have more than 1 record the program fails.[code]...
When a json result is returned by the controller the object name seems to be missing, I normally wouldn't mind but the flexbox jquery plugin requires the json result in a particular format.
